If you’re into technical diving then you know that to extend your depth range you need to use trimix – a blend of helium, oxygen and nitrogen. The Tec Trimix 65 course introduces you to using trimix down to a maximum depth of 65 metres/210 feet. There are advantages to using three gases, but you need to know how to do it right. Earning the Tec Trimix 65 certification makes deeper exploration a reality.

You’re qualified to enroll in the Tec Trimix 65 course, if you:

• • Are a PADI Tec 50 diver

• • Have a minimum of 100 logged dives

• • Are at least 18 years old

• • Have a Medical Statement signed by a physician within the last 12 months

Tec Trimix 65 course topics include:

• Trimix diving depth ranges
• Exposure planning
• Selecting a mix
• Argon inflation systems
• Handling three or four decompression cylinders
• Decompression models
• Emergency procedures
• Decompression software and multi-gas computers

You’ll use full technical equipment and you may use a technical sidemount configuration, plus two stage/decompression cylinders. Your Tec Trimix Instructor may suggest other equipment.
