Hank49:I've seen it stated on this board that "a lot of instructors don't have good diving skills". I find this surprising. The year I did my IDC I also witnessed two others and in my opinion, all the candidates had good skills. We all had to demonstrate, and teach buoyancy by hovering Buddha style in 8 or 60 feet depth with no up or down movement. We were all living there on the island and diving every day, working with each other, so how could you NOT develop good skills? The candidates who failed the IE, unbelieveably, usually failed the Standards and Procedures exam...the open book test.
I guess it must be different if you do the whole OW thru IDC in quarries. ??
What in the world does hovering Buhhha style have to do with diving!? An ill-trimed person may have no choice but to hover Buddha style or some other similarly upright posture. If I was designing an IE the candidates would have to show me that they could maintain a horizontal position without kicking or skulling, and maintain it while swiming forward, backward, turning, ascending, descending, sharing air, replacing a mask, dealing with a free flow or just about any combination of the above. That's diving. Hovering buddha style or upside down might be fun at times but it's little or no indication of ones diving skill.
So in answer to your question...
...We were all living there on the island and diving every day, working with each other, so how could you NOT develop good skills?
You won't develop good skills if you aren't aware of what good skills are.
I guess I don't know where you're going with the comment about an IDC in quarries.
Not to pick on you but this really is just about a perfect example of what I'm talking about.
