What is the DSAT Tec 65?  

This new course opens up the advantages of trimix to the Tec 50 diver (or equivalent). After certification divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, with any trimix having an oxygen content of 18% or more up to a maximum of 65 metres. Five dives are included. Successful candidates may then embark on Tec Trimix 75 training.

Most people learn technical diving in backmount (both cylinders located on back), if you want to take this course and in sidemount (one cylinder located separately under each arm) and find out why side mount configuration is superior. Visit www.sidemountscubadiving.com for more information. 

Equipment Requirements?

• Double cylinders (minimum 12 l/70 cf each, with larger preferred) with isolator manifold or separate cylinders if using sidemount configuration.
• Primary and secondary regulators, one with two metre/seven foot hose (approx.) for gas sharing, and one with SPG
• Stage/decompression cylinders with regulator, SPG, mounting hardware and proper labeling/markings. Two per diver will be required
• Backup decompression cylinders as appropriate and required for the environment
• BCD and harness – redundant buoyancy control is required (double bladder BCD or dry suit if suitable for weight of equipment worn)
• Depth gauge/computer and backup depth gauge/computer
• Timing device and backup timing device
• Trimix decompression information (tables/trimix computer) and backup decompression information
• Exposure suit appropriate for environment and dive duration. (If students will use dry suits, they should be trained/experienced with their use in recreational and technical diving prior to using them for trimix training or diving.)
• Argon dry suit inflation or other inflation system as needed (students should not inflate dry suit with trimix)
• Weight system (if needed)
• Jon line (if needed for current diving environments)
• Inflatable signal tube
• Reel
• Lift bag (bright yellow or per local community practice preferred)
• Knife/cutting device and backup Slate Backup mask (optional)
• Compass Lights (optional)
• Drift kit (if drift decompressing)

What will I need?

Tec Trimix Student Manual and the Tec Deep Diver Manual (need a few weeks before the start of the Course to complete all Knowledge Reviews etc)
