Rob, often times the thieves simply tear apart the units in hopes of finding wire and other recyclables. this is sad.
Also, equipment is still heading to mexico, maybe if authorities see it they can nabb it for you at the border. tough call, with unemployment here, folks are returning to Mexico in droves.
Unfortunately authorities consider survey grade GPS units as something not worthy of much concern.
Our military uses GPS to pinpoint a missle thru a 2'x4' window in Baghdad.
worthless stuff indeed !
good luck my man.
My stolen GPS went to tweekers who simply smashed them for the wire ??
