A Supervisor is a similar rating to Divemaster, but the student gains more experience and the ability to lead more advanced dives which is an in-demand skill for technical divers.  TDH believes in incorporating skills and stress management into every diving course to develop safe divers, DiveMasters, and instructors. The Advanced Recreational Trimix Supervisor Program has three tracks for students—as determined by the electives the student chooses— between back mounted (traditional SCUBA), Sidemount, and Closed Circuit Rebreather. This program results in students receiving an Advanced Recreational Trimix Supervisor rating with an optional specialty in Sidemount or Closed-Circuit Rebreather.
Closed Circuit Rebreathers are becoming increasingly popular with recreational divers because they open new and exciting options to dive deeper and/or longer.  As a result, there is a growing demand for Closed Circuit Rebreather Supervisors who can lead dives at resort locations around the world.  Likewise Sidemount diving is becoming increasingly popular around the world with both recreational and technical divers due to its numerous benefits both for streamlining a diver’s gear outfit as well as decreasing physical strain on a diver’s back. MDD’s Advanced Recreational Trimix Supervisor program takes a student with no dive experience and gives students the confidence and skills necessary to lead dives at greater depths and with greater skill, exceeding the industry standards.

TDH's Advanced Nitrox Instructor Program takes students certified supervisor (or equivalent) and turns them into confident instructors who can teach traditional back mount and side mount diving configuration certifications at greater depths. This program utilizes both classroom and extensive in-water skills development.  TDH believes in incorporating skills and stress management into every diving course to develop safe divers, and professionals. As students advance through the program, they will have opportunities to assist in instruction and develop their skills while receiving constant feedback from our course directors and instructors.
This course also includes certification as an equipment technician, gas blender, and gas blender instructor ratings. These ratings are very highly valued in the dive industry and is a vital skill for independent technical divers who likely will not have a readily available maintenance technician or blender.
Upon successful completion of this program, students will receive their Advanced Nitrox Instructor rating and certificate from the certifying agency.  They will also receive their Dry Suit Diver, Equipment Technician, Trimix Gas Blender, and Gas Blender Instructor Ratings.

As closed-circuit rebreathers become more popular in the recreational market, there is growing demand for closed circuit rebreather instructors.  Closed circuit diving is unique in comparison to open circuit diving because instructors can only teach the specific closed circuit rebreather model they are certified to instruct.  Over the course of program students will learn how to safely and competently instruct and service their chosen closed-circuit rebreather model, lead students on dives to 200 feet on Normoxic Trimix, and naturally progress in their skills and confidence until they are ready to become closed circuit rebreather instructors in accordance with industry standards.
Because closed circuit rebreather diving is more dangerous than open circuit diving,TDH’s standards for the CCR Instructor Program are extremely stringent to ensure only highly competent divers are submitted for certification to the certification agency and the rebreather manufacturer.  Prospective students should note
that they must achieve a score of 95% on every skill and test in the Instructor Development Course in order to be submitted to the certification agency and the manufacturer for approval as an instructor.  Upon successful completion of the program, students will receive their Normoxic Trimix diver certification, and their CCR Instructor rating, and manufacturer certificate for their model of rebreather.

This program is for students who want to instruct closed circuit rebreather divers on how to dive up to 333 feet.  Dives at these greater depths open new terrain and less explored dive sites, but it also requires greater responsibility and training to instruct divers safely to this depth.  This program will give students the confidence and skills necessary to be a successful CCR Normoxic Trimix instructor at dive locations around the world.  To enroll in this program, students must already have one of the six closed circuit rebreather models that MDD offers in its other programs and be an instructor for that model.  Upon successful
completion of this program, students will receive their CCR Normoxic Trimix Instructor rating and certificate from the certification agency for their model of rebreather.
