Apeks ATX40 DS4 Regulator Set
The ATX40 DS4 regulator represents excellent value for money as both the ATX40 and DS4 second stage have earned their stripes. Both ATX40 and DS4 regulators can be seen at dive sites all around the UK, due to their reliability, robustness and not to mention their superb ease of breathing. The ATX40 second stage is lightweight and compact, balanced, and features a diver adjustable venturi feature. Matched with the dry sealed and balanced DS4 first stage this package is the ultimate workhorse regulator. The Apeks ATX40 DS4 regulator can be used effectively on singles, twinsets, and stage bottles, keeping all your regulators the same helps if you need to change out regs at the last moment.
