The equipment provided is better than you would thing.
I brought mask, flippers & wetsuit & was very pleased.
The dives are not all that challenging, but amazing nonetheless for the beauty.
& the dive masters were A+++
Do sign up for the dives as early as you can, they do sell out.
They do only 1 tank dive per day... the price is about (as I recall) the same as a 2 tank dive in the Carib or Coz. But that 30 or 40 minutes is truly a blessing....ENJOY!

PS: not all the dives are as good as the others. Some are merely ok. Ask & the folks here will be glad to advise
