Value of 4th Cell & Computer

mverick

Not afraid of the Kit. It's not needed. My gear works I don't have repeated problems with it. That's why the HSExplorer is a paper weight. Repeated problems.



If you have a scrubber break through at 210feet what do you do? Your DIL bottle ain't enought to bring you up. Pull a hose off at depth? Mushroom valve ain't sealing? Lot of little stuff to go wrong with a Rebreather.

I carry bailout. Never needed it. But, it's always there. Not afraid of the Kit either. Just don't want uneeded things.

Heck, why don't we just put in 10 O2 cells with voting logic?

To be honest. If doing it manually, I only want 2 cells. A flush tells me the bad one. Why do I need three? For a computer and to not do the flush, you need 3. But I still do the flush. My butt, I'll flush.

I fail to see how having a VR3 straped to my right wrist and vision handset on the left, makes my rig comberson. I think you will be have much more shite banging around you than me, with all your OC tins .

The wire wrapped around your right arm that I don't have.

The extra bottles on your back that are hard to get to.

All have a greater entanglement hazard in a wreck.

If there clipable on my waist, they are in easy reach.

I don't want extra stuff on my back I can't get to. My buddy in a tight wreck can't always see my back when slipping through a hole. And, my unit isn't as large so I can get in tighter spaces. Pull my bailout bottles, shove them through and I go next. You can't do that if they are bolted to your back making your rig larger.

All the wrecks I dive through aren't EASY swim throughs. And lots of them have fishing lines all over them. I don't want extra snags. Which would be extra wires.

One thing, I do like the case on the Insp/Prism/Vision. I wish a meg had one. Keeps snags down too..

Exactly what is the use of the VR3 with O2 sensor? If you don't trust your Hud/Vision/2 controllers. Why are you diving that unit?

Spot the incongruity? (I may have just made that word up)

No kit is needed until it's needed.

I carry bailout too - it's a second Rebreather and it weighs a damn ton. It has 2 cells and is manual so that fits with your philosophy I think.

The original question was from a Classic user. One of the failure modes is ZERO PO2 monitoring, even if 2 cells are fine. In this instance you wouldn't have the option - I appreciate you have a different unit. Hence my recommendation regarding 4th cells. TBH, I don't think there is much overhead involved in a cable and 4th cell VR£ - and it does do your deco too!

My friend takes the view that breakthrough is almost impossible to get on a Classic if you do your job right and don't push the scrubber. Hose coming loose? Total loop flood - that is the only failure mode that you can't get back from. I think a cut hose is the more likely scenario if you've followed the setup drills. The fittings are bullet-proof... Mushroom valve? SCR or do the hose-grip drill. Lots of stuff to go wrong as you say - but an almost equal number of ways to fix the situation.

I dont think 3ltrs of 02 and DIL make me any more snagable than say your meg as last time i looked at one they had the cylinders uncased, as for making the rig wider oh yeah, all of a few inches.



The bottles on the case are very easy to get at to turn on and off, and to pull the whips out is even easyer (if you can reach your hip d-ring you can reach the valves




Personley i find diving my unit like this much more streamlined and enables me to squeeze in places more so than with a few 80's banging away under my arms




Looks pretty streamlined to me m8 and yes i do trust my electronics, never had a problem with controler 1 or 2, or the HUD and handset for that matter. But by linking the VR3 to a 4th cell it gives me 1 more get out of jail card as a redundant PO2 monitor.

And if i lost the handset display due to broken cable for example (like Nigelh) both controlers will still be holding SP as they are independant to the display, but at least i can still physicaly see the no.s and not have to blindly trust the HUD's lights that SP is still being maintained. Pretty nice feature to have IMHO when i still have a few hours of deco to do and still be able to see PO2 and not just a green lights

As i said i have never needed it yet, but it is a nice feature to have to complement my vision elecs, i see it of being more use to me than some big tins clanging around under my arms.

Truth be told,

At great depths the small BOB's are a much better option. And with all you've added. Probably cheaper.

Few inches means I can't squeeze through some holes. Like I said, the bailout tanks are easy to un clip, squeeze through the hole, and clip back. So, you're a few inches wider? Few inches could easily keep me out of a hole.

For the extra tanks, I thought you also carried a Drysuit inflation bottle? Which also widened the rig.

And, I said I liked the case on the inspiration/prism/vision. But by putting your tanks mounted outside your rig. You just killed that. And, if you sling the tanks they are easier to get to in case of entaglement.

P.S you are right about the extra few inches, well thats what my wife keeps telling me. They make all the difference

I have a hose of my air bailout. Run my suit inflation off it.

Not a big believer in argon. At least, no effect for me. Others think it's like having a furnace in your suit.

Have you ever thought of a twinspiration for the deep long dives? I would think with all the Inspiration cages available that would be a better/ safer option. Twin loops.

Never got married. Couldn't keep the other women in the world from knowing what a horse d..k was... LOL... Magnum XL's all the way. Still tight. Nickname in High School was Magnum. Then they come out with the condoms. Who'd of thought. Designer must have been a girl I dated...

What is the width of your unit? And Height?

I've posted my megs on here before but can't find it. JR's Inspiration with cage was a little slimmer. I've modified mine now, but still think his is slimmer. I'll measure mine and post it. One of the reasons people went with mounting the Argon bottle under the unit. Although, I'm not a fan of that.

Rebreather, that is.

And I'm serious about I wouldn't want any wider then mine. There are holes I'd like to get into now that 2 inches would let me through. Never poked a hole in a drysuit yet. But, it's a Gates VSN1100 and it's pretty bullet proof. Have had a boot come off during a dive. Or, open up at the taped seal. Now there stitched on.

Like they say, you ain't wrecking if you don't come up with rust all over your suit.
