Overall, the battery-based units don’t monitor driver performance as well as plug-in GPS trackers due to the reduced power supply and the need to recharge batteries (communicating with GPS and data satellites requires a good amount of electricity). Instead, they get their power from either rechargeable internal or removable batteries and are often fixed to vehicles by way of magnets or a special case designed specifically to be hidden out of sight somewhere on the undercarriage of a vehicle.

Like their conventional counterparts, the concealable types perform all the same functions, only they don’t rely on being plugged directly into a car’s onboard diagnostics or OBD-II port.

Whether you’re a concerned individual looking after a loved one or a commercial entity looking to make sure your fleet of vehicles aren’t being abused, hidden GPS trackers could be particularly useful if discretion is a must and tampering is a concern. While most conventional units plug directly into and run off a car’s on-board diagnostics and computer port, more discreet and hidden GPS trackers exist in case one needs to keep a secretive eye on vehicle assets. These days, being able track a vehicle’s location as they drive in real-time is a rather easy and affordable affair thanks to traditional GPS trackers.
