In the fish world, scent (or lack thereof) is even more critical. Salmon and catfish can detect amino acids in water at less than one part per million. While virtually every other species-bass, walleyes and panfish included- typically taste their food before choosing whether or not to swallow it. In all cases, hands inevitably come in contact with lures and baits; but if you think deer can smell you coming, try tying on a lure with paws drizzled with gas and oil, digits dotted with Deet, fingers festering with nicotine. That's a recipe for bad luck. But it's also why Rippin Lips releasedNo Trace- a potent new scent elimination spray capable of reversing fishing fortunes. Developed over a two-year testing phase, No Trace doesn't cover up odors, itdestroysandeliminatesthem. The results are immediate-you'll notice an instant lack of any scent whatsoever. Smoke, gas, bug spray, sunscreen-it not only knocks out all odor molecules that repel fish, you can even spray it on a pair of old gym shoes and notice an immediate lack of odor. It's also totally safe for our fisheries. Any No Trace that enters the water has absolutely zero impact-it's sort of the other meaning behind the name.
