Asset tracking devices are increasingly being used to track a wide variety of assets, including bags, computers, equipment, containers, truck trailers, and other expensive items. GPS asset trackers come with a large battery and a strong magnet for fast and easy installation. There are two types of GPS asset tracker installation: magnetic and normal. Magnetic installation refers to asset trackers that are equipped with magnets for easy attachment to iron surfaces such as under vehicle chassis. The magnets are strong enough to stay in place even on bumpy roads. Normal installation refers to small asset trackers that can be hidden in bags, wallets, pockets, or on people. They are usually much smaller than magnetic GPS trackers. Model B28 comes with a separate magnet, making it a mini gps magnetic tracker. Spy Tracker PG10 also has a built-in strong magnet.
