"Secondary" display for Vision units

We are talking about 2 separate and different things:

You are talking about having the controller issue while diving, bailing out and going back with a known malfunction controller with 1 additional cell.
I am talking about removing the batteries from the malfunction controller to disable it, then diving the unit for the rest of the trip as mCCR.

Also, your scenario about dealing with the Vision problem doesn't work from personal experience of others who have PM'ed me. Just FYI...

I know exactly what you are talking about, its not how i would dive my unit. It either all works when i go in, or if it dont i fix it or dont dive it. Last time i looked the Vision was being sold as a ECCR and not a MCCR

As for my scenarios ref the vision, if the elecs dont work like this during fault modes. I suggest you take it up with MP and AP as this is how they state the elecs work. Just FYI

Gareth,

IMHO, you are looking to argue about your configuration instead of participating within the realm of this thread.

While I respect your choice of configuration and your willingness to sit out the remaining of a dive trip instead of diving the unit as mCCR, I am trying to achieve something else altogether.

With that said, may I respectfully ask you to refrain from arguing your point on this thread unless you have something useful to contribute to the discussion ?

I have no interest of arguing with you, but you might find this part of a PM interesting...

The BIG problem with the vision is no backup. whatever the posters say if a fault is flagged or controller 1/2 crapps out or you loose the handset, the ability to to monitor po2 is lost as the HUD will be too busy displaying warnings to show you po2. This effectivly in my opinion means the vision has no po2 backup. I have had this happen to me twice.

Yes, it might not be applicable to you as you have a 4th cell and VR-3 display plumbed in, but is applicable for standard Vision units with single display.

The HUD has no way of monitoring PO2 or giving warnings, it only gives out the info provided by the controlers. If the controlers flag faults etc they will display them via the handset and HUD. So inturn if the HUD is displaying warnings you still have a controler/s working. So in other words if you have no handset but a HUD you must have at least 1 controler working or 2 .

I dont like the thought of just seeing green lights, and no visual PO2 info incase of handset failure. Hence why i fitted the 4th cell. At least i can see a number to verify the controlers are still doing there job and also the HUD as a guide. If they are not doing there job, agian i can still see a number so i just run it manualy to finsh the deco/dive off.

I know this is not the info you wanted, so i will but out

Not trying to offend, but you were not contributing directly to what I am after.

Your first post was asking why I wanted to see all 3 cells on the secondary display. Then proceed to explain why your own configuration is better (that I have read many times before) and making patronizing comments about "fix it or don't dive it" and "Vision is ECCR, not mCCR"...

Again, the realm of the thread is I am trying to create an independent secondary display for my Vision so I could:

effectively isolate the Vision controller by restricting O2 flow to the solenoid (i.e. in-line flow stop) if I feel the controller is failing during the dive. Then bail-out of the dive in mCCR mode using the secondary display.
If I was on a dive trip where I can't get the Vision fixed before the next dive, I will remove the Vision batteries and continue the rest of the trip diving the unit as mCCR unit (i.e. by plugging the O2 first stage as well) using the secondary display.

Does anyone know if APD gets upset if the lid is sent back with the 4th-cell adapter still connected ?

If not, then an y-cable could be one of the easiest way for remoavble before sending back to APD - not that a switchbox is difficult either.

Someone (Lord M I think) posted a week or so ago that he'd taken his head back to APD for a check over. They'd commented positively on the design and modularity of the Narked@90 holder he had fitted.

So, I'd say, probably not.....

Cheers,

I searched and read that post. Cheers for the heads-up...

Please note this discussion is specific to Vision electronic before commenting:

Has anyone here done an independent secondary display for the Vision yet that uses all 3 cells ?

I am not talking about plumbing a VR-3 to a 4th cell, but an independent digital display (i.e. Sartek, Subsea, COPIS) connecting PARALLEL to the existing 3 cells.

A while back, Jason M mentioned that he will look into it, but I don't think based on his delivery rate that he will be able to do so anytime soon...

That leaves only Sartek since the COPIS battery holder is too big to fit inside the Vision lid.

Or a Shearwater HUD...
