Comments about Oceanic EOS FDX10 DVT Regulator with Swivel:

Due to the swivel (which doesn't work well at all) you may only use Oceanic replacements - no braided hoses.
DVT module in the 1st stage produces a massive screeching noise after servicing. I have been told "you need to let the spring wear in". I have done at least 30 dives with this reg and the problem still occurs. I have also been told that the spring needs to be lubricated to stop the screeching, suggesting that qualified oceanic servicing people don't know what they're doing.

This reg delivers everything that the manufacturer says it does and more... The FDX10 1st Stage w/DVT paired with the EOS 2nd Stage is so balanced that you will think you are breathing on the surface even though you are at 100 feet... The dive/pre-dive switch is large and easy to adjust AND it works as designed... You just make sure that you set it to pre-dive before you hit the water and once you're under, roll it to dive and you're done... The breathing effort is controlled by the easily gripped knob and once you have it set to your preference, just leave it there, no need to fiddle with it, unless you want to... As for free flow issues, well, I had to make mine free flow by turning it mouthpiece UP on the surface... I just had to move the venturi switch to pre-dive and the free flow stopped immediately... The DVT feature on the FDX10 helps to keep the "cooties" out and the internal surfaces clean and safe from contamination... Thanks to Oceanic for making a fine, completely adjustable regulator that will serve me in my profession for a good, long time..!

The EOS is the best breathing regulator I have ever owned, and I have been diving for about 40 years. Additionally, you can't beat Oceanic's reputation for quality and service.

On my second open water dive the regulator went into free flow when I was demonstrating how to recover your second stage. I tapped it in my palm, and it wouldn't stop. I handed it to my instructor who was right there with me and went to my alternate secondary. He tried moving all of the adjustments and he could not make it stop either. We were at 20 feet, when we surfaced the tank was empty. Regulator was sent back to Dive shop then Oceanic factory. The factory has been very vague, first said they would ship me a different new one, then when I looked at it and compared serial numbers I pointed out to dive shop that it was same regulator. Upon further inquiry with factory we found paper work saying parts had been replaced. I hope that information is true and the regulator is safe to use by me or whoever winds up with it.

this reg is great once you're breathing off it, but there's one big flaw: the hose is only 30" long. its just long enough to use comfortably. it makes for a slightly more streamlined package, but that causes other problems: it's really too short to share with a buddy - that means you shouldn't use it with a combo octo/inflater. that eliminates the streamlining advantage right there. also when you switch from a snorkel to your reg its harder to find (even with a sweep). replacing the hose isn't a option either - the hose and swivel are one unit that has a non-standard male fitting going into the 2nd stage. it you plan to never use a combo octo - it's a 5, otherwise don't bother
