Seems like a fair trade off for diving clear 72 degree water in Texas. Although for a family of 4 divers I am not sure I am willing to drop $1000 on course fees to fan the algae off the bottom of the lake unless I lived extremely close to it.
True, but a family of four will pat $130-160 at a scuba park for a two-day weekend at a murky lake. It just depends on how much you plan to dive. A lot of people take the course and then only return a few times if at all. They paid a lot of money for a bit of education, which may be worth it, but probably not what they had intended. Then there are others who return several times a year (or more) for many years. It's just like buying scuba gear. There's a significant upfront cost and the payoff is proportional to how often you dive.
