Oceanic Delta 4 with longhose?

[superkingkong]

Hi guys,

I've got the Delta 4 from ST few months back. Now, I would like to use it with a 7' hose. and since delta 4 comes with a swivel, i guess it needs to be removed.

so, if i get a 7' hose from ST, can i just replace it myself?

btw, i don't have any specia tools but a wrench. and i've only took out hose from 1st stage before ... not 2nd stage.

thanks.

Why would you want to dive with a 7' hose?

why remove the swivel?

is that against DIR rules?

After some research, first reason, i found out that standard hose are not able to fit the swivel, hence oceanic is selling a longhose with swiwel attached. So, if i'm going to use the standard hose, i need to remove the swivel, and replaced with a inlet coupling from a GT3/Alpha 8.

second reason, additional point of failure.

i like tbe idea of DIR, in an OOA situation, i donate my primary and i'll use my secondary bungeed to a necklace.

i do kind of like that idea of the 7 foot hose, though I probably won't be doing it anytime soon....i'd be kind of annoyed though if I had to ditch the swivel (i have the same reg). why not get the oceanic long hose?

1st, if u have a longhose... it's kinda flexible already.
2nd, it's identified as an additional point of failure. well, not too much for me now, but if i'm to go towards tech later, i don't want to but another longhose.
3rd, it costs twice as much as the original 7' hose that is without a swiwel

Interesting how the idea of a 7' hose brought up DIR. I just want to point out that a 7' hose does not equal DIR, nor does it make you DIR compliant. DIR is as much a philosophy as it is a gear choice.

On to the swivel. The theory about the swivel is it introduces a possible failure point, and they have failed in the past. There has been recalls on them, but as far as I know (AFAIK) it's never happened to Oceanic.

The ultimate goal is to reduce the chances of failure to insure a safe dive, thus a diver would get rid of anything that is not necessary to a dive and thus maximise the safety aspect.

In other words, the more complex something is, the more likely it is to fail.

i do agree with u... DIR is all about philosophy.

but in sports diving, there is nothing about longhose, but just a reg and an octo.

so, i would say, longhose is related to DIR/tech line, not because they want you to or it's a must in DIR, but the understanding of safety. One does not follow blindly, but when questioned, one must know why they need this and that., hence, the answer shouldn't be .. because DIR says so...

I have a Sherwood Maximus Reg and it has a swivel on it. I just switched to a 7ft. hose with no problems. I actually like the swivel there. I think that it sucks that the oceanic will not fit a normal hose and you have to buy one of theirs. I understand what people say about the swivel being just another failure point, but to me that is the way that it came from the factory so I will keep it until I see a problem with it. It is not just some accesory that I added.

My primary is on a 40 " hose with a swivel.

With a 7ft hose, I see no need for a swivel and would not bother with it. Put it away for future use. It may come in handy again.

I have played with a number of regulators and switched out a lot of hoses. Have not met one yet that needed a "special" tool. Mind you however, I have no experience with Oceanic regs.

On the note of DIR and the 7 ft hose. A 7 ft hose is DIR, but simply using a 7 ft hose does not necessarily mean the rig is DIR compliant. And DIR has more to do with training than just equipment configuration.

BTW, at recreational depths in open water diving one can still be DIR compliant without the 7 ft hose.
