OPTIMUS GV75 TRACKING DEVICE.   Removed from a drz400S, will work on any bike or enclosed trailer, open trailer, farm equipment etc.  Smaller than a cell phone uses a Cell signal to track and report it's location, requires service from Optimus, but this is one of the few trackers with very affordable service, around 13 dollars per month last time we checked.   Cheap cheap insurance for your items.  It's priced cheap because we already have one, this is a extra one from a bike we purchased.
