The XTX50/DS4 is the same as the XTX50 in terms of performance but uses a different first stage. The DS4 first stage lacks the rotating turret found on the XTX50 first stage and offers one HP port.
Sharing the same technical features with the higher end XTX200, the XTX100 first stage is machined from a solid piece of marine brass, but finished in luxurious satin chrome rather than the polished chrome or PVD of the more expensive models.
The XTX Tungsten is built on the XTX200 platform but with a truly unique, added feature: it is protected with a hard, durable Physical Vapor Deposition (PVD) finish. The coating is made of high quality grades of Titanium, Zirconium and Chromium.
The XTX 200 is second only to the XTX Tungsten 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 Flight Regulator from Apeks is the lightest regulator in the world! This revolutionary regulator has been made using advanced composite materials selected for their optimum strength to weight ratio and is extremely easy to use.
Apeks Nitrox regulators are suitable for use with up to 100% O2 and are colour-coded for easy identification.
Before the XTX range of regulators came along, the ATX models ruled the seas. The ATX40 is still available today and offers a fully balanced first and second stage with cold water capability (can be used in all temperatures including those below 10 C / 50 F).
The new MTX-R is based on the MTX, a regulator that was developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test.
