Long hose question

Not from me, the 2 times I have been in the situation of an OOA buddy despite being shown where the AAS was, they both ripped the reg from my mouth [not at the same time obviously ] it was then I realised that it was best to assume that would happen and configure my kit accordingly, it was no fun trying to find an occy' with someone that close.

Safe diving,

I've been OOA once and my buddy was on a standard hose, I took the AAS and it all went quite relaxed and as we were both trained to do by PADI.

I now dive with Endoman who has adopted the long hose (7' I think) and having done it for real with a standard hose and been relaxed I can see that being relaxed but having a bit more hose would be a benefit.

Not sure how things would go if I was scared shitless and panicing though, it'd be interesting to see if there is a reason to be concerned.

Generally some good info on there but the first page does have a real screamer on it.

Pop quiz, folks - what's wrong with this diagram? It's supposed to depict two divers (one of which has gone OOG) swimming out of a wreck through a confined space.



No one who is either cave-trained or DIR is allowed to answer!

Also, why does he have his backup routed *under* his arm if he's using a long hose?! How's he supposed to get that in his gob?!

The second diver's head has become detached.

What do l win?

Donating diver should take up position No2 ?

Broady is correct, the out of gas diver should be at the front.

Ah, but they may be back kicking out of a confined space?.

Just to put something else into the mixing pot...

I use a long primary hose on my set up. My main cylinder is a 15l, and I side sling a 3l pony.

My reasoning behind this is that in another diver diver being in an OOA situation, I can donate (or have my primary taken!), whilst I am in control of my secondary and redundant air source. The long hose excess is loosely bungeed to the side of my 15l, and my secondary hose and reg bungeed to my side slung.

It also gives me the option to hand over my secondary air source, if I feel it is required. I am in control of this.

It's the end of the dive, if having to make decisions like this IMO anyway.

For open water diving a 1.5m hose is fine and to some extent solves the issue. If you are doing any exercises with BSAC (you said dive club) primary donation cannot be taught (though it is not banned) and so this can make things difficult across the team.

Personally I would try both the 1.5m and the 2m with a friend and get them to "panic" a little. See how you get on. The 1.5 is stowed under the arm so it is very like a standard octo if you want it to be.

The idea of primary donation and long hose diving is that the OOG diver asks for the reg (just like the proper BSAC training) and is given it (unlike the new DTP) This implies a lack of panic.

The issue is when another diver appears from nowhere and grabs the reg in your mouth. This, I'm told, can happen when in a big group of inexperienced divers. Not a situation I am in often TBH. Long hose use is Hogarthian and not just DIR. DIR protocols would suggest the other diver not panicking. BSAC encourage long hose octopus and frown on primary donation so you need a kind of work around. The usual one is breathe the backup reg and use the primary as octo. This is fine unless you have a diver grab the reg from your mouth. They are going to get nowhere with a short hose

The upshot therefore is you need to adapt your rig slightly to accommodate the team you are in. A good pre-dive brief and buddy check also helps a lot of course.

That's why we are going to do some drills next time we dive.
