Was to indicate that long hoses are not needed in the recreational situation if we are sticking to shallow penetration and recreational limit diving... hearing you that 40m wouldnt do if you had an OOG...
Hmmmm. Yes and no (don't you love shades of gray!).
Not wanting to get too sidetracked on the long hose issue, but it's not the length of the penetration that is the issue but the types of passages you go down. Too many people don't have the situational awareness needed to realise that the hatchway they are about to swim through is too small for two divers to pass at the same time. THere are plenty of places for divers to get in to trouble on shallow wrecks doing short penetrations.
If (and I am biased here of course) a wreck course is taught properly, then a student will start to think about sizes of passageways - even though the PADI wreck course explicitly limits divers from passing through them.
To a certain extent, a pony can compensate for the (lack of) long hose - it gives you the ability to indepently exit through restrictions and then share air normally once pas the restriction. But it does also encourage a "I'm alright jack" attitude. It's real easy for an OOG diver using a pony to just swim out of the wreck without looking back for their buddy. It;s important to remember that the buddy is your gas source that's going to get out up to the surface once you are out, so you need to stick together.
The very reason I posted this rather than PM it is I believe there are a bunch of reccy's out there that need to learn where such equipment is useful in the recreational arena and know when they are approaching or are indeed in that zone - if they are not reccy divers, then they will already know. - I think Binky said it well in another thread where he said something to the tune of being prepared for the dive you are about to undertake.
I think all divers need to think about whether they are prepared for the dive, and need to think about whether they have the skills/equipment/attitude to do the dive safely. I've seen some shocking "technical" divers who couldn't actually plan a 20m reef dive, let alone the dives they are actually doing. Scary stuff.
Even in "recreational limits" there's a lot of things that can go wrong.
