    Noob question, but I have my SDI scuba... When I went through that training, was told to come up / go down slowly. Long story short, I bought free diving fins, and wanted to swim down 20-30feet several times for photography (just by holding my breath).

    I assume, since I'm not breathing and but rather holding my breath, I'm fine?

    I guess what I'm asking is if I want to go snorkeling, and swim down 20-30 feet, then quickly come up (in one breath), am I good?

    Decompression isn’t a consideration when snorkelling or freediving. However, if you’ve been diving early in the day there could be an issue because of micro bubbles.

    You can go down and up as fast as you want to.

    Unless you freedive deep and frequently, you don't have to worry about decompression. (Yes, extreme freedivers do have DCS considerations.)

    However, you DO have dangers, such as blackouts, to worry about. I STRONGLY suggest you take a freediving safety class, where you'll learn the dangers and how to avoid them (mainly through proper buddy procedures, one up and one down and knowing how to revive a blacked out diver).
