Actually, just a little wider than normal 10mw laser pointers would be enough.
Trees maybe 7-15 meters tall. I would like the lasers can be see a dot in the bright-and-sunny day. would it be possible? :cryyy:
I have bought two laser pointers in the past and both have too thin/narrow
a beam for my purpose. I am a biologist and we use these for highlighting tree
positions for animal/bird watching.
I need 10mw power, colour green, that can be seen in daylight, and has a good 'relatively wide' beam...
