Well, Rube is a runner. He runs in a direction, gets on a scent and just goes. Usually, he goes where he shouldn't. Once he runs the "stink" off he is more responsive.
I need something to get his attention. Looking for a shock, sound, vibrating collar. 300+ yard range. Adjustable stimulations. Water proof is a plus. Not going swimming but snow and rivers. Cost is a factor (under $50). Older eyes need easy to read remote controls.
Ideas?
TIA!
