Technical & Advanced Courses
Technical diving is about extending your depth, duration, and safety envelopes by adopting redundancy, strict dive planning, and advanced gas mixtures. As a TDI Technical Instructor, I provide training that emphasizes safety margins, gas management, and critical thinking.
⚠️ Important Gear Policy
Please note: I do not provide any diving gear. All technical equipment (backplates, wings, technical regulators, double cylinders, decompression bottles, drysuits, harnesses, etc.) must be rented or owned by the student for the duration of the course. I am happy to advise you on local rental options and gear configuration choices.
TDI Advanced Nitrox
This course is the foundation of technical diving. It qualifies you to use enriched air nitrox mixtures from 21% up to 100% oxygen for breathing and decompression purposes, significantly shortening decompression times.
Core Skills Mastered:
You will learn to execute proper gas switches underwater, analyze and label custom nitrox mixes, calculate oxygen toxicity loads (CNS/OTU), and plan gas requirements for technical profiles.
TDI Decompression Procedures
Move beyond standard recreational no-decompression limits. This course teaches you to plan and execute staged decompression dives down to a maximum of 45 meters using nitrox or oxygen mixtures.
Why this course is essential:
Often combined with Advanced Nitrox, Deco Procedures teaches you to manage complex equipment (twinsets or sidemount with deco cylinders) and respond to failures (gas losses, regulator freezes, lost deco gas) when a direct ascent to the surface is not an option.
TDI Intro to Tech
Introduce yourself to the world of technical diving. This course is designed to transition recreational divers into technical configurations, offered exclusively in Sidemount configuration for streamlined flexibility and redundancy without committing to deep or decompression diving immediately.
What you will learn:
Technical diving concepts, dive planning, buoyancy control, horizontal trim, advanced propulsion techniques (frog and back kicks), sidemount valve management, regulator switches, and standard technical team communication.
TDI Sidemount Diver
Moving your tanks from your back to your sides offers unparalleled flexibility, redundancy, and streamlined movement. Popular for overhead environments (caves/wrecks) and increasingly favored by cold-water lake divers for safety and back-comfort.
What you will learn:
Proper adjustment of sidemount harnesses, positioning cylinders to maintain a flat horizontal trim, valve management, regulator switches, and handling independent cylinders in and out of the water.
