For decades, serious river fishermen have been secretly tinkering with and modifying Panther Martin&';s original Classic Regulars. Over time, these secret modifications developed into the colors and components found in the new Custom Salmon & Steelhead series here. Now Panther Martin is making these fishing secrets public with custom pre-loaded lures ready to fish! The black nickel hooks are extra strong and less visible. The black nickel swivel at the front eliminates line twist, but more importantly, it reduces the leverage that a big rolling fish can use to dislodge the hook. Oversized patented Panther MartinA(R) Convex/Concave blades slow the spin, lower the vibration frequency, and increase the sonic thump and wobble. Genuine silver-plated blades are critical to fishermen for the authentic bait-fish like light they reflect. Holographic Black works well in dark water and dark lighting conditions. Each lure comes with Black Nickel MUSTADA(R) Big Gun open eye Siwash Hook.
