A good shocking collar will get that far easy. If they kept breaking on you it wasn't a deer. They could have been treeing a bobcat they will jump tree when they hear you or see a light coming.
I agree,....if it was a deer they would have been out of hearing in a heartbeat. Shock collar is the best thing for trashing but you better be for dang sure they're on trash before you use it.....I mean as in 'seeing' them running a deer.....not just thinking they are.
x2...same thing with hollering at the dogs to get out when you are not for sure what they are baying/running...
