TECHNICAL DIVER 2

TECH 2 | HYPOXIC TRIMIX

Technical Diver 2, or “Tech 2” (previously called Trimix 1), is the next step in our technical diving sequence, building on the skills the diver learned in Tech 1.   It introduces the diver to deeper depths and dive complexity, using hypoxic trimix and two decompression gases.


It's designed to continue the diver's pursuit of technical diving, giving them the training and ability to dive to 200' using standardized bottom gases of 18/45 and 15/55 with two decompression gases (Nitrox 50% and 100% oxygen).​  New material includes the nuances of using hypoxic trimix, gas management and failures management of multiple decompression gases, and the in-water management of multiple decompression bottles​.


Tech 2 is taught in double cylinders with backgas of Nitrox 32% (for skills dives) and standard gas helium mixes of 18/45 and 15/55, with two decompression bottles of Nitrox 50% and 100% O2 for accelerated "on the fly" decompression.  


The diver will be entering mandatory decompression obligations in this class.  This allows the diver to conduct his own technical dives in the 200’ range with two decompression bottles (a stage bottle endorsement is available with this class). ​


​Tech 2 expands on the Tech 1 skills, and is designed to cultivate, integrate and test these skills, which are essential for safe technical diving, . ​


Tech 2 is taught in double cylinders with two deco bottles and focuses on ascents and mid-water skills, ultimately testing the divers with their ability to identify, manage and resolve failures during the ascent and critical gas switch, which are essential for safe technical diving.


This is a critical skills class. Failures will be introduced by the instructor to facilitate problem identification and resolution and building capacity and bandwidth for more progressively challenging diving.

WHY TECH 2?

This course is for Tech 1 divers who wish to increase their operating range to deeper depths, have reached the limits of their Tech 1 training and experience and want a new challenge or wish to add a second deco gas to their skill level for projects with Tech 1 level dives with extended exposures .


Increased depths bring increased operational logistics.  Tech 2 trains the diver to explore those deeper depths using double cylinders of hypoxic trimix and two deco bottles (maximum decompression 60 minutes).

SKILLS & DRY RUNS

Tech 2 is taught in double cylinders with backgas of 18/45 or 15/55 with two decompression bottles of Nitrox 50% and 100% O2 for accelerated "on the fly" decompression (maximum decompression obligation of 60 minutes). 


Tech 2 consists of at least 6 dives: 4 practice & critical skills (failures) dives and 2 experience dives to up to 200'.


This course is an  extended decompression class, divers in this depth range must be aware they will be entering into mandatory extended decompression commitments and should be prepared to do accelerated decompression on the fly after extended bottom times at a max depth of 200' on the experience dives.  Decompression will not exceed 60 minutes.


Upon successful completion of Tech 2, the diver is fully qualified to conduct technical dives to 2000' using standard helium gases of 18/45 or 15/55 with 2 decompression gases of Nitrox 50% or 100% oxygen, with the option of a bottom stage (if endorsed).  

ACADEMIC TOPICS & VIDEO REVIEW

Extensive academic discussions and experience dives will focus on selecting the proper backgas, with heavy emphasis on decompression gas management and multiple decompression bottle management.


This class is designed to provide a deeper knowledge of Nitrox/Helitrox, oxygen decompression including an understanding of the history and practice of decompression, physics, physiology,  tables, minimum deco (within N.D.L.), ratio deco on the fly and other operational considerations including technical gas planning and management (minimum gas, or "Rock Bottom") and contingency procedures. 


Our diving days end with video review of the day's dives.  All FKD classes are video'd for educational and review purposes only.  We believe it is invaluable for students to visually focus on their individual in-water skills, situational awareness, communication and team diving.  Learning to self evaluate is an important aspect of the class.  


Our focus is the complete dedication to your diving skills, knowledge & in water practic
