im wondering if any body has left there foxpro out over night as to come into a location and start calling with out the initial set up noise and movement. ive got a spot i want to call but the best place for the call will require making some noise and alot of movement to set up. im not worried about it getting stolen the areas well of the beaten trail, but will my batteries be dead in the morning? i have the FX3 so i cant turn it on or off with the remote. does the foxpro go into a sort of "sleep" mode?
