What Is a Hidden Magnetic GPS Tracker?
A magnetic GPS tracker is a small, battery-powered device that clamps to any metal surface on a vehicle or asset using built-in magnets. It uses GPS to pinpoint its position and a mobile SIM to send that location to an app and online mapping panel, all in real time and with full journey history. Because there is no wiring, you can fit it in seconds and switch it between vehicles whenever you need to. That flexibility is what makes it so popular for cars, vans, trailers, plant and other movable assets.
Our Best Magnetic GPS Trackers
Best for Battery Life: Pro Micro Magnetic
The Pro Micro is our most popular magnetic tracker. It combines small dimensions with an impressive up to 12-month replaceable battery, so it will attach magnetically to a vehicle or asset and stay put until you are ready to remove it. If you want a device you can hide and largely forget, this is the one. View the Pro Micro Magnetic.
Best Value and Smallest: Micro Magnetic 4
The Micro Magnetic 4 is our most cost-effective tracker and, quite frankly, the cheapest at this level. Small, lightweight and covert, it has the same core tracking features as the rest of the range. The main difference is battery life, at 10 to 15 days between charges depending on usage, so it suits anyone with regular weekly access to charge it. It is also the smallest option: around 75 x 50 x 60mm in its magnetic case, or just 70 x 40 x 20mm out of the case, though used outside the case it is no longer fully waterproof. Two ultra-strong neodymium magnets give a combined 60kg pull, and the multi-roaming SIM switches networks automatically across Europe and beyond at no extra cost. View the Micro Magnetic 4.
How to Choose a Magnetic GPS Tracker
The right tracker depends on how you will use it. Weigh up these factors:
• Battery life vs update frequency. More frequent live updates drain the battery faster. If you need second-by-second tracking, expect shorter battery life or choose a longer-life model like the Pro Micro. If occasional updates are enough, the battery lasts far longer.
• Size. Smaller devices are easier to conceal. The Micro Magnetic 4 is the most compact.
• Magnet strength. A strong magnet keeps the device in place under a moving vehicle. Ours use neodymium magnets with a heavy pull.
• Waterproofing. For external placement you need the waterproof magnetic case. Used out of the case, a device is only suitable for a dry, internal spot.
• Coverage and contract. A roaming SIM keeps you connected abroad. Our trackers run on a small subscription with no fixed contract.
Where to Attach a Hidden Magnetic Tracker
There are several good spots for a covert tracker:
- Flat metal on the chassis
- Front bumper
- Rear bumper
- Under a seat
- Inside the glove box
- Seat pocket
- Inside the boot, near a window
Metal can weaken the GPS signal, so avoid fully enclosing the device in metal, for example a boot with no window. Tip: check the signal strength on your mapping panel before settling on a final position. For a full breakdown, see our guide on where to hide a GPS tracker in a car.
Is It Legal to Use a Hidden GPS Tracker?
Yes, when you own the vehicle or asset. If family members or employees also use the vehicle, you should tell them a tracker is fitted. Placing a tracker on a vehicle you do not own, or using one to track a person without their knowledge, is illegal. Used properly, a hidden tracker is a responsible way to protect your own property from theft.

Frequently Asked Questions
What is the best hidden magnetic GPS tracker for a car? It depends on your needs. For the longest battery life and a fit and forget device, the Pro Micro Magnetic is our top pick. For the best value and smallest size, the Micro Magnetic 4 is ideal if you can charge it regularly.
Do magnetic GPS trackers need installation? No. They attach to any metal surface in seconds using built-in magnets, with no wiring. You can also move them between vehicles whenever you like.
How long do magnetic GPS tracker batteries last? Anywhere from around 10 to 15 days to up to 12 months, depending on the model and how often it reports its location. Frequent live updates shorten battery life.
Are magnetic GPS trackers waterproof? In their magnetic case, yes, which is what allows external placement such as the chassis or bumper. Used out of the case, a device is smaller but no longer fully waterproof, so keep it to a dry internal spot.
Is there a monthly fee for a magnetic GPS tracker? There is a small subscription covering the SIM data and the tracking platform, but no fixed contract.
Is it legal to use a hidden GPS tracker? Yes, on a vehicle or asset you own. If others drive it, you should tell them a tracker is fitted. Tracking a person, or a vehicle you do not own, without consent is illegal.
