Buddha, even us "smart" ones do things like turn the dogs loose without taking the magnet outta the tracking collar or turning the shocking collar on or having the collar too loose or not checking to see if the antenna is tight, the unit is secure to the collar, etc. etc. etc. I've done all of the above at one time or another
! Just common things even the vetrans need reminded about from time to time. It is frustrating when you get something that should be dependable and yours is the one that ain't. Good luck with it and good hunting. Paul Conway.
