That's a simple and effective looking paper tuning rig Hutch. I may make one like that out of my Ladder Golf game things. Haha
Thanks its cheap and so am I ha! ha! But a cheaper way is to use a big TV box and cut a square out of it and tape wrapping paper over it.
I use a cardboard paper box with a 7.5"x10" hole cut in the bottom. I tack a sheet of paper over the hole & presto, I'm paper tuning.
I shoot about 9 feet away to see how the arrow is released from the bow. Then I move back to 10yds then 20yds and make adjustments.
