I don't think it would work for me as I shoot outdoors. The "range" is dirt with rocks and trash that would get picked up too. Same with the "nut collector", I'd get 10% brass and 90% rocks and shotgun shells. So to save my back I made my "case picker upper". I used an old squegee telescoping handle and a piece of spring steel rod, 1/8" dia, tapered and 1" or so, bent 90 degrees. attached the rod to the "working end" of the handle and it telescopes down to about 36" and lives in the bed of my truck. I walk around and "hook" brass and deposit it in a coffee can in my other hand. A broom stick with a rod stuck in one end will work just as well...
