Product description Seac 2nd Stage Octo-Synchro
Both the second stage and dedicated octo bodies are made from technopolymer and elastomer plastics. The second stage features a locking diaphragm system and a dive/pre-dive control lever.
The demand valve is an asymmetric design, and Seac claims that this allows maximum valve opening to improve performance at depth.
There is a large elastomer front cover to allow simple manual purging, and the cover-plates are locked in place with Seac’s membrane block system. There is also a large surface exhaust valve and an ergonomic exhaust port with a built-in chin-rest.
The octo has a yellow front cover for instant identification, and both second stages are fitted with rubber low-pressure hoses and ergonomic mouthpieces.
