SCR as a bailout technique is taught and is part of the standards. The question I guess is is the method of how to determine SCR deco part of the standards?
if it isnt then IMO it should be - And if your right then thanks for correcting me without bringing conflict and deriding me
Mike I tend to agree with you that SCR mode should be covered more in-depth.
My thinking on this is Mod 1 divers are usually certified to dive to around 40m.
So here is the scenario:
A diver plans a dive to 40m for 25min resulting in 10 min limited deco obligation (planed using v-planner using my personal config) if at the last minute of the dive they had to bailout that would result in an increase of runtime from 40min to 73 min. quite a big jump considering the amount of bailout gas some dives choose to carry and the stress that could be encountered. My personal requirements would call for around a 1000 liters of gas to complete that deco, that’s assuming its not a CO2 issue.
So introducing SCR in this case could avoid a diver surfacing and missing all that required deco due to inefficient gas planning. Some of the divers I have had the pleasure of diving with have never even considered this eventuality and would have been faced with lengthy deco obligations with no reel understanding of decompression diving techniques.
A more in-depth discussion should at least take place during the academic session of mod 1 training even if the diver is far away from making this dive having just passed their course. soon they may be thinking about hitting these depth without considering the bailout gas requirements.
Just my two cents worth.
