Thoughtfully designed by Alexey and freediving instructors, our Professional Pulley System makes lowering and raising bottom weights a breeze.
The pulley is made of sturdy fiberglass and an easy to use locking mechanism. This will release 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 you change depths. During your dive session or at the end when have to pull up the bottom weight.
Once you have tried it, you will never want to go back to using a plain carabiner!
Works with lines from 8 to 12 mm diameters. See an example of our older plastic version in action below.
