Hey Zwa,
Let me know what you think of those lights. I've been looking at them but I'm not sure if they are good or not. I've done alot of work with the tri-beam and the green is really bright, So I imagine the emerald scan is bright also. They should be relatively easy to program. The problem the tribeam has when programming is it won't stay on continuously so you can see where it is aimed. It will come on for about 2 seconds and then go off. I'm not sure if the emerald scan has the same problem. If it doesn't, it will be an awesome thing. I know this was long winded, sorry
