Azimuth & VR3

Hello,
I am planning to purchase an Azimuth and would like to connect my VR3 on it. I read about P-Ports but I am not sure if the Azimuth includes one on its counter-lung in standard.

What parts do I need ?
Where can I buy the connection kit ?

In advance thank you.

Best Regards,

Nicolas

The Azimuth does not come with a P-Connector when sold new. Most of the used ones already have it installed.
Installation requires purchase of a P-Connector, suggest purchase from W+S in Germany. Reliable worldwide and fair prices.

Installation requires a small pair of scissors, some aquaseal, and 5 minutes. Very well detailed here on one of my old pages:

The plug-in interface for that is available from Delta-P along with the VR-3. Funny, the interface part looks strangely like something I would design...

Re: Azimuth & VR3

I had a P port installed on my Azimuth. In fact Dave was kind enough to do the installation for me. It appeared to be a very simple process. I just closed my eyes as he cut into my inhalation bag and it was over in just a few seconds, About 24 hours later, just enough time to let the Aquaseal set, I was ready to dive. Works great and is a much better design than what I was first sent. Thanks again Dave.

And you ought to mention what a *piece of shit* was sent to you as the "factory" part to add the cell, and what you did about it... :)

Dave's right, The first factory part sent with my HS Explorer was designed to attach to the overpressure valve on the inhalation bag. This cell holder was shaped like a cone approx. 2.75 to 3 inches in length, that fit a R22 sensor and screwed into the overpressure valve as a replacement to the valve. When attached to the bag the cone and cable were forced against the hard shell of the rebreather causing it to be twisted. The cell holder was never a good fit to the valve to begin with. Popping off at times if any pressure was placed against the side of the cone. This was especially a problem when performing a positive pressure check with the system. The cone would be forced against the back of the rebreather and detached on two separate attempts. Needless to say I refused to take the unit in the water fearing it would flood during a dive. Dave was nice enough to install a P-connector and manufactured a a new cell holder of his design which not only provided a secure fit, but also a very low profile to the surface of the bag even when inflated.

?? Is there an OPV on the inhale bag?

My Azi has the OPV on the exhale side connected to the loop via a lenght of hose?

EDIT: Aha, OK the pics from Tecme shows the new OPV design. Nicer looking, but having it on the inhale side is not ideal for SCR.

Re: Azimuth & VR3

Hello,
On the exhalation bag there is a draining port. The is no "adaptor" existing to fix an oxygen cell ? It would avoid to multiply the holes.
Cheers,
Nicolas

That will be tricky if you want the cell to sit inside the bag.

You could always put the cell on a "T" in the inhale hose, but I would not do it.

The best is perhaps to buy (or get inspired by) one of these rather nice looking things: O2 House Azimth

If you use the Extendair scrubber there is room to modify it bit to have cells on the inhale side of it.

Re: Azimuth & VR3

The "factory" piece of shit 02 cell holder was for the drain plug, not the exhaust valve, and was so poorly made that it actually would pop off the rig under normal pressure test. It was not threaded correctly and was misdimensioned. A *really* sorry piece of "life support equipment". Just shameful. It would have caused an instant loop flood. Bad stuff. Maker ought to be ashamed of it. Provided with the Explorer as the "factory" solution. Caveat Emptor.

Nothing that an hour on the lathe to make a new probe and 5 minutes at the picnic table at the dive shop installing a P-Connector didn't cure though. Re-used the cable and all is well.

Mr. Becker: Be almost time to see you again! Boat goes into the water in 3 weeks.
