Took the intro to Scuba class. There really was no instruction, per say. More of a reading of all disclaimers. We then had a 45 minute wait before pool time began and because they only have enough for half the class to go in at a time, we sat around for 30 minutes(boring). Was fun once we got it, but it bit nasty to have to use a respirator that someone just got done using(they don’t clean ‘em up after the first wave). Worth trying if you haven’t scuba’d before but otherwise, meh.
