　　The Best GPS Trackers of 2024 Best Overall GPS Tracker: Bouncie Best Budget GPS Tracker: Tracki Best GPS Tracker With Waterproof Box: Spytec GL300 Mini Best GPS Tracker for No Subscription: Apple AirTag Best GPS Tracker for Zero Cell Service: LandAirSea 54 Best Overall GPS Tracker Bouncie Specs Base monthly subscription $10 Battery life Vehicle-powered GPS network 4G LTE Weight 1.13 oz. Size ‎1.87” x 1.75” x 1”

　　Pros Real-time updates of vehicle movements and speed Vehicle health and maintenance monitoring Expansive app for monitoring and recording data Cheap monthly subscription Cons Easy to find and remove if a vehicle is stolen Only works when the vehicle is turned on Only works on 1996 and newer vehicles Eric Phillips By far, our favorite GPS tracker for tracking a car goes to the Bouncie ($90). The tracker works by plugging into your vehicle’s OBD II port. From there, it not only gets power, so you don’t have to worry about charging or replacing batteries, but it also connects to your vehicle’s computer and can start tracking a plethora of your vehicles data. This data includes the health of the vehicles engine and battery, fuel levels, hard acceleration/braking, speeding, idle time, trip fuel economy, distance driven, impact detection, and curfews.

　　Not only did the tracker monitor and alert us via email and SMS, but it also did so on a very easy-to-use app. The app shows your vehicle’s location in real-time and logs every data point above. You can easily see where your vehicle is headed and how fast it’s going at any point while the vehicle is powered on and in cell range.

　　While the price of the tracker is considerably higher than the other trackers at $90, the monthly subscription at $10 is the lowest available, and there are no monitoring levels, meaning it shows real-time updates all the time. 

　　While we loved the data provided, the app user interface, and the alerts available, there are a few downsides to the Bouncie. First and foremost, you can’t hide the tracker at all. It’s very easy to find and remove from the OBD II port, and any educated vehicle thief or high schooler can easily remove it.

　　Second, the tracker only works when the vehicle is powered on, so if your vehicle gets towed or the battery is dead, there is no tracking. Lastly, this is only compatible with vehicles made in 1996 or newer, as OBD II ports were not required in vehicles made prior to that date. Overall, if you are looking for a vehicle tracker and your vehicle has an OBD II port, we would choose the Bouncie, time and time again 

　　$90 at Amazon Best Budget GPS Tracker Tracki GPS Specs Base monthly subscription $20 Battery life 5-60 days GPS network 4G LTE / 3G / 2G Weight 1.26 oz. Size 1.75”×1.6”×0.6”

　　Pros Cheapest priced unit SOS and pre-chosen text buttons Consistent and reliable email and SMS alerts Wide range of accessories for variety of use cases Cons Short battery life Tiered subscriptions can limit functions Eric Phillips For being small and lightweight, the Tracki ($13) is loaded with features and is 4G LTE connected. While this was the cheapest option we tested, it also came with the most accessories and had a low monthly subscription of $20 or as low as $10 for an annual subscription. 

　　One thing the Tracki has down is notifications: It has the ability to send push notifications, email, and SMS updates, including movement, speed, geofence, low battery, two preset messages, and an SOS alert.

　　From our testing, we found the device to be very sensitive to movement; the simple act of getting into our truck would trigger the alert compared to the others, which needed the truck to be driven before their movement alerts were triggered physically. The preset messages and SOS alerts were limited to 30 per month combined before incurring additional charges. 

　　The app took a bit of time to figure out, but once we were familiar, we were able to quickly and easily view the map in real-time, check alerts, set notifications, and more. The Tracki comes out of the box with a handful of handy accessories, including a water-resistant case, belt clip, magnetic cover, lanyard, and Velcro stickers. Additionally, online, you can purchase larger batteries, a hardwire kit for a car battery, and an OBD II port to power cable, making the Tracki very versatile for different uses. 

　　Also, the monthly subscriptions do come in multiple tiers and price structures depending on how many devices you have and how many seconds between updates from 60 seconds down to 15 seconds. The battery life was the shortest of the ones we tested in full tracking mode, but it does have a battery saver mode where it will only turn on to track at specific intervals that can help improve battery life.

　　Overall, the low price of the GPS itself and the monthly subscription without a lack of features or accessories rocketed the Tracki into our best budget choice. 

