Product Description


Apeks DS4 XTX50 Regulator, a great, British Reg

apeks_xtx50_a-clampThe Apeks DS4 XTX50 regulator is the bench mark in terms of reliability and durability and will often be seen on dive boats arond the country. The DS4 first stage is the twinset set regulator of choice but provides excellent hose routing on single cylinders and stage bottles for divers who do not require a swivelling turret. The DS4 first stage is compact but delivers large volumes of gas when you need it most.

As an member of the XTX family the XTX50 second stage builds on the reputation of the ATX range. Improvements include diver changeable exhaust tee's, reversible venturi control, diver adjustable breathing resistance and the ability to change the second stage from right to left handed to suit a range of hose configurations.

The XTX50 DS4 regulator is perfect for twinsets as the ports are in the perfect location for neat and efficient hose routing whilst the breathing resistance knob and venturi contol allow an XTX50 to be used as a backup without worrying about free flows.

Diagrams explaining the technical detail of the XTX50's cracking resistant control can be found here.

Great Product, sold by an equally great company. Review by Tom
To begin with, I had been looking around for some regulators for a while as i have been diving with second hand hand me downs that my dive club provided. so it was time for me to get a set of my own. I set out to find a cheap set of cold water rated regs and after much deliberation landed on Apeks.....

I then searched far and wide to find the best deal that I could find and trust. This is when i found Aquanauts.
The price is second to none, and i would be extremely impressed if someone found these regs cheaper elsewhere.
The delivery was quick and used a reputable company that work professionally and with excellent communication, explaining exactly when the product will arrive (even trackable online... which i made a game of as it updates after each order)

Aquanauts themselves have a brilliant range and will be getting my custom again in the future. I was more than happy with their communications and with the price and quality of the product.

after ordering spoke to my dive leader and found that our club will be joining the Aquanauts team for a dive in plymouth next month too.
:) brilliant company
:) brilliant product
:) happy customer.
