DIR/GUE - No steel stage bottles

[dumpsterDiver]

Just remember...the system is a whole approach to diving. Just taking bits and pieces you like generally invalidates the reasons behind a lot of the choices.

I've got no DIR training, but I've followed a number of DIR "bits and pieces" and I've been happy with their application. Blindly following a system that you don't understand might not be advisable, but many of the general prinicipals are applicable and useful to my diving.

How do you manage the 7 foot hose if the reg is not in your mouth? Is it clipped off? In some reg holder? Something else?? Is it quicker or at least as quick to deply than the one in your mouth?

I think this is a good example of picking and choosing without fully understanding the system.

The hose length is less important than the fact that you donate the reg you are breathing. You know right where it is and you know it is working. When your buddy wants air he wants it right then. You, OTH, have a few moments to address any potential problem with your secondary.

I would highly question the need/wisdom for a 7' octo in an OW rig.

I've been using a 7 foot hose on my OW rig for about 10 years now with no issues or problems, even without a can light. It works fine as long as you keep it stowed neatly. I've used it exactly twice, to share air with two different people who thought they were OOA, but were actually not. On the second occasion in particular, the extra length came in extremely handy, and I was very glad to have it available.

Between two properly trained divers with good buoyancy, a long hose makes air shares easier, especially while swimming. Between those with poor control, it can just give you more room to accelerate before the reg is pulled from the OOA Diver's mouth.

That's not exactly a problem with the hose. The solution there is not "don't use a 7 foot hose for OW diving" - it's "train the divers so that they have better control". And besides, the OOA diver should be physically holding on to the donated long hose and/or second stage anyway, to avoid exactly the problem you describe.

Yes, steels can theoretically be handled with weight adjustment but real world experience beats out never-ever theory every single time.

What do you mean by weight adjustment? Thanks.

What do you mean by weight adjustment? Thanks.

In his post

they tried to compensate by filling the tank boot of their steels with that spray foam stuff used to fill cracks in houses.

I read that but it obviously went over my head as I did not think that was "weight adjustment" but just some dork diver tom foolery. thanks.

It's also from the OP.

I know that they are neg. bouyant, but this can be handed with weight adjustment as needed.

I'm actually kind of curious as to whether which agency teaches you to tuck your primary reg through your bungeed backup?

You mis-read the post to which you directed this response.

Understand. But from my POV much of the DIR is based on doing cave diving. I'm purely open water, so I adapt what makes sense for me.

... I choose to put my long hose on my octo. In an emergency, I don't want to have to take my primary out of my mouth. That's just one more step that could go wrong. If the distressed diver pulls it out of my mouth, I'll deal with it and just go to my octo. But I don't see a reason that I need to add another step in a crisis. Hopefully if I'm doing my job as a buddy, I'll see it coming and be ready to shove the octo into his/her mouth as I'm approached.

... I believe that an open ocean diver can learn a lot from DIR, but it takes a filter. If I were diving in overhead, I'd look at it differently.

I don't want to discuss "long-hose for backup" since there's no valid argument for this praxis but these few sentences clearly show:
a) that you didn't get anything about DIR, don't be offended but you don't have a clue
b) how bad it can be when you pick few bits that you like out well-thought system and apply it to something else
