DGX Custom - Poseidon Xstream Sidemount Reg Package
The Poseidon Xstream Sidemount Regulator Package contains everything you need for an ultra high performance regulator setup in a sidemount style configuration using ambidextrous second stages. 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. The package, using the Poseidon Xstream Black first stages along with the Xstream Black second stage regulators, comes to you tested and assembled by Dive Gear Express and includes:
- Two Poseidon Xstream Black First Stages
- Two Xstream Black Second Stages
- LP Hose Choice of Rubber or Braided Flex
- One { 60 in | 152 cm } or { 84 in | 213 cm } LP Reg Hose
- One { 22 in | 56 cm } LP Reg Hose
- Two Swivel Adapters for the Second Stages
- Two SPGs (Choice of Size, Face Color, PSI or BAR)
- HP Hose Choice of Rubber, Braided Flex, or Braided Stainless-Steel
- Two { 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
- Cold Water and Nitrox Ready
The Xstream first stage uses a unique synthetic ruby sphere that virtually eliminates high pressure seat wear that is common in knife edge design seating systems. The Xstream first stage also uses a rolling diaphragm design that eliminates any restriction in movement, which creates a smooth transfer of gas from the first stage to the second stage. This rolling diaphragm design further creates a insulating barrier so there is no need for an additional environmental kit. The Xstream has five low pressure standard 3/8-inch UNF ports and two high pressure standard 7/16-inch UNF ports. The Xstream Black version is Nitrox Ready, incorporating oxygen compatible o-rings and lubricant. The Xstream is CE certified to EN250 European cold water standards.
The low-profile compact Xstream second stage uses pilot-operated upstream demand valve technology that also seals the seat without the use of conventional knife edge design seating systems. This servo-assist feature allows for very low inhalation effort and also eliminates any need for a venturi switch or adjustment knob. The second stage is also ambidextrous, allowing both left and right hose routing and breathes equally well in nearly any swimming position while the side mounted exhaust directs the bubbles out of the field of vision.

Rigging the SPG on Stage and Sidemount Bottles
The classic method technical divers use to rig a stage or sidemount bottle is a compact or "brass & glass" gauge assembled with a very short high-pressure hose folded back on itself against the first stage and permanently tied in place with a piece of cave line. We do NOT recommend doing this with a rubber or flex hose because the hose is also permanently stressed at the two weakest points, the fitting swages. Although not as convenient to read, allow the SPG and hose assembly to lie straight against the tank while held against the side of the cylinder under a hose retainer. Because the short hose is less able to absorb the impact of rapid pressurization, we recommend following best practice to depress and hold the second stage purge while slowly opening the cylinder valve until the regulator begins equalizing with the cylinder pressure.
If you prefer folding the hose, then use a bungee loop (about 1 foot of 3/16" with the ends tied together in a fisherman's knot or we prefer an overhand loop w/pigtail) instead of cave line because when the regulator is off the stage the bungee loop allows the hose to be unfolded. Some divers also prefer using a slightly longer hose when folding, hopefully offering a reduction in stress on the folded hose. Regardless, in our experience all short rubber or flex hoses still may fail prematurely from being folded back on themselves. Recent availability of short high-pressure hoses with a braided stainless steel jacket, together with the bungee loop rigging method, seems to be the most durable and reliable compromise.
Here is one final thought... ask yourself "Do I really need a full size SPG?" Sometimes the exact amount of the gas remaining in an off-board bottle is not being used to control the dive. The only reason for the presence of the SPG on the travel or bailout bottle is the diver just needs an indication of cylinder contents as full, partial, or empty. If your diving application doesn't need an exact reading on gas remaining in the cylinder, an inexpensive button SPG will significantly reduce the number of failure points. This is especially true of bailout bottle applications, whereupon switch to bailout also terminates the dive and knowing the exact tank pressure is unlikely to be meaningful.
