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, and the new FDX-10 First Stage featuring DVT (Dry Valve Technology).
Most downstream demand valve regulators are calibrated during manufacturing to a single, 'middle of the road' operation. Whether finning up current at 100+ feet or merely snorkelling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the Delta 4's adjustment knob enables complete control...set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.
Ever wonder why they call it a "dust cap" and not a water cap? DVT eliminates the possibility of moisture entering the first stage with a simple, yet ingenious design. No hassle, no worries. What about performance? DVT doesn't impact first stage performance even at 198 feet with just 200 psi in your tank.
The result? An end to flooded regulators! Oceanic's exclusive DVT is designed to automatically eliminate moisture intrusion and contaminants from entering your breathing system.
Amazing. Simple. Patented. And by the way, only available on Oceanic Regulators.
