Airlock Strike Inicators
Quit sacrificing your tapered leaders to the "bobber gods." The Air-Lock Strike Indicator is ultra buoyant, super visible, durable, easy to adjust, and won't render the butt section of your leader a kinky mess.
Air-lock strike indicators accommodate leader and tippet material of widely varying diameters. Use them on everything from 25 pound butt section material to 6x tippet. Thanks to the o-ring in the cap design, even thin diameter tippets don't slide through once the cap is locked down. Adjusting the position of the indicator on your leader is as easy as twisting the cap a half turn, sliding the indicator, and locking it back down. Once the indicator is removed, the leader emerges unscathed.
Air Lock strike indicators are manufactured by a little company called Field Systems Research based in Portland, Oregon. The two owners met on the banks of the Deschutes River in 1993, and have been fishing buddies ever since. Shortly after the acquaintance was made, they began grumbling to each other about how frustrating strike indicators were. More specifically-how poorly they attach to a leader. The objective was clear...find a better way to attach an indicator to the leader.
Frank built the first prototype out of a toothpaste tube and it's cap. It worked! The tube could be casted great distances without slippage! Even better, there was no damage to the leader and it was easy to adjust. Immediately, John began tuning the design, fashioning working prototypes, and testing the "you-know-what" out of them. The end result: an indicator that stays in place, is easy to adjust, won't kink or damage your leader.