　　$10 at Amazon Best GPS Tracker With Waterproof Box Spytec GL300 Mini Specs Base monthly subscription $23 Battery life 9-14 days GPS network 4G LTE Weight 3.2 oz. Size 3.15″ x 1.15″ x 1.64″

　　Pros Comes with waterproof, magnetic box Easy-to-use phone app Reliable notifications SOS button Cons Alerts managed in web app only Bulky when using waterproof, magnetic box Eric Phillips The Spytec GL300 Mini ($18) is another great vehicle tracker. Its rugged, durable, waterproof magnetic box makes it a perfect option for tossing underneath or outside a trailer, truck, car, or camper. The app is easy to use for real-time monitoring and provides a great set of alerts and notifications delivered via mobile, web, email, and SMS. 

　　This tracker has the ability to record and send notifications about trips taken, speeding, geofence entry/exit, movement, distance traveled, and trip duration, as well as a low battery and charging status. A notification can also be signaled if the SOS button is pressed.

　　While this is an extensive list of alerts, they are only configurable on the desktop app, which, when traveling away from home, can be frustrating. Though the mobile app doesnt allow alert configurations, it does have a wide range of information about the tracker including real-time map updates, how to use it, live support, and more.

　　Although we did like the tracker a lot, it was the largest, heaviest, and bulkiest of the trackers we tested. Though rugged and durable, the weatherproof case was even bulkier, making it hard to conceal on any vehicle. Extra accessories include extended battery cases and hardwire kits.

　　The monthly cost of $23 was on the higher end for subscription tiers as well. Overall, the Spytec was an extremely reliable, accurate, feature-laden tracker. When matched with its weatherproof case, it was the most durable and rugged tracker for mounting on the outside of any vehicle. 

　　$18 at Amazon Best GPS Tracker for No Subscription Apple AirTag Specs Base monthly subscription None Battery life 365+ days  GPS network Bluetooth range of Apple device Weight 0.39 oz. Size ‎0.47” x 4.09” x 3.27”

　　Pros No monthly subscription Easy to hide Long battery life Cons Only works if near other Bluetooth Apple products Alerts others in your vehicle there is an AirTag nearby, which won’t help in cases of theft. Limited features Eric Phillips Youre correct: The Apple AirTag ($25) isnt known as an automotive tracker and it technically doesnt use GPS. But its affordable price tag with no monthly subscription cost, the fact that it functions as a tracker, and its small size and long battery life make it easy to hide in a vehicle. So we wanted to test and include this option in our guide. 

　　The AirTag does not use cell towers or satellites but instead uses Bluetooth to track its devices. Each time the AirTag comes in proximity with another Apple device running iOS 14 or above, it uses that device to ping out and back to your Apple device. The FindMy app shows users the last pinged location on a map and includes lost and find modes. 

　　Thanks to a replaceable CR2032 battery, the AirTags have a claimed 1-year-plus battery life, and our testers four-pack are all on 1 year and 3 months of battery life. Their compact size makes them very easy to stash in a vehicle, backpack, or, really, anything you want to track. 

　　The downside of the AirTags really shows in a few ways. First, there are no alerts like movement, trip start/stop, geofence, and more that we see in all the other trackers. Second, they only work with Bluetooth proximity and wont track without cell coverage or if there are no iOS 14 devices around.

　　Lastly, if someone who isnt the owner starts moving with the AirTag, it will send an alert to their Apple device, letting them know they are being tracked and how to locate the device. Overall, the impressive battery life and $0 monthly fee make the AirTag a great contender for Apple users. 

　　$34 at AmazonCheck price at Apple Best for Zero Cell Service LandAirSea 54 Specs Base monthly subscription $20 Battery life 10-180 days GPS network Global GNSS Satellite Weight 4.8 oz. Size 2.25” x 2.25″ x 0.8″

　　Pros Satellite network works without cell service Energy-saver mode offers extended battery life Real-time tracking Waterproof construction and built-in magnet Cons Phone app can be confusing Limited alerts available Eric Phillips The LandAirSea 54 ($30) was the only tracker that came fully waterproof without an additional case and that used a satellite network instead of cell towers. These two factors alone make it a powerful tool for discreetly and accurately tracking your vehicle or any precious item. 

