ScubaLab puts eight new dive computers to the test and offers scuba gear reviews of each one tested.

These two models were tested but not included in the September/October issue of the magazine.

Constructed of a flexible polypropylene blade and a thermoplastic rubber foot pocket in an open-heel design, Tilos’s lightweight Torrent fins offer increased flexibility, which translates to a more comfortable kicking experience.

This rear-entry, 4 mm, high-density neoprene dry suit weighs 50 percent less than traditional neoprene dry suits. When ScubaLab tested dry suits this past winter, the immediate reaction from every tester was “Is this a dry suit?”

This serious dive tool uses a modular, interchangeable design so divers have a system that’s easy to use, no matter the environment. The knife offers a choice of a sharp drop-point or blunt-tip blade made from a hardened stainless steel alloy, making it durable and rust-resistant.

The Pro Light is an extremely light and well-balanced fin that’s surprisingly responsive and powerful. The compact blade features a soft rubber center panel that’s flanked by thermoplastic stiffeners and flexible yet supportive side rails. This combination provides nice blade flex when kicking, and allows you to maintain stability whether you prefer flutter, scissor or frog style kicking. The fin has two flaps along the end of the blade, a design that allows divers to change direction with only minimal kicking effort.

The Apeks XTX200, the company’s flagship regulator, gets high marks for its excellent breathing characteristics: well-designed user adjustments, great hose swivel connection on the second stage, and cool-looking chrome finish on the compact, environmentally sealed, over-balanced diaphragm first stage.
