If you count your time and fuel costs (along with your materials and tools).....what have you really saved?
I guess $72 a dozen. Assuming lumenocks cost $9 a piece, that you have the tools, and that you pickup the materials while you're already at the store shopping for other things.
Never really used either. But I do know that they may come in handy. The other day I wasshooting at the club at a Buffalo Target at about 60 yards over a ravine. Couldn't see where the arrows were impacting from where I was standing.
