So here I am on a dive boat. . . . I'm geared up in my fancy schmancy dive gear. I've read post that because I have the equivalent of an Air 2 some have said they won't want to dive with someone who does. I don't have a back up SPG. Some have indicated that I must be an inferiorly trained diver because I also didn't pack my dive tables. And I'm diving split fins. Now I need an instabuddy.
I can tell you I will stay by your side. I won't intentionally wander off under water. After a few pleasantries and hand shake I will ask you what you wanted to do for the dive. Which direction are we going to head and what depth and for how long. What is going to be our turn around PSI and who should lead. I will also tell you my alternate is my Atomic and that you will breath off my primary in an OOA/low on air situation. Check you for your BC releases and ask about your air (but won't touch or check the valve). After the dives I would like to get a beer. Now, if you were a good dive buddy to me I'd buy you one too. So, who would dive with me as an instabuddy?
As others may say, up to the point you included buying the beer, I was skeptical. But, with the post-dive beer thrown in, 'Yes.' On a serious note, the answer is a guarded 'Yes', and here's my thought process. My primary goal as a dive buddy is to not be a burden to the diver I am buddied with. So, although I even said in another recent thread, about new gear, that if the diver showed up with a cheap, low performance octo, I probably wouldn't want to dive with him, I overstated that aversion to make a point to that OP. I plan to be self-reliant on any dive, and I do not plan to have to share my buddy's air, so I honestly don't care whether you have an Air2, or a cheap slimline octo, or no octo. I don't care if you dive split fins, etc. Certainly, you would come across in the pre-dive conversation as someone who is reasonably 'with it' and I would have no particular reservation about diving with you after that conversation.
What MIGHT cause me to say, 'No'? If I happen to be on a boat that REQUIRES I dive with a buddy, and you tell me '
If the computer fails I end my dive . . . ' - I have no desire to lose a dive because you decide to go streamlined / cheap / whatever. The problem for me is that, if I accept responsibility as your dive buddy, I would feel an obligation to end the dive with you. Years ago, my son and I were paired at the last minute with an insta-buddy who turned out to be an air hog (and was diving an AL80, while we were diving HP120s). We were diving a wreck off the NC coast at 115' that is subject to shifting conditions and has a narrow 'window of diveable opportunity'. Not too long after we descended to the wreck, with him having already held us up at the surface to fix a gear issue, he signals that he was down to 800 psi and was going to ascend. I made a (in hindsight, bad) call for my son and I to go up with him, since we were planning to dive the same wreck the next day, and I was a bit concerned about having a buddy, at 115' who was down to 800 psi, going up alone. The ascent was fine, he apologized afterward for having us curtail our dive. The next day we were blown out, and I have never been able to get back on that wreck. Yes, that was really my fault, for the decision I made, not necessarily his for being an air hog. But, it has colored my willingness to dive with insta-buddies ever since.
Similarly, if we are on a boat that REQUIRES buddy teams, I don't want to have you end the dive - for what I consider a completely preventable (i.e. not having a back-up SPG) reason - and then me continue the dive until I was ready to ascend, only to be chewed out by some mate / captain for violating their rules.
So, based on what you said, I would probably say, 'Yes', but my answer would also depend on the rules of the boat, and our mutual understanding of our obligation to each other. Frankly, after talking with me, you might decide that you don't want me as your insta-buddy after all.
