Based on my experience, I have never dry fired a bow using camo with the trade mark of Scent-Loc. I have busted the thing up while playing dress up in No Trace. I will say the the No Trace is cheap vs. any of the others. I have no idea if it works or not but what the heck, I do look good in it. Geez.. It's like you can't show your soft underbelly in here.
