Do you Spearfish? Do you freedive? Do you want to? People die freediving, and it's 100% avoidable. Aaron offers classes that will train you to dive deeper, but most importantly, safer. You'll learn what's going on during a freedive. You'll be able to stay alive yourself, but will also learn how to keep your buddy safe while you two dive.
