“The dive master was amazing! I was trying to quit when I did the refreshment course but then the dive master kept encouraging me and then I had a few fun dives with her, she's very attentive and considerate throughout.”

Safety practices on record

We found no explicit information about safety practices — oxygen & first aid, dive insurance, divers per guide, dive briefings, equipment servicing, and certification agency — on this operator's website when we read it on 2026-08-24.

Many shops that run dives carefully still publish nothing about how they run them, so this says something about the website, not about the diving. Ask them directly before you book.

Themes across the reviews Google returns — at most 5 per place, picked by relevance, not at random. Not independent reports, and not enough reviews to tell you a shop is safe.

This is not a safety rating. It records what an operator publishes and what its reviewers happen to mention — nothing here says an operator is safe or unsafe.
