I do appreciate the point. I have my SM students doff and don a cylinder, and do some swimming in between, to make that very point. It works very well with AL80s, as Tom noted, above. But, when I have them wearing HP120s, even HP100s, it is just a wee bit more challenging.A sidemount diver is trained to be weighted properly so he can donate a bottle, without a problem of buoyancy.
Please note: Following is under consideration of non-wreck, cave or (extreme) technical diving.
Being someone always trying to optimize my equipment in terms of light travelling (and clutter free diving), I would like to challenge the ‘real’ need to have a long hose configuration for the right tank instead of using a short hose setup (with break-away bolt-snaps connected to necklace) for both tanks (referring to Steve Martin’s short-hose configuration for solo diving; see screenshots).
Before you shoot why this might be ‘craziest idea ever’, please consider following for OOA situations:
- Generally, OOA is only acceptable due to technical failure (in fact, OOA caused by lack of air monitoring is completely unacceptable (->terrible diver) and I would never dive with such divers)
- Air sharing is possible with short hose configuration (although having an impact on comfort due to distance)
- Air sharing results into team ascend anyway, hence, impact on comfort is limited to TTS.
- OOA being such a rare occasion, does above discomfort (due to distance during ascent) really matter? I doubt!
Please do not argue “what is the point?” – some divers are in favor of light travelling / minimal configuration, while others don’t mind bringing tons of equipment (and some of them looking like a ‘Christmas Tree’ ).
Curious about your opinions and a healthy discussion.
Cheers,
Dan
Yes, these are all neutral tanks.I have practice with AL-80 and 12L & 7L carbons without buoyancy problems, normally with Dry-suit
Yes, and as we noted, AL80s are not an issue. I don't use carbons, so I can't comment.I have practice with AL-80 and 12L & 7L carbons without buoyancy problems,
No, not at all what I said. And, I don't think that's what Tom said.If one reads your comments one can assume then that you guys are unable to dive without AL-80 for cave and wreck penetration, where you may need to un-clip one or more bottles.
Yes.We agree that it is not necessary to donate your tank, at the moment of a OOA or regulator problem it is time to ascent anyway and aboard the dive with a long or short hose.
Really good point!!What you propose is quite common here for people who have not been indoctrinated in the way of DIR etc.