　　What stands out about this tracker is its enclosure, a small, black circular design not only boasts full waterproof casing, but also has a pinpoint on/off switch and a built-in magnet so you can hide this tracker just about anywhere.

　　Unfortunately, the waterproof charging cover isnt attached and is easy to lose when charging; luckily, they provide a second cover with the box. Additionally, the satellite network can track down to inches, anywhere in the world, compared to cell towers or Bluetooth network trackers. 

　　While the Silver Cloud app isnt the most user-friendly, it does show real-time tracking of your device, satellite connection, and battery life. However, the notifications are limited to geofencing, speed, and battery life.

　　The app is also limited in terms of what you can do, as there is only a history of the movements and not a history of the alerts triggered. On the phone app, you can also manage the energy-saver battery mode, where you can set the tracker to only update every 24 hours, giving upward of 6 months of battery life. 

　　Overall, this is a great stealth tracker for protecting any valuable asset. As long as you dont mind the limited alerts and confusing app, the incredibly accurate satellite network that works anywhere in the world is a good enough reason to choose the LandAirSea. 

　　$40 at Amazon Best of the Rest Brickhouse Security Spark Nano 7 GPS Car Tracker Specs Base monthly subscription $29.99 Battery life 140 days GPS network 4G LTE Worldwide Weight 32.8 oz. Size 6.37 x 4.75 x 2.12

　　Pros Can be used as a smaller stand alone unit or with external battery backup Reasonably priced Strong magnets Cons Very heavy when used with external battery App is mediocre Access to subscription modification/cancellation is restricted to an 800 number Eric Phillips The Brickhouse Security Spark Nano 7 GPS Car Tracker ($130) we used for this test came with an external rechargeable battery for an additional 140 days of use. It also came with a waterproof pelican-style case. The case had a series of strong magnets affixed to the bottom for attaching to your vehicle.

　　We tested this unit with the basic subscription, but there are two other levels of service depending on how intricate you would like to get with your monitoring. A word of caution regarding billing: Brickhouse does not make it easy to change or cancel your plan via the app or the website. You have to call the companys 800 number. 

　　Alongside the tracker, the compatible app does its job for the most part. It could stand to be more aesthetically pleasing considering the type of graphics you can get from an app such as Google Maps. It has a bland, monotone, institutionalized feel. But nevertheless, it delivers.

　　This tracker can be used as a standalone unit without the use of the additional battery. There are 15 days of battery life with just the GPS by itself while on standby and 140 days of use with the aforementioned external battery pack, both of which are rechargeable with the included cords.

　　This GPS tracker, as well as the external battery pack, are designed to fit inside the included waterproof, dust-proof protective case. While it is a snug fit, both pieces can be set inside the padded case. Screwed onto the case are eight impressively powerful magnets for vehicle mounting.

　　Despite the rather heavy 2-pound bundle, it would take quite a jolt on a bumpy road to dislodge it from a vehicle. We were never able to get it to fall off while navigating off-road through the New Mexico desert in a rather seasoned heavy-duty truck with a very stiff suspension. 

　　With an included SIM, this tracker can be used internationally via 4G LTE. This Brickhouse is reasonably priced and would suit fleet vehicles well.

　　A variety of GPS trackers exist with different price points, durability, and functions; (photo/Eric Phillips) How We Tested GPS Trackers Our Expert Testers Lead tester Eric Phillips has been an outdoor professional for the last 10 years along with being an extreme automotive enthusiast. At age 18, he built a truck from the ground up alongside his dad and, while living in Chicago, raced cars. Not one to take a vehicle to a mechanic, Phillips picks up a wrench to complete the maintenance and upgrades his own rigs.

　　Phillips has spent a lot of time using GPS to track himself and his belongings, from working search and rescue, split-boarding from huts, and hunting in the remote high alpine to living full-time at 9,000 feet in Colorado. He loves playing with apps and tracking data across phones, tablets, laptops, and desktops.

　　Tester and photographer Chip Jordan is an all-around outdoorsman and gearhead. He has spent the vast majority of his life wrenching on most anything with an engine and wheels. From a complete frame-off rebuild of a 1973 Jeep CJ5 with his sons to working as a fabricator and mechanic at a motorcycle and hot rod shop, it’s safe to say that Chip has an unquenchable thirst for all things automotive.

