Twiddles:Wow... all I can say is eye opener. Assuming of course that Im hearing honest opinion:
Minority = Aid if you are able.
Majority = Aid only after you have evaluated the risk. Disregard what you were taught to do in OW and AOW evaluate the situation determine your ability to control the situation and then and only then offer aid.
Solution wear a secondary air supply.
For those of you that would help if able, thank you, know that I will always help if able. If I am unable, I am sorry. For the rest of you I pity you. You may be better trained but somewhere in that process you lost some things. Maybee you feel you gained a better understanding of how you should be, objective, impartial, an evaluator. Based upon the answers I have seen, you have lost more than you gained.
...you write off the "majority", remember that the competent diver will not ( as Mr. Ferrara stated ) place themselves into circumstances ( like "Pod Diving" ) where they may be forced to reactively evaluate. Rather, they will conduct themselves in a manner well detailed by the many fine divers / contributors to this discussion, thereby minimizing the odds that they will personally encounter the circumstances that Mr. Snyderman found himself in.
There are others like me who, whenever they are diving ( topside or below ) remain on the lookout for possible "situations", while continuing to perform as a good buddy to their partner. I make this reality clear to my buddy prior to entry, & we discuss our potential response actions should an intervention be prudent. Such proactivity need not be the preserve of diving leaders; rather, I encourage all divers to act as such, within the limits of their personal capabilities & limitations. In time one learns to "read" the behaviours going on around them with a reasonable degree of accuracy. Sometimes it is as simple as paying a visit to a diving pair who appear to be heading for problems, having a subtle look into their eyes, & evaluating their response(s) to you. At other times a more aggressive response is indicated.
I much prefer proactive evaluation to reactive evaluation - it makes the odds for a happier ending much improved.
