can you see the laser in the sun light outside, that is my main concern.
BILLY on Feb 5, 2015
BEST ANSWER: No you can not see the lazer beam in sunlight with naked eyes further than a couple of feet. However, you do not need to see it since your receiver would detect it for you. You can see the lazer indoors and also in low light outside.
