I've used the M-80TR (by the same company), but not with comparable results
a T68 marker with a 16 inch rifled barrel, a Q-loader, a harris bipod, a 4x32 tasco scope and BSA laser sight attachment and last but not least a gas thru stock complete with remote line.
Definitely the versatility of the mine and the trigger sensitivity make it a useful tool
The unnatural pipe shape makes it stand out in the underbrush
I've found that this mine becomes even more useful in the field with some modifications. if you hot glue the trip cord to the wheels of a small remote control car, then you can paint it brown and leave it upside down near the mine. then you can use the remote for the car to trigger the mine by pulling the accelerator trigger. it's crude but it gives you a much safer distance to trigger it from.
I definitely recomend this product for woodsball players and field owners with a decent amount of land. it really puts a little more strategy in the game and it helps to nail the guys who spray thier automatics while walking in a straight frigging line at your bunker.
