When i go to focus the beam, i sometimes cant even see it unless i shine it on a white wall then focus it. If i try and focus it on something black, i dont know where the dot is :-?
Is there an easy way to be able to focus on something 15ft away? ( i can barely see it at 1ft away)
so are we talking about ebay lasers in general or just the professional built ones? Cause i got one from there (diode, housing and driver) and its the best one i got right now (i got 3) My ebay one is even better than the Atec red i just bought. Just watch who you buy from is all and their rating.
I got the same thing from Ebay (the same guy too) and i love the pointer i made. Its in a plastic housing for now till i get a wider heatsink made. Its long like that to keep it cool. You can unscrew it and half its size but recommend using another heatsink with it or a TEC. I got it focussed so...
