No reason to buy dodging tools (buying dodging tools are a waste of money), make your own. How? Take a wire twist-tie with paper, burn off all the paper except for 1/16" (or 1/8") and start with that. The wire itself will never create a shadow so it's almost foolproof. Or maybe a tooth-pick, Q-tip, Tootsie Pop stick, harder then a twist-tie but still works. The main thing is keep the stick as small as possible.
