Cool! I've never used one but I can see in the right places it would be handy to have...
Wondering...If a guy drilled larger holes on one side of the center ridge, and also cut a long open curved slot about 1" wide and 6" long right along the bend at the barrels side...?...
Then, a guy could do the initial scoop dump on the small side, rake or shake the large over to the other side of the ridge for more to fall through, find your target with a pinpointer or by eyeball...then, simply swipe or shake all the debris right out through the slot, a fellow would not have to be dumping it out all the time? It would be sort of like a big gold pan dealie? I dont know...just thinking..
Probably be best to try one out with the small holes and then modify if needed to suit the areas a guy hunts plus the scoop holes a guy uses...can always go back and drill some larger holes later...
