Steel Chassis for PRISM

Chris · 1st December 2005, 00:51

Thanks Mike
I have actually ditched the Backplate off mine and now running a Zeagle TechPac Waist Harness bolted to Tobins SS backplate atachment, with a Zeagle 44lbs Bladder. 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.

The Tech has some really nice Small Dring mounting points all the way down its back that I think will work well for side mounting, I will be mucking about with this on the weekend.

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.

It worked fine when using a hood or Drysuit but I am just diving in a pair of shorts now so comfort is high on the list.

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

Anything is possible, Assuming you want 7 ltr to incorporate bailout. If not and you still have to sling a bottle not sure why you would dive that way. I like a sidemount sling for stage/bail out tanks. They lie away from your front and CL. In my personal experience I always find it necessary to try a couple of different ways and choose a style that makes sense to me. With that said, I have never reinvented the wheel and always end up diving a known and proven way, but always spend a bunch of time and money experimenting.

What ever you end up doing Armadillo makes a nice little setup to sling bail out. I dive with OC and CCR divers who incorporate it into there kits. I love it and adapted to it immediately, sorry I was not shown this style when I first started diving doubles

I'm looking for a set up which will provide the following:
- provide enough gas for deeper dives to obviate the need for bail outs larger than say 7ltrs
- utilise a method of attached 3 or 4 cylinders to the unit solidly
- Be a start point for a double or highly redundant unit
- Protect the head and scrubber
- allow accessories to munted to it such as torches etc in a streamlined manner
- add weight - I wear enough lead to allow 6-9lbs to be rmoved easily
- not screw up the grat balance the rig has now

I intend to be doing some deeper dives and woudl ideally like to run 2 x 7ltr and 2 x 3 ltr cylinders on the rig as back mounted gas.
1 x 7ltr EANX Bailout
1 x 7ltr Trimix diluent and bail out
1 x 3ltr Air for suit and wing inflation
1 x 3ltr Oxygen

Hi Chris,

I've got my setup really comfy at the moment.... rather than explain it all now, I will take some photos tonight and do a little writeup and hopefully post tonight/tomorrow...

Just to start,.... I have put my plate shoulder straps through each of the clung flaps and clip onto the "shoulder" risers of the plate. The bottom of the clungs still clip onto the risers from the front of the waistbelt....

till later...

Cheers, JDZ

Simon, my current rig does this easily.... the 3lt air can be addressed differently...JDZ

Work in progress soon but..................

Using the standard upper harness and counterlungs, mated to the lower harness of a transpac with Tobins plate for mounting.
need a crotchy and will be changing the standrd straps on the transpc for 1" to meet the counterlungs on the corners, standard 2" with tobin waistband connectors.

D rings will be connected to the old upper mount points on the Transpac with a length of 2" webbing coming over the shoulder and connecting to a dring hanging around nipple height.

this hould provdie the comfort of the standrd harness with the utility of the transpac and easy stage attachements.

I've attached some photos in the Prism gallery, http://www.rebreatherworld.com/galle...e.php?i=1310&c=, somehow they were posted in the reverse order to the way that I wanted them in, however the photos show the points I want to get across.

If you haven't seen the prism harness/clungs up close, you may get lost in the photos..

I'll dress up the rest of the gear, including the sidemounts, in a few days and post more later, need a dummy/buddy... and I'm out of town for a couple of days...

Cheers, JDZ

John, just looked at the pictures, looks good. Clean and streamlined.

Hi Martin
Have you got any pics of how you have slung your bottles ?
I am still playing "Make The Harness" at the moment using the PRISM Counterlungs as the shoulders of the harness, thinking of stitching a Dring to around the middle of the CL.

Tried doing it with a harness under the CL and using a side D from Cool Hardware but it just felt yuck and I found I was getting a tops bruise on my shoulder from the DRing.

Cheers
Chris

Not at the moment but give me a week or two and I will post them. Keep in mind I do not use the stock set up from SMI I use a dave weber system. If you go to ADM you can see the attachments they sell for back plates. I would not sling a bailout bottle off of my CL, but that is just me. I did not buy mine I made my own, but if you do not want to there system is perfect to buy

Chris · 1st December 2005, 20:47

Thanks Martin
I don't know many using the stock PRISM/Gimp Harness.
I don't know why SMI even provide it with the unit; almost all of us down here have stripped it off for Backplates or other options for better comfort and streamlining.

Maybe SMI should go the way of Jetsam and ICS in having the Harness as an option.

Cheers
Chris

Hi Chris,

There is no doubt that the Prism harness as supplied is a very comfortable for its designed, upto 40m bimble dive....

It, however, is not designed for tekdiving... and hence the reasons for all these mods...

It would make sense to have the harness/bc as an option, but I suppose SMI does want to sell a complete unit!!

Cheers, JDZ
