Product Information
This set pairs the Apeks XTX50 Dive Regulator with a matching Apeks XTX50 Octopus and an Apeks 2-Gauge Console, so your primary, backup, and instrumentation come from the same over-balanced, diaphragm design. The XTX50 first stage carries two HP ports and four MP ports on a rotating turret angled for clean hose routing, with an environmental dry system that keeps water out of the main spring chamber and helps prevent ice buildup in cold conditions. Both the primary second stage and the Octopus are pneumatically balanced for smooth, easy breathing, and each uses a large, easy-to-operate purge button with a 2-stage progressive purge for finer control when clearing.
Braided flexi-hoses run to both the primary and the Octopus, built lighter and more flexible while still holding up in cold water, and both regulators are compatible with EAN40 straight out of the box. The XTX50 comes with both the small and large Diver Changeable Exhaust tees included, so you can switch between a low-bubble setup for photography and a more compact, comfortable fit. If you ever need to move from a right-handed to a left-handed hose configuration, an Apeks Authorized Service Technician can convert either the primary or the Octopus. The Octopus mouthpiece and housing are also treated with an additive that targets bacteria, viruses, mold, and other organisms, which is welcome peace of mind on shared or rental gear.
Keeping an eye on your gas and depth is the Apeks 2-Gauge Console in black and dark grey, with a nickel-plated brass case, an anti-splinter polycarbonate dial window, and phosphorescent dials that stay readable when the light gets low. It reads pressure and depth down to 70m/230ft with a resettable max depth indicator, and an over-pressure capsule adds a layer of protection to the module itself. At checkout, choose DIN or Yoke for the connection type that matches the way you dive.

What is the Apeks XTX50 dive regulator?
The XTX50 pairs an over-balanced, environmentally sealed diaphragm first stage (the DST) with a pneumatically balanced second stage for smooth, easy breathing. It has 2 high-pressure and 4 medium-pressure ports mounted on a rotating turret, comes in yoke or DIN, and includes both a small and large diver-changeable exhaust tee. It's rated for cold water use below 10°C/50°F and is nitrox compatible up to 40% O2 straight out of the box.
How much does the Apeks XTX50 regulator weigh?
Per Apeks' listed specs, the complete XTX50 regulator (first and second stage) weighs 1269g in the yoke configuration and 1139g in the DIN configuration. The fact sheet doesn't break out a second-stage-only weight.
What first stage does the Apeks XTX50 use (is it the DST)?
Yes, the XTX50 is built around Apeks' DST first stage, an over-balanced, environmentally sealed diaphragm design. As you descend, the over-balancing feature lets medium-pressure gas in the hose increase faster than ambient pressure, which is meant to improve performance at depth. It has 2 HP and 4 MP ports on a rotating turret for easier hose routing.
What is the Apeks XTX50 Octopus?
The XTX50 Octopus is Apeks' alternate air source regulator, with a pneumatically balanced second stage, a breathing effort control knob to desensitize it when it's not in use, and a large 2-stage progressive purge button. It uses a silicone exhaust valve, a braided flexi-hose rated for cold water, and a Comfo-bite mouthpiece, and it's EAN40 compatible out of the box. Its molded parts are also treated with an additive Apeks says protects against bacteria, fungi, viruses, and other pathogens.
What's the second stage on the Apeks XTX50 like?
The XTX50's second stage is pneumatically balanced for smooth, easy breathing, with a large purge button that has a 2-stage progressive purge (a side press for lower flow, a center press for full clearing). It also has a soft-touch venturi lever and an opening effort control knob. Apeks lists the regulator's overall work-of-breathing score as an average of 0.70 joules/liter.
