How Deep Can Scuba Divers Go? Your Koh Tao Depth Guide with Master Divers
How deep can scuba divers go? It is a common questions many of our customers here at Master Divers here on Koh Tao ask. With crystal clear water, warm tropical conditions and dive sites suitable for every certification level, the island is the perfect place to learn about depth limits and how they relate to your training and experience.
In this guide we look at depth limits in both recreational and technical diving before bringing it back to what matters most for divers here on Koh Tao. We also explain why staying within your training is essential for safe and enjoyable diving.
Recreational Diving Depth Limits
Recreational diving has clearly defined depth limits set by training agencies like PADI, and these limits exist to keep divers safe while ensuring you get the most enjoyment from your dives.
Open Water Diver certification
Depth limit: 18 metres
This is the most common entry level certification on Koh Tao and allows you to explore beautiful sites like Twins, Tanote, Japanese Gardens and White Rock.
Advanced Open Water Diver certification
Depth limit: 30 metres
Once certified, you can enjoy deeper sites such as Chumphon Pinnacle, Southwest and Shark Island which is famous for schooling barracuda and seasonal visits from whale sharks. This certification also opens up about 90% of the dive sites world wide for you.
Deep Diver specialty
Depth limit: 40 metres
This is the maximum depth for recreational diving. Koh Tao has several sites where qualified divers can train and practice deeper skills safely.
How Deep Can Technical Divers Go
Technical diving goes beyond recreational limits and requires specialised equipment and extensive training. These dives can involve mixed gases, decompression procedures and redundant systems.
Here are some typical tech depth ranges to give you perspective:
Technical diving with decompression procedures
Depths often range from 45 to 50 meters depending on the diver’s training.
Trimix diving
Using a mix of oxygen, nitrogen and helium, trimix divers can exceed 60 to 100 metres or more with the correct certifications and equipment.
Extreme technical expeditions
The deepest dives in the world exceed 200 metres although these are highly specialised undertakings completed by very experienced teams and are far beyond what most divers will ever do.
These depths are mentioned to show what is technically possible. The key takeaway is that significant training, planning and equipment are required once you move outside recreational limits.
Bringing It Back to Recreational Diving on Koh Tao
While technical diving can reach impressive depths, most divers on Koh Tao are here for the incredible recreational sites that sit well within the 18 to 30 meter range.
