Bill Rennaker told me that he made a very similar suggestion years ago for cave instructor training. He suggested that all instructors should perform a solo dive prior to being permitted to teach. At the time, his suggestion was also met with extreme resistance.
Why? Can it not be expected of a cave instructor that he can perform a simple cave dive on his own, from start to finish?
How is he going to take responsibility for others, if he is not even willing to be fully responsible for himself?
I would be interested in hearing why you consider the idea to be absurd? Surely there must be a reason for not liking the idea?
There should never be the situation where a diver cuts any corners, just because he has the added safety of a buddy or team. A lot of people do just that and the buddy or team becomes an excuse to get extra sloppy with the rules and gas management.
I've now had several people tell me about full cave certified divers, getting guided in Mexico and intentionally breaking thirds.
The motivation for this? Of course they paid a lot for the guide and wanted to get something for their money. With the guides using so little gas, they figured it would be ok and justified and considered him to be their mobile "fill station".
This is an extreme example, but I hope it gives food for thought.
It's time people accept responsibility for themselves, and for others that put their trust in them. A good diver should never be dependant on his team.
A good team consists of good divers that understand this concept. I believe solo diving can be used to shape the mindset and create good divers.
