Summary: I am not a hunter, so a lot about this set up is over-kill for me, but it was the only system I could find that I felt confident taking into the woods where there is no cell phone signal. I also don't use the shock function at all and took the shock prongs off.
Summary: I have four of these and will not hunt without them again. Know where my hounds are at all times and can correct when needed. Hounds now respond to tone and I rarely have to use the shock anymore.
