TDI Trimix Diver

The TDI Trimix Diver is the first step away from using air as a back gas. The main aim of this qualification is to teach you how to use Trimix safely through the use of established procedures and diving techniques.

TDI Trimix Diver:

• Teaches you to use Trimix
• Extends you depth limit to 60 meters.

Trimix combines helium, oxygen and nitrogen, which is designed to lessen the effects of nitrogen narcosis at depth, as well as to reduce the risk of oxygen toxicity.

Advanced physiology will be covered by this course, as will gas management, decompression techniques and in-water diving skills.

This course is taught on a twinset using two stage cylinders for staged decompression dives.

While the course requires only 5 dives to complete, here at Scuba Seekers we believe 1 or 2 extra dives are incredibly beneficial to maximise student confidence and safety. If needed, these additional experience enhancing dives are included in the price of the course.

TDI Extended Range vs Trimix Diver

If you are a certified TDI Decompression Procedures (TDI Decompression Procedures) you can choose between sign up for Extended Range or directly for Trimix Diver.

Extended Range is a very rewarding course and a useful continuation of deco training. Deep dive with air as your back gas is a valid option, specially in areas where helium is not available. But if you are planing to dive in challenging environmental conditions -for example cold water, limited visibility or a physically demanding dive- our recommendation is to learn to use mixed gases from the beginning and join the Trimix Diver directly.