　　While nomadically meandering around New Mexico and Colorado, Jordan has used a wide variety of GPS devices and apps to aid him in navigating through his travels, as well as marking those hidden gem campsites and epic fly fishing spots.

　　The Brickhouse Securityis costlier but super durable and magnetized; (photo/Chip Jordan) Our Testing Grounds Our team tested a pool of GPS trackers head-to-head across multiple vehicles and a range of cell service in the Rocky Mountains of Colorado to the remote high deserts of southern New Mexico. Our primary test vehicles included a 2017 Toyota Tacoma, a 2014 Ford F-150, a 2008 Ford F-250, and a Triton Snowmobile Trailer, plus more than a few drivers.

　　Our Testing Process We tested these units side-by-side by placing them all in the same vehicle and setting the same set of alerts, including the trip start/stop, speed, geofencing, and more. Then, we sent off a driver to trigger as many alerts as possible while frantically monitoring each app for notifications, alerts, and data points.

　　Throughout our field tests and personal experience, we determined the best GPS trackers based on various metrics, including subscription costs, GPS coverage, battery life, ease of use, alerts, tracking data, features, reliability of information, warranty, and tracking intervals.

　　Bouncie offered the most frequent and information-loaded live tracking updates; (photo/Eric Phillips) Buyer’s Guide: How to Choose a GPS Tracker Plenty of applications of GPS trackers come to mind, including monitoring an everyday vehicle, trailer, motorcycle, or bike for wear and tear, tax or workplace purposes, or security.

　　GPS trackers are also helpful for safety, as they ensure that you know where loved ones are located in case of an emergency.

　　The Brickhouse Security tracker has extremely strong off-road compatible magnets on the backside; (photo/Chip Jordan) Battery Life Battery life is a super important factor when choosing a GPS tracker. A dead battery wont help if your vehicle gets stolen. If you park your camper in storage all winter and want it tracked, using a tracker that requires charging every 10 days wont make sense. Thatss why considering the battery life is important when picking out your GPS tracker.

　　All of our trackers except the Bouncie run off battery power. The Bouncie uses the vehicle to power the tracker, but that only works if the vehicle is turned on or the car battery is charged. Some tracker models include power or energy-saving modes that preserve battery life by only tracking at certain intervals. Of these, the LandAirSea 54 stands out with its 4- to 6-month battery life in power-saving mode.

　　The Apple AirTag is unique in that it uses a nonrechargeable battery that offers 1 year of battery life, which is great for hiding in places you dont need frequent access.

　　For the LandAirSea 54, Spytec GL300 Mini, Brickhouse Security Spark Nano 7, and Tracki, options are available for extending the battery life. That menu includes extended batteries, which are a great alternative when the vehicle or item you want to track does not provide its own power.

　　If the item you want to track does have its own battery, like a car or truck, hardware kits are available, which let you wire the tracker to the vehicle battery so its always powered. The downside is that wires coming off the battery are easy to find and disconnect in the case of theft.

　　Some GPS trackers include a magnetic cover or box; (photo/Eric Phillips) Monthly Subscription While you might think that GPS trackers are cheap, the real cost of using a tracker comes in the form of a monthly subscription needed to use the product. These monthly subscriptions are why these physical trackers are priced so low. The subscriptions cover connecting the trackers to satellites and cell towers and unlocking functions within the paired apps.

　　The standout product in this category is the Apple AirTag, which doesnt require a monthly subscription to track — just an Apple account. Though its tracking is limited to Bluetooth, and there is no ability to set alerts, the one-time price of the AirTag is very enticing.

　　Second, in the standout aisle is the Bouncie, as its monthly subscription is the cheapest available at only $10 a month. Also, there is no tiered price structure where you pay more per month to track the device in faster intervals.

　　On the opposite end of that is the most expensive subscription-based unit, the Brickhouse Security Spark Nano 7, with a base subscription price of $29. This GPS unit does have a tier-based pricing structure, with additional features becoming available as the monthly price increases.

　　As you compare the prices of each tracker, be sure to note the monthly subscription prices to get a realistic idea of how much each tracker will cost to operate yearly.

　　Side by side, our favorite GPS trackers are similar in size and weight; (photo/Eric Phillips) Specific Design Components While the main feature of a GPS tracker is in its name — being able to keep track of the item — there are a lot of details available that make using certain trackers easier and more enjoyable.

