I received a package today with what is called A-ACiD (the i in ACiD is my contribution to acryonym death). My first thought was Disappointment
Why you ask? Because I'm making them myself this unit is so vastly superior to mine:(
I can't justify the effort to make any more, I'll be ordering more. I have the $30, $35 and $40 comerical units too, but I can't see spending that much for every scope.
Caviet: The pic is not mine. I hope to do some testing with some of my bigger cannons after the 4th.
You can get the *straight skinny* on these from This thread
