Scuba Refresher

with Hydronauts


If you have not been diving in 12 or more months, have forgotten a few diving practices, or just need a reminder on how to properly set up your equipment, we suggest it is time for a Scuba Refresher.

One of our Instructors or Divemasters will do a short workshop to refamiliarize the scuba academic principles with you before reviewing the equipment setup. You will then spend some time in our purpose-built training pool putting those principles into practice. 

Here at Hydronauts, we tailor your Scuba Refresher to what you do and don’t remember while confirming your safety protocols are well practiced. Our Refresher takes about 2-3 hours and is best completed the day you arrive on the island or the day before you’d like to go diving on the boat trips with us. 

We encourage everyone to dive as safely as possible and look forward to doing some fun dives with you after you complete the Scuba Refresher.
