Guys, I am new to lasers. I am wanting a laser that I can carry when squirrel hunting. This will be used to point up into trees during daylight hours. I need something that can be seen by others. I often hunt in pairs and it will be useful to be able to show my hunting partner where in the tree I last saw the squirrel . I was thinking a green laser for visibility. Can anyone help shed some lighT on this. What power laser would I need, etc? Thanks in advance.
