Answer the questions honestly and, if in doubt, always consult with a medical professional. You can also have a look at the “Diver Medical” linked below for more details. A positive answer does not automatically disqualify you from diving but you do need to get a physician’s evaluation beforehand.
If your answer to all questions is NO you do not need to do anything.

① Download and print the “Diver Medical“, please read it carefully as you fill out and sign it.
② Take the Diver Medical (all three pages) to your physician for an evaluation. The medical must be dated and signed by both you and your physician to be valid.
③ Email us the Diver Medical (all pages) at least a week before your tour (or as soon as possible if your reservation is in less than one week). If you are not comfortable sharing the information over email, you can bring a printed copy with you the day you dive.

Frequency Asked Questions

I’m over 60 but my answer to all questions is NO, do I still need to send the Diver Medical?
Yes. The risk of serious injury when diving increases with age so we ask all divers over 60 to get a physician’s evaluation.

I’m a certified diver, do I still need to send the Diver Medical?
If your answer to any of the questions is YES or if you are over 60 years old, you need to send or bring the Diver Medical.

I have a Diver Medical from before, can I use that?
As long as your health situation is the same, you can use the form if it’s less than 12 months old. We only accept diver medical forms, either the same as those linked on this page or equivalent.
