What they call a spear I call a gig. When I was young we would go frog gigging at night in the swamp. One would shine the light and find the frog and the other would circle around and come up from behind an gig the frog.
As for the gun, it sounds strange to me. I can hear it now, "I am going fishing dear, where is my 30-30?" Next thing will be "I am going deer hunting, where is my Shimano rod and reel?"
