TDI Extended Range Diver

TDI Extended Range Diver Course: Push Your Limits to 180 Feet

Ready to explore deeper? The TDI Extended Range Diver Course provides the training to plan and execute planned decompression dives down to 180 feet (55 meters) using air or nitrox as your bottom gas. This challenging course focuses intensely on the advanced planning, gas management, and problem-solving skills required for operating at these depths, including managing the effects of narcosis.

This course builds upon your existing decompression diving knowledge and introduces techniques for utilizing multiple decompression gases.

You will learn about:

• Advanced Decompression Planning: Strategies for planning dives with significant decompression obligations.
• Gas Management: Calculating and managing bottom gas and two separate decompression gases.
• Equipment Configuration: Setting up your gear, including twinsets/sidemount and two stage/deco cylinders, for deep diving.
• Problem Solving at Depth: Addressing potential emergencies and equipment issues while managing narcosis.
• Buddy Rescue: Practicing rescue techniques applicable to deeper dives.

This program requires meticulous planning and execution, developing your skills as a technical diver.

Prerequisites:

• Minimum age 18
• TDI Decompression Procedures certification (or equivalent)
• Proof of 100 logged dives, with at least 25 dives deeper than 100 feet (30 meters)
• Current DAN Master level insurance (or equivalent dive accident insurance)

Required Equipment:

• Backmount twin cylinders OR Sidemount cylinders (with appropriate harness/wing BCD)
• Two (2) AL40 (40 cu ft) cylinders (or similar), oxygen clean, with regulators for decompression gas
