Technical Diving
Technical dives starting Summer 2026—training, skills, and pathways beyond recreational limits
Welcome to our Technical Dives (Starting Summer 2026)
If you’re ready to move beyond recreational dive time limits and prepare for deeper, more complex dives, our technical training is built to develop the equipment knowledge, procedures, and in-water control you’ll need as you progress.
Intro to Tec (TDI)
Our Intro to Tech (Introduction to Technical Diving) course introduces the diver to the equipment, skills, and expertise required to transition into technical diving.
This course is required as a preparatory course for our Advanced Nitrox and Decompression Procedures courses.
Objective: Familiarize students with technical gear configurations, enhance open water diving skills, and introduce advanced gas planning techniques within a no-decompression context.
Skills covered include:
- Technical diving equipment
- Equipment streamlining and configuration
- Line reel techniques
- Lift bag deployment as a contingency up-line
- Anti-silting finning techniques
- Advanced propulsion techniques
- Buddy assistance scenarios
- Buoyancy and trim exercises
- Situational awareness
- Gas depletion drills
- And more
The skills you will learn during this course are guaranteed to challenge you, make you a more comfortable and competent diver, and a more dependable buddy as you plan for deeper and more complicated dives.
Decompression Procedures (TDI)
Our Decompression Procedures course is designed for the diver who wishes to learn how to properly plan and execute dives exceeding recreational dive time limits.
This course examines the theory, methods, and procedures of planned stage decompression diving.
Objective: Train divers how to plan and conduct a standard staged decompression dive while not exceeding a maximum depth of 150 feet.
You’ll be introduced to the most common equipment requirements, gear set-ups, decompression techniques, and decompression mixtures (including Oxygen and Nitrox).
Advanced Nitrox (TDI)
Our Advanced Nitrox course is designed for the diver who wishes to use gas mixes containing elevated percentages of Oxygen as either their primary diving gas or as a decompression gas.
This course builds upon the Enriched Air Nitrox course and examines the use of EAN 21 through 100% Oxygen for optimal mixes to a maximum depth of 130 feet.
Objective: Train divers in the benefits, hazards, and proper procedures for utilizing these mixes for dives not requiring staged decompression.
Why use mixes with higher percentages of Oxygen?
- As a primary gas in shallow depths: Nitrox mixes greater than 40% allow substantially longer bottom times while greatly reducing your Nitrogen loading, thus reducing your DCS susceptibility.
- As a decompression gas: Mixes up to 100% Oxygen can be used to shorten your decompression obligation, or during recreational diving profiles, to provide an added safety margin by increasing Nitrogen out-gassing during your safety stops.
Best of all, our course can be completed using single or double tank configurations.
