Looking for a GPS tracker with a magnet? Good idea — magnetic trackers are far easier to install than hardwired ones. Setup and syncing to the app usually takes just a few minutes.

Find a hidden spot under the car, van, or truck, and attach it. That's it.

We put the top 8 magnetic GPS trackers to the test and ranked them on usability, affordability, and accuracy. Here's how each one performed.

Here's how all eight compare at a glance — including which ones actually ship with the magnet, since most of them don't.

One thing before the list: every tracker here is legal to buy and legal to use on a vehicle you own. Putting one on a vehicle you don't own, or using one to follow a person who hasn't agreed to it, is a different question with real legal consequences. There's a fuller note near the bottom of this guide.

1. SpaceHawk Vehicle Tracker — Best Built-In Surface Magnet

SpaceHawk magnetic GPS vehicle tracker

The SpaceHawk was the best magnetic GPS tracker in our testing. We attached it and connected to the app in under 3 minutes, and once we did, it outperformed every other magnetic tracker we tried.

Location accuracy landed at roughly 6 feet, updates arrived as fast as every 3 seconds, and we could share a live link with emergency personnel (thankfully, it was just a test).

Standout features include geo-fencing, multiple alert types, a compact and discreet body, and a waterproof casing.

One thing matters more than anything else with a device like this: does it actually work when you need it to?

If you're tracking a work truck, a trailer, a teen driver in a car you own, or an asset you can't afford to lose, accuracy isn't optional. Quick and cheap sounds tempting until the tracker reports a location 500 feet off, or your vehicle gets taken and the map doesn't update for five minutes. A lot can happen in five minutes.

The SpaceHawk isn't the cheapest model on this list. It is the one that reported fastest and closest in our testing, and on a device whose whole job is telling you where something is right now, that's the spec that counts.

Spec SpaceHawk
Update speed As fast as every 3 seconds
Accuracy Approximately 6 feet
Battery 1500mAh; 2–3 weeks active, several months in power-save
Magnet Built into the case, no separate purchase
Weatherproofing Waterproof housing
Network 4G LTE, SIM included
Warranty Lifetime, with free US-based tech support

Pros

  • Fastest update interval on this list at 3 seconds
  • Tightest accuracy we measured, around 6 feet
  • Magnet built in, so there's no case to buy
  • Waterproof case for all-weather placement
  • Live location link you can hand to a dispatcher
  • Lifetime warranty and US-based support

Cons

  • Not the cheapest hardware here
  • 1500mAh battery is small next to long-standby rivals
  • Frequent updates drain the battery faster
  • Subscription required, like every tracker on this list
  • Magnet strength varies with the surface it's on

2. SpyTec GL300 — Best-Selling Magnetic Mount Tracker on Amazon

SpyTec GL300 GPS tracker

SpyTec GL300 GPS Tracker

  • Compact and portable — fits cars, trucks, boats, and equipment
  • Global 4G coverage across North America and beyond
  • Weatherproof magnetic case available as an add-on

4.1 stars from 7,075 Amazon ratings

Buy on Amazon Watch a video review

The SpyTec GL300 is one of the top-selling magnetic mount GPS trackers on Amazon and our runner-up here. It's close to the SpaceHawk on accuracy, with updates arriving every 5 seconds during testing (on the more expensive plan tier), and the hardware costs roughly $10 less.

The GL300 covers the essentials well — accurate, quick, and simple to set up. The coverage area isn't as broad as the SpaceHawk's (we dropped connection a fair amount) and accuracy trails it slightly, but it's solid for the money.

Worth knowing before you buy: the waterproof magnetic case is a separate purchase, so the sticker price isn't the whole cost.

Spec SpyTec GL300
Update speed As fast as every 5 seconds, adjustable
Battery Up to 13 days depending on update frequency
Magnet Waterproof magnetic case sold separately
Coverage 4G, North America and worldwide
Subscription Plans start around $14.95/month and rise with update speed
Compatibility iOS and Android
Warranty Lifetime while subscribed

Pros

  • 5-second updates on the faster plan tiers
  • Compact enough for vehicles, boats, and equipment
  • Global 4G coverage
  • Historical route review through the Time Machine feature
  • Adjustable update frequency to manage battery

Cons

  • Magnetic waterproof case costs extra
  • Subscription required, and faster updates cost more
  • We dropped connection more often than with the SpaceHawk
  • Only works where there's 4G coverage

★★★★★

Amazon customer, March 2024

One buyer's main complaint is that the monthly plan cost wasn't made clear before purchase, and says they now only switch the device on for trips and when family are travelling.

