GPS trackers are known for their high accuracy, which is typically within a few meters. The accuracy of a waterproof GPS tracker is determined by several factors, including the quality of the GPS chip and antenna, the number of satellites in view, and the presence of obstructions such as buildings or trees. However, even with these factors in play, waterproof GPS trackers are generally very reliable and can provide precise location data even in challenging environments.
GPS trackers or similar surveillance devices are often not directly waterproof, but come with protective casing in which they are placed. This casing is waterproof, and in most cases designed to never interfere with normal operation of the tracking device.
