Two friends are currently getting certified and confided in me they felt pretty anxious in their first pool session and asked me how they can get more "comfortable" in the water. I know it takes time, time and more time in the water. But I don't want them to bail on the course so I've been working with them in our local high school pool with just mask, fins, and snorkel. We've been practicing different kicks, doing laps, turning around, keeping one's hands from flailing, etc. We just slow everything down and work on breathing control and so on. We dive for golf balls in the deep end and collect as many as we can on one breath of air. We did that in my YMCA class back in '79 and I feel it made me more comfortable and confident in the water. In fact, we did not even move on to scuba gear until a couple weeks into the course and spent the water time swimming, snorkeling, floating, diving down to retrieve things, etc all just to get comfortable. Are there other suggestions or general advice I can pass along to them about getting more comfortable? Thanks.