　　One primary aspect is waterproofing. Storing a tracking device outside means its going to get wet eventually. The LandAirSea 54 is the only tracker that comes fully waterproof while the other trackers offer some form of waterproof case.

　　Additional factors that help with outdoor mounting are magnets: The LandAirSea 54 and the Trackiboth come with integrated magnets for mounting while the Spytec GL300 Mini as well as the Brickhouse Security Spark Nano 7 include a magnetized and waterproof case.

　　Some other manufacturing specs we like include battery-saver modes, which prolong the life of the battery, and SOS buttons, which let you send custom messages or an SOS alert. Another design detail is vehicle health monitoring, which lets you monitor a vehicles engine health, battery health, and fuel levels.

　　A range of components exist across our tested GPS trackers from the nearly featureless Apple AirTag to the jam-packed Bouncie.

　　GPS trackers with magnetic capabilities are also water-resistant or waterproof or have a case that offers protection; (photo/Eric Phillips) Real-Time Tracking Real-time tracking refers to tracking an item or seeing where your tracker is in real time as its moving. This is extremely helpful if youre looking for a stolen vehicle thats on the move, or monitoring a family member while they drive.

　　Being able to see in real-time where the tracker is, what speed its going, and where its headed are huge pluses. Our testers were most impressed with the Bouncie when comparing real-time tracking, as it gave the most frequent and also information-heavy updates.

　　While some trackers work in real-time, other trackers only update once every 1 to 3 minutes or in battery-saver modes as spaced out as once every 24 hours. This type of tracking uses less battery and resources but isnt as helpful if youre looking for real-time updates.

　　If youre tracking a family member on a road trip and want to see their progress, a 24-hour update might not be quick enough compared to real-time updates. Most trackers can be switched from real-time tracking into a battery-saver interval tracking mode.

　　Many GPS trackers are so small that they easily fit in the palm of a hand; (photo/Eric Phillips) Alerts Alerts come in various forms. They can be notifications from a web or phone app, an email message, or an SMS text message. Alerts can be set to one, or multiple people or formats for each alert.

　　GPS trackers can send alerts when certain parameters are triggered. These can include movement, trip start/stop, fuel levels, hard acceleration/braking, speeding, idle time, geofencing, trip fuel economy, distance driven, impact detection, curfews, SOS, and more. Weve analyzed the three most important ones below.

　　Geofencing Geofencing refers to creating an area on a map in the shape of a square or a circle. The tracker will monitor this area and send alerts whenever the tracker leaves the set boundary or geofence, and again when it enters a geofence.

　　These can be very helpful when tracking a family member or young driver to ensure they dont leave the local neighborhood, county, or even state. A good tracker should be able to easily set and create alerts for geofences and then receive the alerts immediately when they are triggered.

　　Some GPS trackers are more easily hidden and integrated than others; (photo/Eric Phillips) Speed Speed refers to setting a max speed, like a speed limit on the tracker. Whenever the tracker moves faster than the set limit, an alert will be sent. So whenever you toss the keys to your ride over to a friend or family member, you can say keep it below X miles an hour and get a real-time alert if its broken.

　　Trip Start Stop Probably the most important feature you would want to know from a tracked vehicle is if it starts or stops moving. If your car starts moving without your permission, an alert from a tracker can quickly alert the owner that a theft may be happening and to call the authorities. An alert like this can really help in cases of theft.

　　Trip alerts can also be helpful when tracking family members so you know when they have started, and ended vehicle trips. The Trackihas the most sensitive trip start sensor, as climbing into a vehicle where the tracker was in the center console was enough to trigger a trip start alert.

　　Testing the Brickhouse Security unit; (photo/Chip Jordan) Price Value While all of these price tiers are outlined based on unit price, each tracker has its own monthly subscription costs (with the exception of the Apple Air Tag, which has no monthly fee).

　　Budget Our most wallet-friendly trackers in this guide are the Tracki GPS ($13) and the Spytec GL300 Mini ($18). One of the things to take into consideration with the budget-priced trackers is the tiered subscription pricing. Feature availability is limited if lower-priced subscriptions are selected.

