Scuba Review & Refresher Course in Koh Chang
Certified but haven't been diving for a while?
Our Scuba Review in Koh Chang is the ideal way for
certified divers to safely return to the water and rebuild confidence
before
fun dives, wreck dives or advanced training.
This one-day scuba refresher course is designed for divers who feel unsure about their skills after a longer break. Together with an experienced SDI, TDI or PADI certified instructor, you'll review essential scuba diving theory, equipment handling and underwater skills in calm, controlled conditions.
During the in-water session, we focus on buoyancy control, mask skills, regulator recovery, emergency procedures and proper dive communication. The pace is relaxed and adapted to your experience level – no stress, no pressure.
Our scuba refresher in Koh Chang includes 2 shallow training dives (max depth 12-18 meters) at calm, protected dive sites like Hin Raab South or Blueberry Hill in the Mu Koh Chang National Marine Park. Small groups (max 4 divers per instructor) ensure personal attention and a relaxed pace.
This scuba review is perfect if:
- You haven't dived for several months or years
- You want to prepare for fun dives or wreck diving
- You prefer small groups and personal guidance
- You want to refresh specific skills before advanced training
All refresher dives are conducted from our own dive boat and led by certified SDI, TDI or PADI professionals with extensive local experience.
If you're looking for a safe, professional and relaxed scuba review in Koh Chang, this course helps you feel comfortable underwater again – so you can fully enjoy your upcoming dives.
