I did it and it was great - well for me!! My wife tried, but as many of you predicted, it was simply too much for her to absorb so after going down 5-6 feet and having trouble clearing her ears she just decided to surface and wait on the boat. The instructor tried to convince her to keep trying but she really wasn't interested. After making sure she got back on the boat, we went down to about 10 feet (which took longer than I expected because I was having to clear my ears every 2-3 feet). Once at 10 feet, we practiced some skills (clearing mask, clearing regulator, locating regulator if it comes out of your mouth, breathing from someones 2nd mouthpiece if yours stopped working, etc. etc.). Before even getting on the boat we went over some classroom stuff and signals and things like reading depth gauge and pressure gauge, clearing ears, etc. etc. At 10 feet hung out there for a while. After a while and seeing that my pressure guage was even with the instructor we decided to go down to about 40-45 feet and hung out there and saw plenty of fish, seahorse, starfish, etc. etc. So all in all it was good and my wife still wants to try again, but AFTER taking all our classes and training here in the states before our next vacation.
