Rated 5 out of 5

Outstanding - Highly Recommend

I purchased an Ocea 1st/2nd stage set. As a photographer, I found the small exhaust T of the XL4+ 2nd stage allowed significant bubbles which blocked my view at key photographic moments. I also did not feel the XL4 2nd stage provided the ease of flow I am accustomed to from my other reg sets. After consulting with an Apeks tech I purchased the XTX50 to replace my XL4 primary 2nd stage. It is fantastic! The breathability is now what I would expect and the exhaust T is large enough to keep my field of view clear. There was also -no- noticeable weight difference in my mount, even after 2 hour dives. Highly recommend!

Pneumatically-balanced second stage results in smooth, easy breathing. The Apeks XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used. Press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc., then press in the center for the full effect of the purge, i.e., when regulator clearing etc. The large venturi lever has a soft touch rubber grip, which makes it easier to locate and use. The lever reduces the amount of grit ingress and therefore resists any possible friction giving a smooth operation. Easy-to-grip opening effort control knob keeps the diver in control. The 2nd stage is manufactured with active protection against infection as all molded parts are produced with an additive that kills MRSA, protects against E-Coli, bacteria and fungi, and is also very effective against viruses, mold, yeast and algae. A silicone exhaust valve improves the breathing performance of the regulator. The Comfo-Bite mouthpiece virtually eliminates jaw-fatigue. A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.

Features an innovative Diver Changeable Exhaust system (DCE). This system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. The regulator will be supplied with both sets of exhaust tees. Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must only be performed by an Apeks Authorized Service Technician. Suitable for cold water use. Compatible with EAN40 out of the box.
