As part of my new and now successful Advanced Dive certification we did a boat dive to see the grey nurse colony - Wow. Critically endangered with only 200-300 worldwide there must have been at least 20 here. What an experience!
NB I clearly have to fix the date on my gopro. This was taken yesterday not last year!
I remember in a much earlier life I used to scuba dive. But no camera. Pity.
Congratulations on your advanced dive certificate.
