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.

AirLock Strike Indicators come in 3 sizes- 3/4", 1', 1 1/4"

3 Per Package.

Very similar to thingamabobbers but have unique attachment system. The indicator attaches to your leader without any resulting kinks. Try them out, you'll be glad you did.
