Long hose question

Just a word on the official line, but HQ told me that primary donation should not be taught to inexperienced divers. I think people undergoing Ocean and Sports Diver training fall under this category, whereas Dive Leaders are 'experienced'. Qualified Sports Divers I think it depends on the individual.

We had a good chat about primary donation on my BSAC trimix instructor course, and with the BSAC Instructor Trainers we had a good debate about primary donatrion (one Instructor Trainer very much for, one Instructor Trainer very much anti.)

Going back to the Original Post. There are two separate issues - the long hose and primary donation.

I used to have a 2m hose and it was great. When I needed to put someone on it (a trainee was running low and panicking) I was able to maintain a firm grip, eye contact, and make it to the surface in a controlled way. The extra hose did not hinder this at all.

7ft is useful if you are ever going to need to be in single file. Do you ever go inside a wreck (even just a little bit?).

Ok , this probably will sound dumb, but do you really want a panicked ooa diver leading you out of a wreck/cave??

Not qualified just curious, or is it better to be able to keep an eye on him, so he can't sneak up and mess with from behind (cue the dude)

There are loads of variables you can add in to this but the upshot is if they are infront of you they wont swim off without the air source, but can get through confined spaces without you both jamming the opening

As somebody who has wasted money on this, a 2m hose is a fraction too short, it should be a 2.1m (7 foot) hose. The extra 10cm does make a difference if you are hog wrapping, it lets you turn your head fully to the left.

Ah, I see, thanks for info Marty.

won't this depend somewhat on your circumference? There are some who a seven foot hose would be enormous on, and others that even that may be too short.

The whole problem with the question is that it assumes you have neglected RULE ONE.

Rule one is 'Don't dive with Strokes'.

From then on the assumption is built in that your buddy is to be trusted.

Using a long hose with novice is using it as a fashion accessory. It is the wrong equipment at the wrong time in the wrong place. I have a nice 12L single on a BCD with a pony for diving with newbies. They watch me and copy me. Monkey see, monkey do. Diving my wonderful rebreather would be totally unfair and unhelpful. Ditto a long hose.

Panic should only be a short lived thing....when the gas source is re-established the panic should subside....then when it has then you are in a position to move off. In a team of three, the third team member who is not donating or receiving, leads out, followed by the OOG diver, followed by the donor who is in touch contact with the OOG diver.

In monitoing the gas usage you may decide to transfer the OOG diver onto No 1s long hose and re-order as appropriate ... but the "weakened" diver is always in the middle or in front.

Even if it doesn't the last thing you want is someone who isn't happy with nothing to breathe behind you where you can't see them.
