Magnetic GPS Trackers for Cars, Trailers & Equipment
A practical guide to 4G LTE tracking, magnetic installation, extended battery life and smart location alerts.
Learn how magnetic GPS trackers work, where to install them, and how to compare features and service options before choosing a device.
4G LTE Tracking
Monitor location updates and supported tracking alerts in the TrackerOne app.
Magnetic Installation
Use suitable metal surfaces without permanent vehicle wiring.
Extended Battery
S20 Pro features a rechargeable 7,500mAh battery for extended use between charges.
What Is a Magnetic GPS Tracker?
A magnetic GPS tracker is a portable location-tracking device designed to attach to compatible metal surfaces. It is commonly used for authorized monitoring of cars, trailers and equipment.
Many models use satellite positioning to estimate location and 4G LTE communication to send location information to a tracking app. Unlike a permanently wired system, a rechargeable magnetic tracker can be moved between suitable assets.
GPS positioning and cellular reporting are separate functions. Reliable reporting requires suitable satellite reception, compatible cellular coverage and an active tracking service.
Where Can You Use a Magnetic GPS Tracker?
Choose the device and reporting schedule according to the location, movement and available power of your asset.
Cars & Vehicles
Review reported locations, movement history and supported geo-fence notifications on an authorized vehicle.
Trailers
Keep location visibility on trailers that may be parked for long periods without onboard power.

Equipment
Monitor authorized movement of valuable equipment where a permanent installation may not be practical.
GPS tracking improves location awareness, but cannot prevent theft or guarantee recovery.
How Does a 4G Magnetic GPS Tracker Work?
1. GPS Positioning
The tracker estimates its geographic location using satellite signals.
2. Cellular Reporting
Supported cellular networks carry reported location data according to the device settings.
3. App Monitoring
View available updates, tracking history and alerts in TrackerOne.
How to Install a Magnetic GPS Tracker
Choose a Suitable Surface
Use a stable metal surface with adequate contact. Some panels made of aluminum or plastic are not suitable for magnets.
Check Reception
Avoid locations where thick metal structures may block satellite signals.
Secure the Device
Follow mounting instructions and keep it away from moving parts, hot surfaces and safety-critical components.
Activate & Test
Activate an eligible service plan and verify that the tracker can report its location before relying on it.
Use trackers only on vehicles or assets you own or are authorized to monitor. Obtain any consent required by applicable law.
