Class 4 (Pool Session 3)
Lecture
We primarily discussed some of the problems that can occur if surfacing to quickly, including, but not limited to, DCS. Of course, we spent time going over how to avoid having problems in the first place, and reinforced the mantra of breathe continuously. We also spent part of the lecture time going over the difference between anchor diving--when a dive boat is anchored--and drift diving when the dive boat isn't anchored. As always, good stuff...
Pool
We assemble our gear and changed as soon as we completed the quiz. It is really becoming easy to get the gear pulled together and assembled correctly. Once everyone was there and ready, we learned how to do a giant stride entry--from the deep end of course. Everyone then did a giant stride entry, and I believe we were all successful...and then we swam to the shallow end of the pool to learn the skills for the evening.
The first skill we were taught was the emergency buddy tow. After it was demonstrated, we towed each other to one end of the pool and then our buddy towed us back. It rememinded me of learning to tow someone back in lifeguard class, only much easier to do with fins.
The next thing we did was buddy breathing. We saw it demonstrated and then we did it above water, each buddy giving the out of air hand signal and the other buddy moving to their aid. The key things that our instructor was looking for was the handing of the "octopus" to our buddy, the grasping of the right shoulder strap with the right hand and the elevating the BC inflator over our head with the left hand. We then repeated the process under water in the shallow end, again with each buddy taking their turn to be the one w/o air. The next step was to head to the deep end of the pool and repeat the process one more time.
After we successfully completed the process, we had free time to practice what we had learned on our own: neutral bouyancy, mask clearing, pressure equalization...and just spending time under water getting used to breathing continuously.
The last thing we did for the evening was to exit the pool via the ladder with our gear still on...realizing of course that the pool ladder is stationary and a boat ladder is not, but it still helps us to learn what it will be like to try to climb a dive ladder wearing gear.
All in all, things are going very well, IMHO, and I am still very much enjoying the process! The instructor told me and my buddy we were doing a good job with the learning/demonstrating of the skills...and that's a good thing to hear. Next class is Wednesday...and we will continue to learn new skills in preparation for our first "real" dive...which will happen on Sunday...more details to follow after Wednesday's class.
