The DS4 first stage lacks the rotating turret found on the XTX50 first stage and offers one HP port. This compact first stage is a time-proven workhorse that has been embraced by the technical community around the world.

The XTX 200 is second only to the Black Sapphire and quite rightly enjoys its position towards the top of the Apeks regulator range. The definitive blend of style and high performance, every detail on this product has been carefully designed to offer a regulator of the highest quality.

The XTX40 Octopus provides the same features and performance as the XTX40 second stage and includes left /right-hand reversibility. It comes with a high-visibility yellow front cover and a 36” yellow hose. It is suitable for cold water use (below 10 C / 50 F).
