VENTURI-ASSISTED PRIMARY PORT
The DX4 Balanced Diaphragm First Stage isn't simply reliable, it
also has a unique feature called Venturi-Assist which actually helps
provide a "turbo boost" of air flow to the second stage as depth or demand increases. Simply put, the DX4 provides more air to the
second stage when you need it most.
SEALED DESIGN
The advanced design of the DX4 Balanced Diaphragm First Stage isolates the critical
seats and o-rings from the harsh environment. This helps prevent internal corrosion
and contaminant buildup, leading to more consistent performance between service
intervals.
ENVIRONMENTAL PROTECTION
For cold water or high sediment diving you can also depend on an optional 'dry' Environmental
Protection Kit for the DX4 Diaphragm to help prevent freeze-ups and contamination
that effect other first stages. The environmental kit completely seals the
upper spring chamber of the first stage to prevent ice crystallization without the hassle
and mess of silicone or alcohol based fluids.
2 HIGH PRESSURE PORTS
2 High pressure ports allow for convenient positioning of the first stage in either the up or down position. High pressure attachments can be mounted on either side or
accommodate redundant systems.
4 LOW PRESSURE PORTS
4 Low pressure ports allow for convenient routing of all low pressure hoses.
DIN OR USA YOKE
The DX4 First Stage is available standard with your choice of either a 330 BAR DIN or
USA Yoke fitting. A convertible yoke is also available that can convert a DIN fitting to
a USA Yoke without the use of tools.
NITROX COMPATIBILITY
Factory cleaned and assembled in a clean room environment with special o-rings,
halocarbon based lubricants and color-coded for easy identification, the DX4 NITROX
gives you all you need in a reliable Nitrox-ready regulator.
DELTA 4
Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4 is one hot new regulator ready to take on all challengers with improved performance, new features, improved styling.
2005 ScubaLab Tester's Choice
"Hooked up to the breathing simulator, the Delta 4 delivered Very Good to Excellent performance in all the RMV/depth categories, earning the highest simulator scores of all the regs in it's price group. In ocean tests, the reg was also a champion, collecting the highest total ergo score in its price group. In particular, divers liked the swivel and the mouthpiece, and felt both the adjustment knob and dive/pre-dive switch were easy to use, even when wearing gloves."
