About me: I was certified 6 months ago, bought a complete drysuit scuba gear set (brand new), and went on a single 2-day Catalina boat trip. After experiencing months of symptoms, 2 ENT consultations, and CT scan, I was diagnosed with Semicircular Canal Dehiscence and medically prohibited to dive. See my other posted items for sale (I would love to sell everything together). I’m planning to keep my mask, snorkel, fins.
