DGX Custom - Apeks DS4 or DST/XTX50 Sidemount Reg Package

The Apeks DS4/XTX50 Sidemount Regulator Package contains everything you need for an ultra performance regulator setup in a sidemount style configuration. Some divers prefer a shorter {60 in | 1.5 m} hose in their configuration, but some divers still prefer the {84 in | 2.1 m} hose, and our package gives you the choice. Hose materials are your choice of rubber or braided flex for the low-pressure hoses and rubber, braided flex or braided stainless-steel for the high-pressure hoses. We also offer an upgrade from the DS4 fixed first stages to the DST swivel first stages. This package is also available in Right/Left configuration utilizing the ambidextrous feature of the XTX50 second stage. This DGX Custom package is assembled and integrated by Dive Gear Express using Apeks first and second stage regulators together with our premium quality hoses, gauges, adapters, stainless steel hardware and other accessories, including:

• Two Apeks DS4 First Stages (optionally upgrade to DST swivel first stages)
• Two Apeks XTX50 Second Stages
• One DGX { 60 in | 152 cm } or { 84 in | 213 cm } LP Reg Hose
• One DGX { 22 in | 56 cm } LP Reg Hose
• Two DGX Swivel Adapters for the Second Stages
• Two DGX SPGs (Choice of Size, Face Color, PSI or BAR)
• Two DGX { 6 in | 15 cm } or { 9 in | 23 cm } HP hoses for the SPGs
• Necklace, S/S Bolt Snap, two DIN Caps, two Bungee Loops for SPGs
• Optional Inflation hoses for BC and Drysuit ({ 22 in | 56 cm } is typical)

The Apeks DS4 First Stage is a work horse with years of proven performance and reliability preferred by the most demanding technical divers. The Apeks DS4 is a unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the intermediate pressure gas in the hose to increase at a rate faster than ambient resulting in superb performance at extreme depths. The polished chrome plated body has one standard high pressure 7/16-inch hose port and four standard high-flow low pressure 3/8-inch hose ports in fixed orientation; popular for sidemount configurations. An environmental seal keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out. The DS4 comes standard with a DIN connector and is Nitrox Ready.

The Apeks XTX50 second stage is a pneumatically-balanced design that results in smooth, easy breathing. The all black soft silicone front cover has a large and easy to operate purge button that features two-step progressive operation. Press the purge on the side for a lower flow rate (useful where more control is required such as filling lift bags) then press in the center for the full effect of the purge such as when clearing water. An easy-to-grip knob allows the diver to fine tune the cracking pressure (aka opening effort.) It also offers a large venturi (Dive /Pre-Dive) lever for better gas flow and to reduce free flow upon initial entry. A heat exchanger which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water. The popular Apeks Comfo-bite™ mouthpiece by Aqualung greatly reduces jaw fatigue.
