Some people, especially online, will complain that specialty classes are a waste of time in general. I can’t tell you how useful all the classes I’ve taken have been so far! And in looking over all the offered classes through the various scuba organizations, every single one of them sounds like a fantastic learning opportunity.
The Peak Performance Buoyancy class in particular has been the most useful for myself. Since taking the class, I’m not perfect by any means, but I’ve dramatically improved my ability to move around underwater. That means I can get super close to some amazing things without worrying that I’ll crash into them!
I really enjoy seeing the small things, like little sea creatures and tiny surprises, and now I can do that so much more easily. Every dive has become a new opportunity to practice my skills.
