I just finished fabricating (4) more electronic targets, gopher, squirrel, rabbit and bird. A couple other members asked for more details on them. They are self-contained powered with (4) AA batteries. No need to level them and no reset cord. A fairly clean hit on the head kill zone turns on a set of high intensity red leds, a hit on the body kill zone turns on a set of high intensity green leds. The leds stay on for approximately 2 seconds and turn back off.
