With the purchase of the waterproof, AM-GL300W-4G case, you not only protect your tracker from unavoidable impact and water exposure, but also improve its functionality. The case lets you firmly anchor the tracker to any metallic surface, including above or below your vehicle. *This high quality weather resistant magnetic case is made for our Professional Grade Portable GPS Tracker (AM-GL300W-4G). * *GPS Tracker Sold Separately.
