Drager FFM with Golem BOV

Lancer4545 · 12th February 2008, 09:30

I have just received a shiny new Golen Vario BOV (Thanks Jakub) and fitted it to my Meg for use with my Drager FFM.

In the Drager Manual they state you cannot use 2 second stage regs with the FFM as one of the second stages will free flow. This is clearly what I have done by fitting the BOV when you bail out.

My question is, who has tried this set-up and what have you found and what advise do you have.

I am going to dive it on Thursday and am keen to see how it goes.

I'll put up a breif report on it after I get back if anyone is interested.

Regards,

Lance

Hey Marv,

Great news.......Looks like we both have a new toy to play with.

I have the Vario all hooked up and ready to go and looking forward to being able to bail out with one quick twist again

Will put up a post tomorrow on how it went.

Been using a the Panorama and one of Jakub's BOvs for a couple of months now and really, really confortable. The only thing I can whinge about is the downward hanging 2nd stage impinges on my chest when trying to look down at my instruments. Would have preffered he second stage to be on the front and the switch on the bottom as I am pretty sure the weisght would not be noticable in the water.

Otherwise and extremely easy to use set-up and the 2nd stage breaths like a dream.

That mask just refuses to fog up!

nope as you are using an internal mouthbite so you can breathe off the bov without effecting the side reg (just as your normal breathing from Rebreather doesnt effect side reg,)

If you get freeflow from the side reg in general (as you can in the side reg when descending etc) just fit a sliding shut off valve on side reg

Yes......I had thought of that after I had put the post up. The 2 second stage scenario would be for OC breathing through the nasal cup with both second stages sharing the same air space.

I dived it today and there were no nasty surprises and worked a treat. It's slightly heavier than the DSV and it is noticable with the loop weights fitted leaving it sitting well down and out of the way when you take the mask off whilst on OC bailout with the FFM clipped off onto your harness.

Other than that the only other thing I noticed was as previously stated, you can't move your head down quite as far as with the DSV but it's not a real issue..

One problem with the FFM which stared me in the face every time I rigged up was the bailout second stage reg sitting there with a P Port adapter. It worked fine for me if and when I had to bail out with the FFM but what if I had to take the mask off!! The other problem that troubled me was if my dive buddy needed to use my bail out and then there was the issue of not having standardised equipment in the group.......This takes care of that problem!!

The bottom line.......Well if you like to use a BOV and have a FFM then you're going to like it. You have the ability to add to the loop by breathing in through you nose and out into the loop through your mouth. Venting the loop is easy as and if youre like me and like to vent through your nose the FFM just sits there. Bailing out nose breathing isn't really an option with the dead air space within the mask so it's better not done.

I like it......money well spent.

Lance

I'm diving a Vision and have also purchased the FFM and Golem BOV. I am resigned at the moment to making a few mistakes with the way I am going to plumb the whole BOV and bailout thing as I can't make up my mind the best (KISS) way to go. I have put my hands on an omniswivel for the BOV 2nd stage, a QD with adapter to fit hose and female QD with a view to running a hose from by lean bailout to the dil manifold and from the dil manifold to the BOV with a free flow device. Am I way off?

Any help with routing of hoses would be appreciated. Photos better again.

Hi Tim,

I think you are on the right path.

I use a M&J QD plus a check valve on my offboard gas to supply dil to the manifold. From there I now run 2 hoses, one to the Apeks second stage and another to the BOV second stage. Both have a flow stop and I don't use a swivel. I found they are really not necessary if you have the hoses cut to the correct length.

Let me know if you'd like to see a pic of how I have it set up.

Regards,

Lance

Thanks Lance, nice to hear that I am getting there from someone in the know. The hose that you are running to the Apeks second stage I presume is for an out of air buddy? I will try it without the swivel and see how I get on...next issue for me is length of hoses...can you give me an idea of what you are using? A couple of pics of the routes you took for the hoses would be very helpful.

Thanks again

Timmy

Tim,

The Drager I am using comes with an Apeks second stage which is plugged into one of the secondary (side P'Ports) and is there to pressurize the mask and allow you to nose breathe if necessary. Then you have the BOV which is plugged into the Primary P'Port.

You will still need another second stage on your bailout gas in case you have to donate gas to anyone or bail out off the mask.

Regards,

Lance
