Blind Exits on a Rebreather

... however, IMHO, the bag solution should work better when you don't have perfectly flat surfaces on the PO2 display. For example, the new KISS PO2 meters have curve display to magnify the numbers. HH has the same.

I guess you could always have a matching curved face on the perspex -could even have a couple of elastic loops to help keep it on the display

True.

I am just thinking about situation when someone has more than 1 unit (for example, a KISS and a Insp-HH) than would have to make a different tube for each unit where as the bag is universal.

Also, once you have a tube with curve surface, you can't use it on both the curved PO2 display and on (say) a SPG...

4th cell VR£ might help. Backlit and you could get that close to your mask. If this is likely to happen a lot, you could fill the small indent of the screen with an acrylic resin ("still water" or "acrylic water"). A bit excessive, but maybe more robust than bags of water if needed.

I think the original question was more to do with the ascent based on not being able to see. I guess you have the SCR option or bailing out. Or trust your handsets to work... (Caveat: Newbie!)

I read something recently about a blind CCR diver, he'd apparently had his unit modified by AP to give him a series of different audible warnings to let him know the performance of the unit, perhaps this is an option that could be made available to more people?

Either that, or PPO2 displays working little pins on a braille system.

Actually it would be an excellent solution if it could be turn on/off at will.

That way, when diving the system in OW or non-silty locations, you could turn it off to save the massive headache from the constant noise. But when in a silt-out situation, turn it on.

The only problem with that is not getting used to recognizing the signal (i.e. different beeping means different things) until needed...

I'd oftened wondered what the attraction of diving if blind was as it is such a visual-based sport, but to be fair blind is a sliding scale and a lot of people have some vision. Sorry, tangent, ahem...

Yes, as Phi says it is a CK and has no solenoid so that option is out. Hammerhead... er, no ta... VR£, not likely, I was reluctant to spend £30 on the 12yr old Aladin I bought recently. Actually, the other diver I mentioned in my original post who had the total light failure did in fact find his way out by using the backlight on his VR£. I was impressed, it's a lot of money just for a back-up torch though I chose the KISS because it was minimal so I don't really want to go complicating it. Squeaky noises...? Noooo... I have a slice of perspex rod somewhere that I used for reading my OC gauges so that may be the answer. On the old CK (like mine), the display faceplate is flat so it would work.

Coming off the loop in blind conditions isn't something I fancy as one of the reasons I bought the Rebreather was the massive gas endurance in such situations as opposed to OC. I suppose, thinking about it, you would just manage it as a handset failure.

I think these days we can do a little better than that! You can get quite cheap voice synthesiser chips now. I fancy Joanna Lumley please... Imagine her dulcet tones as you bid the world farewell...

"PO2 2.55. Goodbye..."







(This last bit only really works if a) You are British and know who Joanna Lumley is and b) You have had the misfortune to sign up to email on AOL...)

I think Anne Robinson would be more appropriate: "You are the weakest link, goodbye".

Or maybe a certain Rebreather World moderator with a kindly "Ha... twat...".

EBT

Only if I get paid royalties...

Theres blind flying techniques, but I have my doubts about their effectiveness when you're wobbling in depth. Can't you just SCR until out of the mud?
