im not sure how ya could show it but how it works is some fish can see uv colors better then normal and since uv penatrats deeper into the water makes baits show up better at deeper deaths i have been messing with uv stuff last two years and i find they do most days out fish norm colors or the same color none uv

but as in anything theres a but and with uv i belive theres one big one i seem to get more bass on uv jigs then norm jigs and i would say i have gotin more bass in the last 2 years then i ever have i think they see it better then the crappie does
