It is your job do a buddy check and inform your buddy where they are to find their oct on you. So their should be no worry and you will most likely see them coming.
I was thinking that you may be showing someone with limited expirence a way of doing it that runs afowl of training and in some cases very reciently.
I can see it now:
LongHose: If you need to share air this (holding up the primary) is what I will give you.
NewDiver: What is that arround your neck?
LongHose: That is _MY_ backup.
NewDiver: (Eyes glaze over, head spins, wonders if LongHose has been smoking some of the local plantlife)
I had some "spirited" conversations about why have two divers swapping regs instead of one diver. I get it, I was just wondering how it was in the "real world". I would not want to cause someone undue stress because I was going against their training. I realize that a OOA diver may take the one out of your mouth anyhow but none the less I expected more turmoil reguarding this.
We get regular comments and interest and, on one occasion, a little sarcasm / agression from a DM
That is my biggest fear. I do not want to debate the merits of it which I may not be able to do effectively. Someone *could* argue that my setup is confusing and adds risk. My only defence is that you will always find the reg in my mouth.
We don't dive with random buddies or do solo dives. Not worth it. The team is properly assembled or the dive does not happen.
Dont get me wrong I see the value in that but I am sure I will be doing a lot of random buddy diving this due to the fact I will be vacationing with non-divers so I have no choice except not dive.
I like the merits of the long hose setup but do not want to debate its use. I do know that it is not a DIR only thing. The reason I posted here was for 2 reasons one, plenty of long hose users and two I will skip the messages of why I should not be doing that. My appologies for not keeping it strictly DIR. One other question I have is do you run into that many long hoses while diving.. I am not talking about Florida now
I am thinking tropical destinations where the ratio of 2-3 dives per year people go.
And I am ONLY refering to Rec dives
Thanks for all the good info
