Here is an attempt to re-direct the discussion. I will try one bite-sized piece so that the debate can remain focused.
Question:
- Is practicing a blind swim (i.e., with your mask removed) underwater while being led by your buddy an essential skill?
- Should it be attempted in the pool, in open water, or never?
- At what level of training should this skill be required?
- Why?
- What agencies teach this skill?
My opinion:
- Yes;
- At least in the pool, possibly in open water depending upon the skill and comfort of the diver.
- Basic OW;
- Perhaps this skill is more critical in cold water diving than in warm. In cold water it is very hard to keep your eyes open without a mask, so in the case of a mask mishap you will be for all intents "blind." Your buddy would have to retrieve your lost mask, replace it with his spare, or help you surface. In all cases, relying upon someone's assistance while not panicking is essential, lest you go rocketing to the surface or sink.
- Not sure.
Yes
Yes to both
Basic OW
In addition to diver comfort I feel it reinforces proper buddy skills and positioning. In the pool I require it while air sharing and while buddy breathing. I first will demo it with one diver and then have the buddy pairs do it. Each diver gets a turn at each role. In my AOW class they do a 100 ft horizontal air share no mask swim at 25-30 feet and ascent to the surface.
