Decompression Procedures

During this course you will learn to function as a member of a deep dive team and to plan and execute dives requiring more extended stage decompression. You will make training dives as deep as 55 msw/180 fsw while breathing air or optimized Nitrox and refine the proper procedures for making longer decompression stops utilizing a single hyperoxic decompression gas like EAN50 or EAN 75. The course will include hands-on experience with decompression planning software or accelerated decompression planning tables. You will gain the ability to prepare primary, contingency, and bailout plans. You will become experienced at evaluating conditions, anticipating potential problems, and applying the appropriate dive technique to achieve dive objectives.

Prerequisites: minimum age 18 years old, minimum 75 logged dives, certification in Deep, Stress & Rescue, Enriched Air Nitrox and Advanced Open Water Diver, Oxygen Provider, certification as an SSI Tech XR Technical Foundations Diver OR an SSI Tech XR Cave Diver OR an SSI Tech XR Technical Wreck Diver or equivalents.

Advanced Decompression Procedures

This course examines strategies for accelerated decompression using 2 or more stage cylinders. You are presented with the option of multiple Nitrox blends and you will learn advanced ppO2 management procedures to control CNS toxicity dose. Training dives are conducted to depths as deep as 55msw/180 fsw if certified as a decompression procedures diver (or as deep as 65msw/220 fsw if certified for Normoxic Trimix) using two or more gasses for stage decompression.

Prerequisites: minimum age 18 years old, minimum 100 logged dives, certification in Deep, Stress & Rescue, Enriched Air Nitrox, Advanced Open Water Diver, Oxygen Provider and certification in Decompression Procedures or Normoxic Trimix plus 30 logged air dives or normoxic Trimix Dives deeper than 30msw/99fsw and requiring at least two stage decompression stops.

Normoxic Trimix

You will learn the procedures for using Normoxic Trimix blends with any helium concentration and oxygen concentrations as low as 18%. Training dives will be conducted to depths of 60 msw/200 fsw and hyperoxic gas blends will be utilized to complete stage decompression stops.

Prerequisites: minimum age 18 years old, certification in Deep, Stress & Rescue, Enriched Air Nitrox, Advanced Open Water Diver, Oxygen Provider. Decompression Procedures or equivalent with a minimum of 100 logged dives including at least 10 deeper than 30 msw/99 fsw and requiring at least two staged decompression stops OR Certification as an SSI Technical Foundations Diver with at least 100 logged dives including at least 30 deeper than 27 msw/90 fsw and requiring at least 2 staged decompression stops.

Hypoxic Trimix

You will learn the procedures for using Trimix blends with any safe helium/oxygen concentration. Training dives will be conducted to depths as deep as 100 msw/330 fsw and multiple gases including hyperoxic gas blends will be utilized to complete stage decompression stops.

Prerequisites: minimum age 18 years old, certification in Deep, Stress & Rescue, Enriched Air Nitrox, Advanced Open Water Diver, Oxygen Provider. Normoxic Trimix or equivalent with a minimum of 150 logged dives including at least 30 deeper than 30 msw/99 fsw and requiring at least two staged decompression stops, 10 dives deeper than 50 msw/165 fsw requiring at least 2 gas switches.

Basic Cave

This course is the intermediate twin set stage between cavern diver and full cave diver. Divers will focus on simple linear penetration techniques that are extended well beyond the limitations of cavern diving.

Divers are limited to penetrations without major restrictions and within the limitations of their available gas supply. Both Extended Range and Cavern Diver are prerequisites. You must have either Basic Cave of or Intro to Cave as a prerequisite for full Cave diver.

Cave

This course is the next step for the Basic Cave Diver. The Cave Diver Course is a full penetration course for underwater explorers desiring to complete extended penetration dives in more hazardous conditions.

The diver will expand their skills to include more complex navigation methods completing circuits and traverses in addition to negotiating major restrictions and other environmental hazards. The Cave Diver is one of the apex courses in the world of extreme diving.

Technical Wreck Diver

This is a full penetration course designed for underwater explorers seeking to view the inner most reaches of both shallow and deep water shipwrecks.

Qualified divers may participate in penetration dives during training as deep as 50 meters with the only limitation being a planned deco schedule and the gas supply. The Technical Wreck Diver is the third and final apex course in the world of extreme diving.
