For quick, effortless line adjustments in the open sea.
Thoughtfully designed by Alexey and freediving instructors, our Professional Pulley System makes lowering and raising bottom weights a breeze.
Made of robust fiberglass, this sturdy, easy to use locking mechanism releases your line with a gentle pull and automatically locks it in place when you let go. No more endless adjusting and reattaching knots or struggling to hold the bottom weight when change depths or resting in the middle of pulling up the weights at the end of your session.
Once you have tried it, you will never want to go back to using a plain carabiner!
