❓ How long does a dive last?

The duration of a dive depends on several factors – especially depth, your air consumption, and local conditions.
At Chang Diving, we use standard S80 aluminum tanks (11.1 liters / 80 cuft at 200 bar), which corresponds to about 2220 liters of breathing gas.
On average, around 1665 liters can be actively used while diving, with the rest kept as a safety reserve.

Under normal conditions, the typical dive time is 50–60 minutes. Depending on breathing rate, depth, and current, actual dive time can be shorter or longer.
💡 Tip: Calm breathing and shallower depths extend your underwater time – we explain why in this article
🔗 Why Air Consumption Matters While Diving

❓ How deep can I dive?

The maximum allowed dive depth depends on your certification level:
• Open Water Diver: up to 18 meters
• Advanced Open Water Diver: up to 30 meters
• Deep Diver Specialty: up to 40 meters – this is the maximum limit for recreational diving

Deeper than 40 meters or dives with planned decompression already belong to technical diving and require special training.
For Try Dives, we stay in shallow, safe areas of around 5 to 12 meters.

❓ Do I need prior diving experience to dive with you?

No, for a Try Dive (introductory dive) you don’t need any prior experience – perfect for beginners!
Our experienced dive instructors will guide you step-by-step, from your first breath to your dive in the sea.

If you wish to complete a full diving course like the Open Water Diver, you should be able to swim and be in normal physical health.

What time will we return from the dive trip?

Return time depends on several factors – the dive sites we visit (travel distance), the number of dives (2 or 3), and how many divers are on board. For example, a group of 10 divers takes more time than 5.
In general, we return to Klong Prao Beach between 1:00 PM and 4:00 PM. Don’t forget to consider the transfer time from the beach back to your hotel.

Visibility around Koh Chang averages between 8 and 20 meters – depending on the season, current, and dive site.

❓ Do I need special dive insurance?

Special dive insurance is not mandatory but highly recommended – especially if participating in courses or deeper dives.
Many travel insurance policies do not cover dive accidents or only do so partially. With dive insurance from providers like DAN Europe or Aqua-Med, you are well covered.

For a Try Dive, the minimum age is 10 years. For certified courses like the Open Water Diver as well.
