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.
Outside in full sun you will not be able to see the laser dot more than about 10 or so meters 30 feet.
Lasers red or green are for dark targets in marginal light.
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.
I find them highly effective for target shooting but it s easy to depend on them rather than good sight alignment and control.
In some circumstances you may not be able to see it more than 3m 9 feet.
Neither is visible enough in daylight for rapid acquisition.
Laser glasses effectively filter your vision to limit the light you see making it easier for you to identify your laser beam in daylight.
