Oceanic Delta 4.1
The FDX-10 first stage of the Oceanic Delta 4.1 comes with an environmental kit and Dry Valve Technology (DVT), which seals off the high-pressure inlet at the yoke to keep out moisture and contaminants.
The second stage is fitted with another Oceanic invention: Dynamic Adjustment. Once set by the diver, it automatically maintains breathing resistance throughout the dive.
This reg smoked the breathing machine in the test RMV/depth category for recreational diving, and it did nearly as well at the deeper test stops.
It also earned Very Good ratings in all ergo test categories, and the breathing-resistance knob was among the best in this go-round.
- Weight 2 lb., 10 oz.
- 1st Stage Overbalanced diaphragm
- Ports 2HP, 4LP
- 2nd Stage Mechanically balanced
- Adjustments Dive/Predive switch, breathing-resistance knob
A great reg with some nice features. We can’t complain about the performance or the price.
