We keep it personal: small groups with max. 5 divers per guide – or private dives on request. Experienced buddy teams are welcome to explore the dive site independently after the dive briefing. Certified solo divers with proper equipment are also allowed to dive solo.

To ensure safe and compliant diving, please bring the following documents:
1. Certification Card (Physical or Digital)
Your diving certification from any recognized agency (PADI, SSI, CMAS, NAUI, RAID, etc.). We accept all internationally recognized certifications. While we can verify many agencies online if we know your name and date of birth, it's much easier if you simply bring your card with you.
2. Logbook
Your dive logbook is required to verify your experience. This is especially important if you want to dive the HTMS Chang Wreck: As an Open Water Diver, you must provide proof of at least 25 logged dives including dives deeper than 18 meters.
⚠️ Important: No proof of experience = No wreck dive. The HTMS Chang sits at 26-31 meters depth and requires documented deep diving experience.
3. Medical Clearance (if applicable)
Start with our online Diver Medical Self-Check. If the result says a physician’s evaluation is required, download the Medical Questionnaire PDF and bring the signed dive medical clearance before diving. Your safety is our priority, and we strictly follow international diving medical standards.

Yes, absolutely! We recognize all internationally accepted certifications, including CMAS, SSI, RAID, PADI, NAUI, and others. As a CMAS 1★ diver, you're welcome to join our fun dives or training programs. If it's been a while since your last dive, we may recommend a refresher.
Important: CMAS certifications cannot be verified online, so please don't forget to bring your certification card and logbook with you.

If you haven't been diving in the last 12 months, we strongly recommend a refresher course. This ensures your safety, boosts your confidence, and allows us to give you the best diving experience. It includes theory review, skills session, and two easy dives – no pressure, just comfort

Unfortunately, no. Since the HTMS Chang is a deep dive, it must be done as the first dive of the day due to decompression safety. A refresher (scuba review) should never be combined with a deep dive. We recommend diving for two days: Day 1: Refresher with two dives at easier dive sites. Day 2: Dive the HTMS Chang.
