**Tuning Tips** Challenger teaser heads on your 3-Fly-Rigs may need tuning at times to dial in just the right movement preferred from your teaser. When tuning teaser head, bend plastic very slowly over your thumb, bending over the total tail area of the teaser. Warming the teaser will help the tuning process and will help save the finish. Challenger heads are factory tuned and can be ran right out of the package, extra tuning is for the experienced angler looking to satisfy the perfect movement.
