From my understanding fish only pic up and hone in on the UV spectrum during certain life stages so they may not be more effective than any other lure during certain times of the year/for certain species. I added several UV dodgers to my kokanee box this year and these lures FAR outproduced any other dodger that I had in my box and it was clearly a notable difference. Some days we would fish 1 UV sling blade and 1 classic sling blade and ONLY get fish on the UV setup, I have become quite impressed with UV presentations this season and have been adding quite a bit of them to my tackle inventory.
