This is very simple to do and results are great!
You need two pieces of 1x2 or 2x2, 7 inches long and one thin piece of molding. :-
Drill a hole on each end of the 1x2's for a large nail, slip fit.
Attach the small molding perpendicular to one 1x2 in the center.
Attach a wire to the center of the other 1x2 with a screw, large head.
Attach a wire to the end of the molding with a small bolt.
Attach the other ends of the wires to a PF284 PowerFlash, Mode 3.
Place the 1x2 with the wire in the center, across a Mole tunnel, push nails down on each side to secure.
Place the other 1x2 with the molding adjacent to the 1st. and secure with nails
The contacts, the screw and bolt, must line-up and be 1/16 inch apart.
Program your AHP or whatever to sound the Mole action alarm.
When the alarm is triggered, go outside, where the ground is moving, and stomp him
Dig it up and toss................
