Lynne, I don't have time to read read through every response in this thread but will when I have some time.
I'm sure several posters have listed GUE's Fundamentals class as their hardest. It was for me despite logging 100 OW dives by the time I signed up for the Fundies class. During the five day class I was shown the standard I had to meet but during most of the class I struggle to meet those standards. I was mentally beating myself up each day for not doing well during the dives. The last two days of class, I had dreams of the skills I was required to do for class while I was sleeping. I allowed the class to affect me which made it a hard class for me. I'd never seen such precision in the water column until I saw Bob Sherwood underwater and I wanted that precision so badly. In addition to the dives there was considerable amount of classroom knowledge to absorb every day. Up until that point, I'd never had a class that ran 12 hours or more per day.
Up until that point, I'd never watch a video of myself underwater while the instructor gave positive and negative feedback. I'd never had every propulsion or task scrutinized to such precision and detail as in my Fundies class. I'd never had to dive as a team, yes, I had buddies before but this was a whole different level of awareness during a dive, to not only think of yourself throughout the dive but to think of your team. From the time you entered the water until the time you exit the water, it was a team dive. The gas on my back was a team resource. That a-ha moment when your team gets it right and it clicks only hit me on the last day of class but when it did, it made up for the mental beating I gave myself for four days.
Fundies was my hardest class because of all the many *first* I listed above. I have been able to leverage off the many *first* for all subsequent training classes which is not to say those subsequent training classes were not hard but having solid fundamental skills allowed further training to build on top of it.
thanks for this post. I have been looking for an opportunity to take GUE Fundamentals, and will probably start looking a little harder. All of the classes I have taken have contributed to me being a better diver, but I have never had a class challenge me to make drastic improvements. I expect GUE Fundamentals to be both challenging and rewarding.
