Since the inception of GPS Tracking and Fleet Tracking, there has not been a unit that can provide large fleet trailer owner with the reliable tracking and scalable management of their trailer fleet.Battery life has long been the Achilles heel of the trailer tracking unit. Many units were very reliable, yet the battery life would last only a few days to a few months. Some even tried solar power units in an effort to breach this gap in the trailer tracking oasis.One unit now claims to have battery life of up to ten years. TEN YEARS!!! With full online reporting and 6 updates a day, this unit bridges the gap of functionality and form. This seems to be an answer to the long awaited question, How They Do That? The unit is very compact and low in profile. 6.3” X 9.2” X 1.77”. It can be fitted on any trailer, either vertically or horizontally.
