Stability for outdoor viewing an often overlooked aspect to daylight and outdoor projector use is the stability of the projector.
Laser you can see in daylight.
So one device s laser brightness is pretty much the same as another.
Lasers red or green are for dark targets in marginal light.
I find them highly effective for target shooting but it s easy to depend on them rather than good sight alignment and control.
Neither is visible enough in daylight for rapid acquisition.
Laser distance measure generally has a laser output of less than 1mw class 2.
You don t want to tear it apart unless the manufacturer says to so be sure to only gently wipe down the parts you can easily see.
It s basically the same principle used by the laser card but instead of creating a light filter in a small localized area it creates a light filter across your entire field of vision.
