I have been lucky enough to have been chosen by October Mountain Products to become their face for the bowfishing world... they have some great archery products and are starting a bowfishing line.. I am working with them to develop some of my ideas along with theirs....
They developed a laser bowfishing sight and this thing really works... it does have a few down falls but none that will effect the average shooter.
One is due to the intensity of the laser it wont work very long in extreme cold weather. No issues with summer use..
although it works better than any other laser tested it still is hard to use during the day although not impossible..
here is a video I did explaining and showing the laser being used
