Apeks XTX50 / DS4

Apeks XTX50/DS4 - Twinset Regulator Set

The Apeks XTX50 / DS4 set is an excellent choice for technical and recreational divers seeking a feature-rich, high-quality regulator at an affordable price. Equipped with the advanced DS4 first stage and the XTX50 second stage, this setup ensures smooth, effortless breathing at any depth—even in cold water. The Apeks XTX50 / DS4 offers durability, comfort, and reliability, making it perfect for divers who prioritize performance and safety.

First Stage DS4

The DS4 first stage features a unique over-balanced diaphragm design, which allows the intermediate gas pressure in the hose to increase at a rate faster than ambient temperature as the diver descends. This provides exceptional performance at depth. Additionally, the dry-sealed system keeps water out of the main spring chamber, preventing ice build-up and keeping contaminants out, making this regulator suitable for extreme conditions. The DS4 includes one HP port and four MP ports, offering versatile configuration options. The DIN connection ensures durability and reliability for various diving setups.

Second Stage XTX50

The pneumatically balanced XTX50 second stage delivers smooth and easy breathing even at great depths. It’s equipped with large, user-friendly purge buttons that can be easily operated, even with thick gloves. The purge button offers 2-stage progressive purging: pressing from the side provides a softer purge, ideal for precise tasks like filling lift bags, while a full center press delivers maximum purge power.

This second stage also features a large Venturi lever with a soft-touch rubber grip, which reduces sand ingress and friction, ensuring smooth operation. The easy-to-grip opening effort control knob allows divers to manage breathing resistance effectively. Additionally, the XTX50 is designed with active anti-bacterial technology, providing protection against bacteria, fungi, and viruses.

With the Comfo-bite™ mouthpiece, jaw fatigue is minimized, making long dives more comfortable. An integrated heat exchanger surrounds the valve mechanism, dispersing the cooling effect of gas expansion while absorbing warmth from the surrounding water.

• 2x XTX50 second stages (color choice: black or yellow)
