GPS trackers (sometimes referred to as 'GPS tags' or 'trackers') are products designed for the real-time location and tracking of cars, karts, vans, motorhomes, buggies, or quads equipped with 12V batteries. Their accuracy is measured in "number of positions sent per second". As a result, Pegase and Flashbird are the most accurate on the market, sending up to 4 points per second. The autonomy of GPS trackers varies according to their internal battery and the use (or not) of the vehicle battery. Pegase and Flashbird are connected to a vehicle's battery, so they are being constantly recharged as soon as the engine is running, which gives them unlimited autonomy, as long as you drive at least twice a month. Size is also an important consideration when choosing a GPS tracker. Pegase and Flashbird are smaller than a credit card, making them "mini GPS" products that are easy to conceal.
