Hello from cape cod! This is Jims19 and would like to know what is the most powerful laser. Green, red,etc. available retail say from a store that sells such items. From what I understand, the 5mw type is very weak. Im looking for power., for use in sighting game from long distances. I have worked in ophthalmology with all types of medical lasers. What do you think as far as store bought? Thanks very much and for welcoming me on board.
