This is an alternative to a buried wire. Instead of getting a warning sound/shock when he gets to close to a wire, this goes off if he gets too far from a central point. I've never used either one so can't tell if they work. I just thought this might be easier to install than digging a trench around the yard.
Edit: is this the same Instant Fence you mentioned? This one specifies
no underground wires required.
