Sadly not Phi. The Head has the wings which are wider and the scrubber, being radial is definately bigger.

We could widen the frame size to accommodate if there is enough people interested in them. Just a thought...

Tough call, Phi.

The PRISM's head is designed to bolt to the mounting plate and spacing with the scrubber is critical. You probably want to have a unit (or at least an original backplate) to make sure it fits without undue stress.

In addition, you need a bit of space to attach and (especially) detach the scrubber basket. Am not sure how easy that would be to accomplish with bars on the side (where the tanks mount).

A design like the D.E.S. box that opens all around the sides may be a better solution. Maybe your black prototype, too. Hard to see from the closed lid back view you posted.

Enrique Alverez made a steel enclosure for my old prism, it was better than anything out there ant the time, it did make everything accessable without a screw driver
here's his site:

Stefan,
When we take the head off of the original SMI plate we also take the rubber spacer, being that you are now mounting to SS as opposed to a flexible plastic you some times need to shim out the head itself. It may sound difficult,

but it really is not.

There are new pics in the gallery called cold cave dolphin. that is a great shot of a side mount bail out.

***caveseeker7*** · 5th December 2005, 01:51

Even my ex wasn't that cold and wet ...

Saw them in the gallery earlier, nice going Dan.
Bit nippy but I like the sidemounts, too.

I modified the shoulder straps on the lower harness to connect to the small side clip on the PRISM CL, then used Tobins lower CL atachment on the Tech Waist straps.
I am using the Stock Counter lung Y connector, I found Tobins held the lungs in too close to my head and I was getting rubbed raw on my neck.
What are you guys doing with your SPG's bringing them over your shoulders or under your arms ? JDZ can you show me how you have attached yours ?

Cheers
Chris

And after a weekend of playing around in and out of the water, this is how I ended up also.
Three adapters at the origional bolt points holding wing and Y connector
Backplate with no shoulder harness bolted onto adapters
2" counterlung attachment down onto waist band using Tobins attachment
1" counterlung attachment to fastex clip replacing lower end of harness shoulder strap
2" belt as per normal.

Nice and simple, comfortable, but still leaves me with no upper mounting points for slings

The under counter lung Drings are a good idea in theory, but in practice having both the counterlungs and the harness straps didn't seem to quite work for me. Anyone wants to try for themselves, give me a call.

edit: I ordered some 900mm HP hoses to run the spg's over my shoulders and down through the counterlungs - ala Inspo. Seems the simplest way.

Hi Mike,

Don't get caught up with no "upper mounting points.." If you can run a bungy across your back and clip each side to each of the c/lung large clip, see the orange cord threaded through the clip strap in http://www.rebreatherworld.com/gallery/img1317.html ,then this should support the necks of the stage/sidemounts effectively.

Using the full length shoulder strap fed through the c/lung, I can now use the brass ring to attach the bungy clips to...

If you are looking at carrying only one sling/cylinder, then yes an alternate needs to be sought!!

Cheers, JDZ