3. Optimus 3.0 Mini — Best for Fleets and Rough Conditions

Optimus 3.0 GPS tracker

Optimus 3.0 GPS Tracker

  • Live tracking 24/7 through a straightforward app
  • Weeks of battery on a single charge at 1-minute updates
  • Text and email alerts for geofence exits and speed thresholds

4.3 stars from 1,353 Amazon ratings

Buy on Amazon Watch a video review

The Optimus 3.0 Mini is small enough to tuck into a wheel well or behind a bumper without being obvious, which is the main reason it works well on fleet vehicles.

We'd recommend it mainly for fleets, since the subscription tiers bundle features a single-vehicle owner is unlikely to use.

The waterproof case is tough enough to survive a car wash, which matters if your trucks get cleaned regularly.

Overall it's accurate and reasonably priced, running up to two weeks on a charge at 1-minute updates. The two downsides: you need to buy the magnetic case separately, and the subscription starts at $19.95/month and climbs with update speed.

Spec Optimus 3.0
Update speed As fast as every 10 seconds depending on plan
Battery Up to 2 weeks at 1-minute updates
Magnet Waterproof magnetic case sold separately
Coverage USA and Canada
Subscription From $19.95/month, higher tiers for faster updates
Included SIM and data plan
Certification FCC certified
Optimus tracker, angle 1

Pros

  • Small enough to place where a larger unit won't fit
  • Case survives repeated car washes
  • Up to two weeks of battery at 1-minute updates
  • Custom alerts by text and email
  • Volume discounts across a fleet

Cons

  • Magnetic case is a separate purchase
  • Subscription required for the device to work at all
  • Battery life drops sharply at faster update rates
  • Feature tiers are aimed at fleets, not single vehicles

4. Tracki — Cheapest Way Into Vehicle Tracking

Tracki mini GPS tracker

Tracki Mini GPS Tracker

  • Global real-time tracking with a worldwide SIM included
  • Tiny and light, with a magnetic waterproof case available
  • Up to 60 days in battery saver mode

4.2 stars from 46,041 Amazon ratings

Buy on Amazon Watch a video review

Tracki is the best-known name in consumer vehicle tracking and one of the top-selling GPS trackers on Amazon. If you want the lowest possible cost of entry in a magnetic vehicle tracker, this is it.

Being the most popular isn't the same as being the best. Tracki is light, genuinely tiny, and cheap to buy, and it runs up to 60 days in battery saver mode.

The trade-offs show up when it matters. Update intervals are slower than the units above it on this list, and accuracy is looser. For low-stakes jobs — knowing roughly where a trailer or a bike is parked — that's perfectly adequate, and the price is hard to argue with.

For recovering a stolen vehicle, or anything where a five-minute-old position isn't good enough, spend more. Its Amazon rating sits at 4.2 across more than 46,000 reviews, and the critical ones cluster around exactly this: the location wasn't current when the owner needed it to be.

Spec Tracki Mini
Size 1.8 x 1.6 x 0.7 in
Weight 1.26 oz
Battery 2–5 days active, up to 60 days in saver mode
Magnet Magnetic waterproof case sold separately
Coverage 4G LTE plus 3 bands, worldwide SIM included
Subscription From $9.95/month
Warranty Lifetime
Tracki tracker, angle 1

Pros

  • Lowest hardware cost on this list
  • Smallest and lightest unit here
  • Worldwide SIM included
  • Plans from $9.95/month
  • Lifetime warranty and 24/7 support

Cons

  • Slower updates than the trackers ranked above it
  • Accuracy is looser than the premium units
  • Magnetic case is a separate purchase
  • 2–5 days of active battery means frequent charging
  • Subscription required
Positive Review
★★★★★

Amazon customer, April 2024

A cyclist using it on a bicycle singles out the geofence feature and describes support as quick and helpful when they had questions.

Another reports the unit freezing on a stale position for four to five hours at a stretch, which they found made it unusable.

5. Spark Nano 7 by BrickHouse Security — Best Panic Button

Spark Nano 7 GPS tracker

Spark Nano 7 by BrickHouse Security

  • 4G coverage across the US, Canada, and Mexico
  • Built-in panic button, rare at this size
  • Durable in cars, trucks, and motorcycles

4.4 stars from 598 Amazon ratings

Buy on Amazon Also at Best Buy

The Spark Nano 7 is a capable mini tracker for a single car or motorcycle. BrickHouse Security is one of the better-known names in the category, with solid support behind it.

The app is easy to use and gives you 30 days of location history, which is genuinely useful for reviewing where a vehicle has been over the past month.

The panic button is the feature that sets it apart at this size — useful if the tracker is riding with a family member who might need to signal for help.

Two things to know. The magnetic waterproof case is not included — it's a separate purchase at around $13, which matters in a roundup of magnetic trackers. And the default reporting interval is 60 seconds, with a faster "Rapid Track" mode available, so it isn't competing with the 3-to-5-second units above.

