Using A Long Hose Isn't Just For Tech Divers

Who said anything about FOLDING hoses?????

No need to worry about it..."Its an advanced techique"

The use of a 7' hose is not taught to new divers in standard OW classes anywhere.

Now I could just say "Take THE class" but I'm not like that. I would prefer if you could just search the old threads for rock bottom rather them having me teach the whole concept to you right now.

You offered to reveiw the math so c'mon lets reveiw. If you aren't prepared to back up your staterments then we'll leave it at that.

OK, OK - if you are going to bust my chops, I'll post some math for you (no charge)

Neither is the 5 foot, or the bungeed backup. Does that make it right?

part of the hipocracy on boards like these comes from the mods. they let fly anything that comes from the IN CLICK, while not thinking about the safety of new divers. new divers have more to think about and are under more stress. so the KEEP IT SIMPLE theory goes out the window because some elitist crumpacker tells the masses what they want to hear , and anyone with the slightest clue that comes to help is turned on and trashed by the click of the day.

Hmmm ... so far Nova, you have been by FAR the most abusive poster in this thread ... and so far the mods have let you get away with it.

So what, exactly, is it you're trying to tell us?

I love it when the people who need to take a class tell everyone else to. and then tell someone that CAN do a gas management plan that they will teach them .ROFL

Here it is, real quick and easy.

Assume a nice big SAC of 1 for each diver. 100 feet, so you have an ascent of about 3 minutes with an average depth of a little less than 3 atmospheres. So, say 8.5 cf for the direct ascent. Add 4.5 cf/person for the safety stop (1.5 atmospheres times about 3 minutes) and you have 13 cf/person. In a steel 95, 13/95*2640 ~ 350 psi/person, or 700 psi.

That was easy wasn't it?

Yea....So....maybe thats why this thread exists in the first place

So to answer, Maybe it (OW classes) should...as long as it doesn't include the advanced technique of folding.

Do you know why the long hose is donated instead of the back up reg? I didn't think you did. the long hose is donated 1 because it works 2 ( this is the part that most of you should remember) it is because of a thing called roll off. if your left post rolls off in an overhead enviroment, the ooa diver will now be hit twice with ooa. instead the donating diver hits a reg that has been rolled off he/she can reach back and turn the left post on. left post roll off , right post roll on.

As you can see, the length of the hose doesn't mean it works.

history and training. just not here

there you go assuming again....
careful, it'll get 'cha one day. Might not make that 27 more you were talking about. If you look into my profile you'll find that I was trained by mostly the same organizations as you.
First off, I was replying to a poster who was talking about a rec rig. A single tank, no overhead, no roll-off.
Second, you do not donate the long hoes because it is on the right post, you donate it to facilitate exiting an overhead where single file swimming is required during an OOA situation. You do, or should connect it to the right post for the reasons you mentioned (I'll give you that much). Two different things. Further more, the diver may be diving singles with one 1st stage or dual 1st's and a Y or H valve. No one mentioned doubles as the whole conversation has been revolving around rec divers using the long hose.
Quit reaching for straws...
