@NetDoc: I'm not comfortable being as far as a 10 second swim away from my buddy. I guess I have "bigger issues than buddy management" (whatever that is). Are you implying that I'm inadequately trained and/or not comfortable in the water?
You answered your own question before you even asked it!
Position one buddy pair a "10 second swim" away (let's say it's a "hard" 10 second swim) from the other.
That defeats the whole point of teaching them situational awareness. They have to
FIND and then get to their buddy within that 10 seconds. Quite often when I signal the diver, their buddy is just a bit above them. Since they don't think in 3D, they seldom think to look just above them. In darker water, their disorientation is almost immediate and they have less time to do it in.
I think the 5 or 10 second rule can lull the OW student into a false sense of security.
You say that ONLY because no one has tested you on it. It's a wonderful exercise and builds situational awareness.
Once, I had a class come up to a small rise in the reef. One student went one left and the other went right. I popped my fist (a loud signal to look at me) and both looked at me, but couldn't see each other. I was able to give the "Where's your buddy?" sign to them both simultaneously. One turned around and went back and the other went over the rise and both were moving so fast that it seemed to take forever for the one to catch up. Now, you don't think some learning took place there?
What's the golden rule for a lost buddy?
Stop, breathe.
Listen, look and breathe.
Ascend a few feet and look around you 360
o and don't forget to breathe.
Bubbles get bigger as they ascend. The chances are that you can see your buddy's bubbles as you ascend increases as they increase.
Look for no more than one minute and head to the surface slowly: turning, looking and breathing all the while.
If your buddy is doing the same thing then you'll see each other on the way up or on the surface.
My intent was not to cajole you or intimidate you. It was a serious question.
Nope. Maybe one day.
