H valve set up for redundancy

[phsdive]

I put this set up together for dives where I wanted some redundancy; for testing out newly built reg's, deeper reef dives and deep wreck dives where I wanted a bail out on bottom gas (I carry a 5 litre deco gas bottle with a 40% mix - so it's good above 90 or so feet.) Of course the H valve doesn't help with an OOA situation.

The valve is a normal Dive Right din valve with a H valve addition. It allows me to add a second reg with all the bit and pieces, pressure gauge etc. I put it together with the VDH backplate and found that the H valve needed to be turned around as the 1st stage of the Scubapro Mk 2 was hitting the backplate. I don't like it turned around and will look for something with a small 1st stage. Wouldn't mind an old USD reg - if you can think of a suitable model with small first stage please post.

I'm going to put a Zeagle 18 lb wing on the plate, but will wait until I see the VDH version.



The turned around 1st stage is not a good set up for wrecks.

- That's a neat solution. I've seen those modular valve parts and was wondering if something like that could be done.

Likewise, an interesting solution. Some thoughts come to mind though:

1. Would it be possible to rotate the H valve so that the single-hose is pointing up and the knob points up? It might present less of a snag profile in a wreck as you pointed out earlier. It doesn't need to be perfectly vertical as I imagine the tank will get in the way. so just some degree of rotation would suffice.

2. Of course for wreck, a twin tank system might be better - one post can have the DH, and the other post can use the single-hoser

I've done the H-Valve thing too and have also done a Dive Rite 200Bar/300Bar manifold too. The site will not allow me to post pics as I'm an AOL user so if I can send pics to someone and they want to post them on my behalf they are worth it. I have double hose regs and set ups for both recreational and technical diving.

The site does not let ANYONE post pictures directly no matter what browser they are using. Everyone uses a photo hosting site like Photobucket, Image Shack, Square Space etc.....

At the top of every category on the website there is this link on How To Post Pictures
