This regulator bag fro Apeks is large enough to fit an entire set of regulators including first stage, primary second stage, octopus, instrument console and hoses.
The XTX 40 DS4 is composed of the XTX 40 second stage and DS4 first stage. The DS4 first stage regulator uses a dry sealed system and an over balanced diaphragm design where the intermediate pressure supplied to the second stage increases as the diver descends to greater depths which results in superior breathing performance regardless of depth.
The XTX40 octopus can be converted from a right handed hose configuration (as supplied from the APEKS factory in the standard) to a left handed one.
Modular flexibility - The MaxDepth gauge is still one of the most dependable instruments around for divers who are just starting out or don't feel they need the advanced features of a Personal Dive Computer just yet. But don't worry, Oceanic's modular gauge design allows you to easily swap out the depth gauge module with an Oceanic PDC as your needs change and your experience grows.