　　It’s also worth noting that certain conveniences that may be easily accessible on higher-priced units, can be a bit more laborious to access with the lower-priced devices. For example, on the Spytec GL300 Mini, the list of features is extensive. But configuring these features to your particular needs must be done via a desktop computer as opposed to being able to configure a device via a cellphone app.

　　The Brickhouse Security Spark Nano 7 is on the larger, heavier side of units; (photo/Chip Jordan) Mid-Tier Sitting in the mid-tier price range are the Apple AirTag ($25) and the LandAirSea 54 ($30).

　　The Air Tag is a great tool, but it does have its drawbacks from the standpoint of vehicle GPS tracking. Our top pick in the midrange is the LandAirSea 54. You get a lot of bang for the buck with this tracker, such as tracking that is accomplished using satellites. This means seamless connectivity and tracking anywhere in the world. You also get a long battery life and a waterproof magnetic case.

　　Premium Finishing out the list in the premium category is theBouncie ($90) and the Brickhouse Security Spark Nano 7 ($130). We highly recommend the Bouncie tracker in this price sector. Premium features like real-time monitoring as well as vehicle health and maintenance, the cheapest monthly subscription, and an extensive app. It is OBDII-specific, so keep that in mind.

　　The Brickhouse tracker is just that: a brick. It’s big and it’s heavy, but it does do its job. This unit is better suited for fleet vehicles.

　　Apple AirTag is sleek, small, and easily fits in an owners manual; (photo/Eric Phillips) Frequently Asked Questions Do all GPS trackers require a monthly fee?  Not exactly. TheApple AirTag, while not technically a GPS tracker, does not require a monthly fee. Every other tracker, though, does require some level of a monthly subscription in order for the tracker to work.

　　Can you tell if someone put a GPS tracker on your car? There are a few ways you can tell if someone has put a GPS tracker on your car. First, check the OBD II port for wires or objects plugged in. Next, check the battery for any additional wires like a hardwired tracker. Lastly, you can do a visual sweep of the vehicle, especially underneath for any small boxes that look suspicious.

　　If there is anApple AirTagon your car, Apple will send a notification that an AirTag is following you around and also instructions on how to find and stop it from transmitting. There is no guaranteed way to know if someone has put a GPS tracker on your car, but if you do suspect someone has, contact the authorities immediately.

　　Certain GPS trackers include an exterior case; (photo/Eric Phillips) Where do you put a GPS tracker on a car? It is recommended when possible to hide a GPS tracker inside or underneath your vehicle. For non-waterproof trackers, the best spots are in the glove box, center console, or underneath the seats.

　　For waterproof trackers with magnets — whether that’s the tracker itself or a waterproof case that you place the tracker inside — you can hide them underneath the vehicle’s car, on a flat metal surface, ideally on the inside or underneath the vehicle’s frame rail.

　　Each tracker comes with instructions on best places to mount. But don’t put trackers close to the engine or exhaust of the vehicle where they can become too hot and stop working.

　　What’s the legality of tracking someone else’s vehicle? In most states, it’s illegal to install a tracker on someone else’s vehicle without their permission. However, that is not the case when it comes to children and parents. But we don’t recommend trying to track someone else’s vehicle or person without their knowledge and permission.

　　The crush-resistant and water-resistant case for the Spytec GPS GL300 Mini GPS Tracker has a magnetic mount with a pull force of nearly 60 pounds; (photo/Eric Phillips) How long will a GPS tracker last on a vehicle? If a GPS tracker is powered by the vehicle and not by a battery and is securely mounted, it can last indefinitely on a vehicle. Battery-powered trackers will only last if their battery remains charged. This can be as short as a week to as long as a year. It’s important to carefully monitor the battery life of any battery-powered tracker.

　　The other factor is mounting the tracker. Trackers mounted inside the vehicle likely won’t fall off, while magnet-mounted trackers underneath a vehicle could get knocked off from impact or rough roads. Luckily, you’ll be able to track and find any GPS tracker you lose from a vehicle.

　　Tracki includes an SOS button; (photo/Eric Phillips) Will any GPS tracker work on any vehicle? Generally, yes. But if you spend a lot of time traveling on rough terrain, you may want to look at a unit that has a very secure mounting system or extremely strong magnets. If you want to track a motorcycle, you need to consider the overall size and weight of the tracker since the available space to mount a GPS unit on a motorcycle can be very limited, as well as the availability of a magnetized surface.
