RE: laser sight for bow
Then I'm going to guess it would be illegal depending on the state you live. I would for sure check the regulations.
And like I said I don't think it would work very well, maybe for poaching them at night, but I'm not sure because of the color and type of fur on a deer. Never pointed a laser at one to be honest.
My opinion after using laser sights on some different weapons is they work pretty well for what they were designed for, shooting people in low light at close distances when you can't aim properly for one reason or another. Other than that I really don't see where they give you that much of an advantage.
Also keep in mind that a twig, leaf or certain weather conditions could keep the beam from making it to the animal.
