DIR Regulator Configuration

[Starfish]

I have shared the "regular" short hose configuration with my husband during practice out-of-air and when he sucked down a tank so fast on a dive that he shared mine for a few extra minutes as we may a leisurly ascent before our safety stop.  In both cases you have to be, as you know, right next to the person.<br><br>He was certified years ago by NAUI and I recently with PADI.<br>Even though PADI didn't require the "old fashion" sharing of one regulator, we have also practiced the passing back and forth of regs in a simulated OOA.<br><br>We have also had the challenge of keeping back up regs in the triangle.<br><br>The final challenge was free flow reg, at depth, which because of his body position at the time, he didn't see and I had to reach out and correct (turns out he heard it and was saying to himself, "hmm what is that?" when I grabbed it).<br><br>Now we're talking about a possible change to long hose.<br><br>Anyone take Rescue classes with a long hose configuration?<br>
