Clip this device onto your bcd so it's handy when you need to get your diving buddy's attention. A magnet is located inside on either end of the shaker with a ball bearing in between. Shaking the device moves the ball bearing, creating a loud Echo sound underwater. It's a great communication system...

Ample bag with shoulder strap and handle for arranging and protecting your regulator and accessories. It features a small additional case for stowing dive computers.
