Here's a functional way to use an old optical chronograph and a old satellite dish bracket.
I mounted the chronograph to the bottom by installing one 1/4-20 bolt. I place a white tarp or towel on the ground for better results. Now, I can shoot through the lights at any range. Surprisingly, my little 50# Whistler is slinging my hunting weight broadheads through there at 165fps @ 30 yards. The uukha is doing a little faster...lol. I still prefer the Whistler.
