TDI Training Programs
Discover our technical diving training programs to develop your advanced diving skills with TDI standards
TDI Intro To Tech
Want to improve your diving skills? This course introduces technical diving concepts and implements dive planning at a technical level while remaining within recreational limitations.
TDI ANDP Advanced Nitrox Deco Procedure Combo
Want to go deeper and stay longer? This combo teaches you to dive to 45m and breathe any nitrox mixture from 22% to 100% Oxygen.
TDI Extended Range
After your ANDP course, go deeper without doing a full trimix course. This course trains you to dive to 55m on air and use decompression gasses up to 100% O2.
TDI Trimix Diver
Upon completion of your ANDP course, take the next step and go deeper. This course teaches you to dive to 60m and use multiple gasses to accelerate decompression.
TDI Trimix 75M
After finishing your TDI Trimix course, you will be ready for the next step: 75m. This course is the continuation of Extended Range training, allowing you to safely dive to 75m using various mixes of oxygen, nitrogen, and helium.
TDI Technical DPV
Learn to use Diver Propulsion Vehicles (DPV) in technical diving environments. This course teaches advanced DPV handling, navigation, emergency procedures, and gas management while using underwater scooters for extended range diving.
TDI Advanced Gas Blender
Master gas blending techniques for technical diving. This combined course covers both Nitrox and Trimix blending, teaching you to safely mix breathing gases for advanced diving applications. Learn industry standards and safety protocols.
Closed Circuit Rebreather (CCR) Training
TDI CCR Air Diluent CCR
Introduction to closed circuit rebreather diving using air as diluent. Learn fundamental CCR operations and safety procedures for recreational depths.
TDI CCR Air Diluent Deco (40M)
Advanced CCR training using air diluent with unlimited decompression capabilities up to 40m. Combines Air Diluent Deco (40m) and Air Diluent CCR (up to 30m) techniques.
TDI CCR Helitrox
Advanced CCR diving up to 45m using Trimix 20/35 (20% oxygen, 35% helium). Learn helium management and advanced CCR techniques with unlimited decompression capabilities.
