I see the SA bashers are out again with their same lame dis-proven arguments.
Exactly
where did you disprove the calculations that show a SA would not have sufficient gas for a diver below 90' with an accelerated SAC?
You are entitled to your
opinion, but please don't rubbish or insult those members who opt to express theirs - especially when those opinions are substantiated.
As an AOW qualified diver, with sub-50 dives, I would question if you've had exposure to the gas management theory used to critique the capabilities of SA. I would also doubt that you have sufficient experience of scuba emergencies from which to understand the perspectives of those divers who disprove of micro-cylinder air redundancy.
SA marketing preys on novice divers. Point proved.
To recap, for those that don't pay attention:
1) Panicked SAC
No need to panic when you have enough gas to surface
Ignorance is bliss. Most scuba fatalities are avoidable, but panic causes additional problems to unfold. You doubt the reasoning behind calculating emergency scenarios based upon an elevated rate of breathing? I've yet to find a human being whose heart doesn't beat faster in a life-threatening scenario. If you feel you are otherwise, then you need a reality check.
2) I can CESA from 60' (but SA is too little air)
So, the debate would then ask...
why do you need a SA?
3) Full breath gives you 30-60 seconds (what if you dont get a breath?)
If,
for any reason, you didn't feel capable of conducting CESA from your planned diving depth, then you should have an
adequate supply of redundant air.
Full breath or not, the diver should be able to ascend for 1 minute without further air.
Besides, there are very few scenarios that would leave a diver with no breath and no warning.
4) All kinds of scenarios where SA would not work none of them 60' max dives with a buddy in clear water.
Yes, because a Spare Air is pointless in perfect conditions, shallow water and with an attentive buddy. The debate exists if you need
adequately sized redundant air for those scenarios where you couldn't reach the surface via CESA and where you may not rely on a buddy to air-share.
5) I'm too experienced or good for SA. Fine, don't use one.
I've not seen that written on any thread concerning SA. I think you have interpreted that. You have interpreted wrongly. Don't be insecure of other people's experience. If I join a motorcycle or climbing forum, then I would respect your advice. Don't let you ego drag you into close-mindedness.
...ask yourself why these other people bother on every SA thread to argue ad naseum against SA? Some type of agenda.
I dive every day. It's my job. I take my safety very seriously. I wouldn't use SA, for the reasons I have already expressed. As a dive educator, I take safety education very seriously. That is my agenda.
The people you are labelling as 'SA bashers' just happen to be a wide cross-spectrum of divers with significant experience in this field. In contrast, your experience and education in scuba diving is minimal and at novice level. Perhaps that might cause the slightest inclination to self-examine your stance?
What's more...the random bad-mouthing of people with opposing view points illustrates a very crude and unsubstantiated understanding. If you cannot debate factually, based on reasonable evidence, then please don't resort to childish name calling.
