The freedom to track a vehicle’s location in real-time, without wires, tools, or permanent installation, has revolutionized how we protect and manage vehicles. That’s the beauty of a magnetic GPS tracker for cars. It’s portable, powerful, and incredibly easy to use.
Whether you’re a small business owner managing a fleet, a parent watching over a new driver, or just trying to protect your investment from theft, magnetic GPS trackers offer reliable location tracking with zero technical hassle. And after nearly two decades of testing GPS tech at BrickHouse Security, I can confidently say: magnetic trackers are one of the most effective and flexible tracking tools available today.
In this guide, I’ll walk you through everything you need to know, how they work, where to place them, what to look for, and how to use them responsibly.
What Is a Magnetic GPS Tracker?
A magnetic GPS tracker is a portable, battery-powered device that attaches to the exterior or interior of a vehicle using strong magnets. These trackers:
- Use GPS satellites to determine the vehicle’s location
- Transmit data via cellular networks (like 4G LTE)
- Are accessed and controlled via a smartphone app or web platform
Why the Magnet Matters:
The built-in magnet allows for quick and easy attachment to any metal surface, often under the car or in the wheel well, with no need for wires, installers, or cutting into the vehicle’s electrical system.
Key Advantages:
- No installation required
- Completely portable and reusable
- Perfect for discreet tracking
- Ideal for short-term or temporary use
So whether you want to monitor your teen’s driving habits, locate a stolen car, or track company vehicles without permanent installs, a magnetic GPS tracker is your go-to tool.
Who Uses Magnetic GPS Trackers?
These trackers are more versatile than people realize. At BrickHouse, we work with individuals and businesses alike who rely on magnetic GPS devices to solve real-world problems.
1. Parents of Teen Drivers
One of the most common uses is monitoring teen drivers. Parents can:
- See where their teen is in real time
- Set boundaries like “school” or “home” with geo-fencing
- Get alerts if their teen speeds or strays from expected routes
It’s not about spying, it’s about safety, accountability, and building trust.
2. Car Owners Concerned About Theft
Car theft happens fast, and recovery is difficult unless you know where the vehicle is. A well-placed magnetic GPS tracker helps you:
- Locate your stolen car in real time
- Share coordinates with law enforcement
- Act before the vehicle is dismantled or shipped out of state
Bonus: Many insurance companies now offer discounts for using anti-theft GPS devices.
3. Fleet Managers and Business Owners
Businesses use magnetic GPS trackers to monitor company vehicles without modifying them permanently. These trackers help:
- Optimize routes and reduce fuel costs
- Monitor unauthorized vehicle use
- Track deliveries and on-site visits
Since the trackers are portable, they can be moved between vehicles, ideal for rotating fleets or temporary contractors.
4. Investigators and Law Enforcement
When used legally and with proper authorization, magnetic GPS trackers are a powerful surveillance tool. They’re used by:
- Licensed private investigators
- Law enforcement with proper warrants
- Legal professionals conducting court-approved surveillance
Important Note: You must own the vehicle or have consent to use a GPS tracker. Tracking someone else’s car without permission is illegal in many jurisdictions.
Key Features to Look For in a Magnetic GPS Tracker
Not every GPS tracker is up to the job. Here’s what I recommend based on years of field testing and customer feedback.
1. Strong Magnetic Mount
The magnetic case should grip tightly to the vehicle, even at highway speeds or over bumpy roads.
Look for:
- Industrial-grade magnets (80 lbs or more holding force)
- A weatherproof housing to protect the tracker from road grime, rain, and snow
- A low-profile shape to stay hidden under the car
If the magnet is weak, it won’t stay attached, and you may lose the device altogether.
2. Real-Time GPS Tracking
Real-time tracking gives you the ability to:
- See exactly where your vehicle is right now
- Get updates as frequently as every 5 seconds
- Monitor trip history and detailed routes
Make sure the tracker uses 4G LTE or better for fast, reliable data transmission.
Real-time updates are essential for:
- Quick recovery in case of theft
- Monitoring teen or employee driving behavior
- Instant alerts when something’s not right
3. Long Battery Life
Battery life is one of the most important considerations.
Here’s what to expect:
- Standard magnetic trackers: 7–10 days
- Extended battery models: 30–60+ days
- Power-saving settings: Up to 6 months, depending on how often the tracker updates location
Look for features like:
- Battery level alerts
- Sleep modes to conserve power when not moving
- Magnetic charging cases for easy recharging
Todd’s Tip: Always charge before long trips or missions, and check your app for battery levels regularly.
4. Geo-Fencing and Smart Alerts
Geo-fencing allows you to create virtual boundaries around:
- Home
- Work
- School
- Construction sites
- Delivery zones
If the vehicle leaves or enters these zones, you’ll get an instant alert.
Other smart alerts you’ll want:
- Speeding notifications
- Start/stop movement alerts
- Low battery warnings
- Tamper alerts (if someone tries to remove the device)
These alerts turn your GPS tracker into a full-featured safety system.
5. User-Friendly App and Web Dashboard
You shouldn’t need a tech degree to use your tracker. Look for an app that’s:
- Easy to install
- Simple to navigate
- Packed with features like trip history, map views, and alerts
Bonus points for:
- Multi-device support (track multiple vehicles at once)
- Cloud-based access from any device
- Secure data encryption for your privacy
Where to Place a Magnetic GPS Tracker on a Car
Choosing the right placement ensures the tracker:
- Gets a strong GPS signal
- Stays securely in place
- Stays hidden from view
Top Recommended Locations:
- Under the rear bumper (plastic covers don’t block GPS signals)
- Inside the wheel well, away from moving parts
- Under the chassis on a flat metal surface
- In the trunk, especially if the lid is not fully metal
- Under seats or inside glove compartments (for internal use)
Avoid placing it directly on thick metal shields or near heat sources like the muffler or engine.
How to Test Placement:
- Attach the tracker and drive around for 5-10 minutes
- Open the app and check for location accuracy and signal strength
- Adjust placement if needed

Magnetic Tracker vs. Hardwired Tracker
| Feature | Magnetic GPS Tracker | Hardwired GPS Tracker |
| Installation | No tools required | Requires wiring into the vehicle |
| Power Source | Internal battery | Constant power from the car |
| Portability | Easy to move between vehicles | Permanent install |
| Visibility | Can be completely hidden | Usually inside the dashboard |
| Best Use Case | Short-term, flexible tracking | Long-term, permanent tracking |
If you want flexibility, the magnetic option wins. But for permanent fleet tracking or power-unlimited installs, hardwired trackers are a better fit.
Is It Legal to Use a Magnetic GPS Tracker?
The short answer: Yes, when used correctly.
Legal Uses:
- Tracking your own car
- Tracking a vehicle your minor child or employee is using (with notice)
- Using GPS to protect company assets
Illegal Uses:
- Tracking a vehicle you don’t own without permission
- Using GPS tracking in a stalking or harassment context
- Tracking someone without their knowledge (in most states)
Check local laws in your state or speak to a legal professional if you’re unsure. We always recommend using GPS technology ethically and legally.