Spec Spark Nano 7
Update speed 60 seconds by default, faster on Rapid Track
Accuracy Approximately 8 feet
Battery 2600mAh, rated up to 15 days
Magnet Magnetic waterproof case sold separately, around $13
Size and weight 3 x 1.58 x 1 in, 3.3 oz
Coverage 4G LTE across the US, Canada, and Mexico
Extras Built-in panic button, 30 days of location history
Spark Nano 7, angle 1
Spark Nano 7, angle 2
Spark Nano 7, angle 3
Spark Nano 7, angle 4

Pros

  • Built-in panic button, uncommon in a unit this size
  • 2600mAh battery rated up to 15 days
  • Established brand with real support behind it
  • 30 days of stored location history
  • Sold through mainstream retailers as well as Amazon

Cons

  • Magnetic case costs extra, around $13
  • 60-second default reporting is slow next to the top picks
  • At 3.3 oz it's heavier than most units here
  • Subscription required
  • Few standout features beyond the panic button
Positive Review
★★★★★

Amazon customer, March 2024

A buyer praises both the setup instructions and the support rep who handled their questions within minutes, and reports the device working reliably on daily checks.

6. Family1st LTE — Best Pocket-Sized Tracker

Family1st portable GPS tracker

Family1st Portable GPS Tracker

  • Live tracking with updates as often as every 5 seconds on 4G LTE
  • Compact and quiet, with no lights to give it away
  • Geofence zones with speed and movement alerts
Buy on Amazon Also direct from Family1st

Family1st is a small tracker suited to family vehicles and to keeping an eye on relatives who've agreed to it, since it reports speed, location, and movement in detail.

You can set geofences and get several types of alert whenever a vehicle leaves them. It goes further with speed notifications, color-coded speed bands, and trip replays for reviewing how a vehicle was driven across a day.

The hardware is the cheapest here at around $15, which is the main reason to consider it. Two caveats: the magnetic case is a separate purchase, and stored location history is capped at 30 days, which is shorter than most of this list.

Spec Family1st
Update speed As often as every 5 seconds
Battery Roughly 1–2 weeks active, up to 6 months standby
Magnet Magnetic case sold separately
Size 2.8 x 1.8 x 1.1 in
Location history Capped at 30 days
Subscription $15.95/month on an annual plan, $21.95 month-to-month
Support 24/7 email, plus weekday phone support
Warranty Lifetime

  • Compact at 2.8 x 1.8 x 1.1 inches
  • Up to 6 months of standby battery
  • Detailed speed bands and trip replay
  • Lifetime warranty, plus phone and 24/7 email support

Cons

  • Magnetic case is a separate purchase
  • Location history capped at 30 days
  • Active battery life is closer to 1–2 weeks than the standby figure
  • Subscription required despite how it's sometimes advertised
  • Email support can take 24–48 hours to respond

7. Amcrest GL300W — Best Alert Options

Amcrest GL300W GPS tracker

Amcrest GL300W GPS Tracker

  • Tracks vehicles and valuables across the USA, Canada, and Mexico
  • Up to 14 days on a charge, depending on update speed
  • Alerts for zone entry and exit, speeding, and stops

4.2 stars from 2,006 Amazon ratings

The Amcrest GL300W is small, portable, and built for everyday monitoring of a vehicle or mobile asset. It has some of the best alert options we tested, including speed notifications, harsh-braking alerts, and proximity alerts.

Battery lasted 10 to 14 days across our testing, and support resolved our issues quickly. It held up well for the price — solid, if nothing exceptional.

Spec Amcrest GL300W
Update speed Adjustable, as fast as every 5 seconds
Battery 10–14+ days at 60-second updates
Magnet Weatherproof magnetic case included

8. LandAirSea 54 — Best Long-Standby Asset Tracker

LandAirSea 54 GPS tracker

LandAirSea 54

  • Long standby life that outlasts most of this list
  • Strong built-in magnet with no case to buy
  • Manage multiple trackers from one account

4.5 stars from 25,437 Amazon ratings

Buy on Amazon Watch a video review

The LandAirSea 54 is our pick when a tracker needs to sit on something for months at a time without anyone touching it — a trailer in a yard, a boat on a mooring, seasonal equipment in storage.

Power-save mode is what earns it that spot: up to six months between charges, well beyond anything else here. Alerts are quick and location updates hold up when the device is reporting actively.

The 54 is also small enough to travel with a person rather than a vehicle — in a bag or a coat pocket — which suits keeping in touch with an elderly relative or a family member who knows it's there and wants the reassurance. LandAirSea's customer support is among the better operations in this category, which matters most in exactly that situation.

