BOV Use Poll

There's a means of plumbing that eliminates the need for QC'ing during the stressful parts of a CO2 bailout. I refer the linked BOV plumbing

You can bail to offboard. If you're bailing to hypoxic gas, then I would have filled the onboard with a mix containing some 50% O2, and when reaching 20m or so, I would

1) simply open the onboard tank valve and BOV now connected to safe gas.
or
2) QC a safe gas to the offboard inlet

All offboards would have 2nd stages. IMV there should be no dependance on the BOV, thus making it extra gear and complication. However, the extra gear/complication is justified

If they were all this small and light, it might make a difference in my decision of to BOV or not

Does anyone have an approximate deliverly date for either the new APD or Golem BOV?

Sorry, complete hijack

Stephane, who is that band your linked to? I just listened to the samples, and I'm going to download the album from i-tunes

Hi Babar,

They are great, they are really great. I saw them last thursday night in concert, it was amazing! These guys rock, well no, they afrobeat !!!

They come from Canada, maybe you'll have a chance to see them.

Hijack off, sorry.

I'm going to go against the grain here. While I use a BOV on my Sport Kiss, I don't use one, or plan to use one on my Mk 15.5. Having the additional low pressure hose routed along one side, the drag from a larger BOV, plus the added failure-point, makes it not worthwhile for me. I know that people will say that if I'd had a serious CO2 hit that I'd think differently, however; I am constantly asking myself if my breathing rate is in proportion to my workload or if I am having any other symptoms of high CO2. I feel that if I am aware of these things, then I can deal with the situation before it is a problem. I also dive enough that I think I am fairly well in tune with my unit, so I tend to notice when somthing is beginning to feel "off".

Furthermore, on most units, you can essentially go OC by exhaling every breath from your nose. This will provide fresh breath nearly as quickly as turning a knob on a BOV without the need to do anything else. I tend to do this peroidically anyway if I am working hard to be sure that my CO2 levels are not rising.

I'll now duck for cover

Aloha,
Charlie

i would never dive with out a bov, i had done for many years,
but after home building, i spent the money on a nemotec bag o shit, that failed on the first dive, as we were testing a new po2 gauge that then failed!! when it goes wrong it goes wrong.
charlie although i had one fail through bad design to me it is still one of your best defences against CO2 and i have no doubt it would have saved my friend that thought the way you do about co2,
we designed a bov a few years back which i think we will produce in the future and i think the apd bov is a good step in the right direction for there unit.
kind regards john routley
