OT question on laser diodes / visibility in sunlight
Being a lousy golfer, thought I'd put a laser on my putter,
maybe a line type, for aiming and more importantly, straightness.. The 4 milliwatt red ones don't show up, how are the higher power ones, green ones etc., anyone tried? /thanks / mark the duffer |

If you just need to see the dot, you should do ok with a green one. 15mw should do. |

(no joke- they do make 'em) Or, you could take the write head out of an 8x or better DVD burner and put a collimater on it. Its a kick-ass red LED laser, but it will set the grass on fire (not kidding again!) and will blind people in the beam instantly. Dave |

(snip) Not sure what shade of green the green laser diodes are but how well would green show up on the green?. 532nm. And if it is dark enough to show the path, it will be dark enough the color of the grass won't really matter. |
