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.
Can you see laser sights in daylight.
You can bring a laser into play and in perfect alignment with the target much faster and with less effort than you can iron sights if you want to.
But when one is using in the daylight and would like to see the clear hands of the target you must prefer the red dot for the perfect shot.
While they certainly make it easier to aim in low light situations if you can t make out your target with iron signs a laser sight isn t going to make it any brighter.
In the low light photo you can see some speckling in the green dot which occurs when the laser s lens gets dirty.
So yes you can technically use any laser distance measure outside but depending on the distance you want to measure they may do what you want them to do.
For daylight the best front sight for rapid acquisition is a fiber optic trijicon hd or possibly a gold mcgivern bead.
Outside in full sun you will not be able to see the laser dot more than about 10 or so meters 30 feet.
The photos were taken with the lasers about 10 feet from the target.
There s a common misconception that laser sights help you see better in the dark.
If you want to see a red laser in sunlight you have.
But we would recommend that while going for the low light shot you must go with the green dot which might be more useful for you in the caves to see the enemy.
That s closer than i shot the drills but my camera can t see the laser as well as a human so the lasers had to be moved in for the pictures.
