Seac Jack Computer

Seac Jack Computer

Seac’s Jack is a wristwatch-style dive-computer designed primarily for freedivers, but it can also be used for single-mix nitrox or air scuba.

It uses Taravana and Hemoptysis as well as a Buhlmann ZHL-16B algorithm to monitor each single dive run, and calculates minimum recovery times as well as the maximum safe depth that can be reached on a dive. The Jack has a stainless-steel case with a scratch-resistant Sapphire glass face, and is depth-rated to 220m. Expect to pay £339.
