Bass are strongly sight oriented when feeding. Berkley Power baits and other amino acids or real-prey based flavorings undoubtedly tend to make bass hold onto soft lures longer, once they taste them. Very slowly moved or stationary lures may be picked-up and tasted by bass, IF the lures smell edible after bass approach to very short range. Bass' sight-feeding tactics don't usually involve following scent trails.
Water rapidly disperses scents and almost everything underwater has a scent.
Your lure may smell like a live crawfish, but all the crawfish in the safety of their holes also smell like crawfish. The passing schools of sunfish and shad, which the bass ignore unless the prey blunder into striking range, also have their own smells. If you waste more time and casts applying a scent than the scent increases your odds of getting a hit, you end up with a net loss. If you must frequently reapply a scent product, you probably aren't making a catch gain. All rights reserved.
