Hello, Noobie here
I coach high school bowling, and I am looking to use a hand held green laser pointer that I could either purchase or make using a modified laser pointer - It has to be able to make the narrow beam at least 60 feet, the width of the beam no more than 1/2" or smaller. If asking what for.... I use it to show lines on the lanes on how to play certain shots with the bowling ball.
