Very impressive, I think my head would have exploded had I tried something like that. Who did you do your course with?
ProTec Playa. Rob Bartlett was my instructor with Toro assisting (who also happens to be one of the best guides in Mexico IMO). The only reason I got it done in that amount of time was because both are excellent instructors, and it was an individual course, so their time was directed fully towards me. They have two different teaching styles, and they look at things differently, so it was very beneficial to have two separate opinions and explanations of anything, so that my understanding was always complete.
I already had AN/DP and XR, so the equipment skills were a moot point. Someone without that background would probably have a much more difficult time, as they are constantly throwing failures at you. Every single dive except the demo dive I had some sort of "malfunction," and dealing with that stuff under the hood must be exceedingly difficult without that prior experience.
I will say the hardest part was unlearning bad habits. And my head definitely did explode one more than one occasion. They are very good at working your stress level to the point of failure so that you really understand how to work through problems, and they didn't pull any punches.
I'll be honest, I went in wanting to become a better diver, but not expecting to succeed. I knew the course was difficult, I knew the level of skill required was higher than I was capable of, and my only expectation was to improve. It was a very steep learning curve, and in the end, the ticket was just icing on the cake. The benefit really was in the overall increase in my skill level.
T-Dub, I didn't mean to sound disparaging, I reread my comment and realized it could be taken as such. The best thing you could do is bite the bullet and take the Fundies course, instead of spending the money on doing a bunch of local dives and potentially developing bad habits that you'll have to overcome during the course. Remember, practice doesn't make perfect, perfect practice makes perfect. I was a great open water diver beforehand, but I just didn't know what I didn't know, and a large part of the first couple days was getting rid of all those bad habits I'd developed. If I could have replaced my 50 previous dives with one Fundies course, it would have payed dividends an order of magnitude higher.