Spec LandAirSea 54
Size 2.275 in diameter, 0.945 in tall
Battery 1500mAh rechargeable; up to 6 months in power-save
Magnet Built into the case
Operating range -40°C to 60°C
Network 4G LTE with satellite assist
App SilverCloud, multiple devices on one account

The 8 best magnetic GPS tracking devices compared

Finding a Magnetic GPS Tracker on Your Car

Think there's a tracker on your car? Start with a slow, thorough look over the vehicle and check the places these devices usually end up.

Common hiding spots:

  • Underneath the vehicle — where most magnetic trackers attach, especially wheel wells and frame rails
  • The OBD-II port — under the steering column, a common spot for plug-in units
  • Beneath the seats or in the trunk — take a flashlight to both
  • The glove box and center console
  • Inside the dashboard — worth a professional inspection rather than pulling trim yourself
  • Behind or under the bumpers

Can't find anything by hand? A GPS detector can help, reacting when it picks up a transmitting device much like a metal detector reacts to metal.

If you find a tracker you didn't put there, don't assume you know who placed it. Photograph it where it sits before you touch it, and contact local law enforcement — unauthorized tracking of a person is a crime in many states, and the device itself is evidence. Removing it first can destroy the only proof you have.

Where a GPS tracker is commonly hidden on a car

Legal and Ethical Considerations

Laws on tracking a vehicle or a person vary by state, so check yours before you place anything. As a general rule, tracking a vehicle you own outright is legal. Beyond that, the picture changes quickly.

If you're an employer tracking company vehicles, tell your drivers. Several states require advance written notice, and a documented policy protects you either way — our sample GPS tracking policy covers what to include.

Where the line actually is

Placing a tracker on a vehicle you don't own, or using one to follow a person who hasn't agreed to it, can bring criminal charges and civil liability. Several states have dedicated criminal statutes covering the installation of tracking devices without consent, and several more treat it as stalking or unlawful surveillance.

Tracking a spouse, partner, or ex without their agreement is not a grey area, whatever the situation behind it. If a vehicle is jointly titled, whether you count as an owner for these purposes varies by state, and during a separation or divorce it can damage your own legal position regardless of the title.

If you're unsure whether your situation is covered, talk to an attorney in your state before placing a device. For general background, see our guide to GPS tracking laws. This is general information, not legal advice.

Frequently Asked Questions

Do all GPS trackers have magnets?

No. Some, like the SpaceHawk and LandAirSea 54, have the magnet built into the case. Others — including Tracki, SpyTec GL300, Optimus, Family1st, and the Spark Nano 7 — are sold as bare units and need a magnetic waterproof case bought separately. That extra case is easy to overlook when comparing prices, and on some models it adds meaningfully to the total.

Is it legal to use a GPS tracking device?

Buying and owning one is legal. How you use it decides the rest. Tracking a vehicle you own is generally legal, including company vehicles, though several states require you to give employees advance written notice.

Using a tracker to follow someone without their consent can be a crime, and that includes a spouse's car. Check your state's law before placing a device, and see the fuller note above.

Will a magnetic GPS tracker fall off my car?

Generally no. These use neodymium magnets, which hold firmly to clean, flat steel. Magnet strength does vary with the surface — a thick layer of undercoating, rust, or a non-ferrous panel all weaken the hold — so pick a clean metal spot and give the device a firm tug before you drive off.

Do magnets interfere with GPS signal?

No. GPS relies on radio signals from satellites, which magnets don't affect. What does interfere is anything blocking the view of the sky: underground parking, concrete parking structures, and dense downtown areas where tall buildings create urban canyons. Placement matters far more than magnetism.

Which magnetic tracker has the longest battery life?

The LandAirSea 54, at up to six months in power-save mode, followed by Tracki at up to 60 days in saver mode. Both figures assume infrequent reporting — switch either to live tracking and you're back to days rather than months. If you need both fast updates and long life, that trade-off is the thing to plan around.

Where We Stand

GPS Tracker Shop sells the SpaceHawk tracker ranked first on this list. We're saying so plainly because it should shape how you read that ranking.

SpaceHawk is the tracker we stock because of how it placed against a long list of portable trackers we've tested, on the two specs this category lives or dies by: how fast it reports and how close the reported position is. It isn't the cheapest here, it has a smaller battery than several rivals, and if you need six months of standby on a trailer sitting in a yard, the LandAirSea 54 at number eight is the better buy — which is why it's on the list.

The other seven are other companies' products. Amazon links throughout are affiliate links, meaning we may earn a commission at no extra cost to you, and they don't affect which product wins a category. Specifications come from manufacturer documentation and current retailer listings.

Want the fastest, most accurate option here?

SpaceHawk reports as often as every 3 seconds, lands within about 6 feet, and the magnet is built into the case — nothing extra to buy.
