hose length

TobyFish · October 22nd, 2009, 04:46 PM

Hi all,

My diving is at recreational depths and penetration is wreck only and nowhere that I have to wriggle through so I was conisdering a 5ft hose but couldn't see a major driver for it as opposed to a 7-footer. It occurs to me though that because the 5footer is not hooked under the can light, it can be deployed fully without any shuffling of the light cord.

Is that right? or has my 3d brain failed me?

My 3d brain does agree. But if you have a can light, a 7-footer will probably route cleaner anyway - just a guess as I've never seen anyone actually use a 5-footer...

I think 5 footers were promoted for single cylinder use, although I dive 7 footer on both twins and a single.

I feel that if you have a canister light then the 7 ft hose is just as easy to maintain if not easier than the 5ft hose. I like the way the 7ft hose is routed behind the wing under the canister light across you chest and around your neck which is just enough hose to make this happen. To me it feels nicely secure that way. I feel that if there is any chance that you might be doing any type of penetration then I would rather have the hose than not. However I believe you are right about deploying the 5ft hose.

I use a 5 foot hose on a single tank. It's ok, and easy to deploy, but I'll be getting a 7' hose soon...

Having donated a 1.5m hose "in anger" I can confirm... no light cable re-routing necessary.
Just be careful to bring your donating hand back past the hose on the correct side to release the full length. Failure to do this results in the hose length being short and usually forces one or both divers to break horizontal trim and go vertical. hth

Dunno what kind of penetration on wrecks you do,
could the 7ft hose be the better choice for this, size of the entrance should not be the only criteria I guess.
I mean, swimming along hallways, up and down staircases, you don't do that?
Not only narrow passages, once you experience vastly reduced viz it might make more sense to swim out in line,
even when in a spacious freightroom or such, following a line.

I'm with Hoffi on this one. If you're going in any overhead I'd take the 7ft. Single-file exit is so much easier with the extra hose length - and as Hoffi points out, you don't need to wriggle to need single-file.

If you are planning a side-by side exit a 5ft is OK and it does donate pretty well. I used to use a 5 ft for single tank reef diving - and have donated "in anger" to someone from a different buddy pair when they OOG'd too far from their buddy!

You will have to be careful with hose routing in side-by side mode too - with the receiver at your right shoulder the 5 ft hose is quite short when routed around the back of their neck (much like a standard octopus length in PADI mode).
