Tec 50 Program                                TecRec Logo

Tec 50 Course

The Tec 50 course completes your training as an entry-level tec diver, taking you well past the limits of recreational diving.  This is essentially the final course that student tec divers will take in preparation for continuing on to full tri-mix certification if they so desire.  Students will become proficient at handling multiple (two) deco/stage bottles, varying gas mixes up to 100% oxygen for accelerated decompression, and making blue water ascents to the surface maintaining controlled decompression stops.

By the end of the Tech 50 program a student technical diver will be fully prepared to conduct decompression dives, handle predictable emergency situations, and have the skills necessary to complete dives to 165 feet for extended bottom times, safely and confidently.


What You'll Learn

During the Tec 50 course, you

  • Make actual decompression dives as deep as 50 meters/165 feet
  • Learn to carry and deploy two deco/stage bottles with up to two different decompression mixes
  • Practice extended decompression stops making multiple gas switches
  • Use enriched air nitrox and/or oxygen for accelerated decompression
  • Become proficient at handling multiple potential failure paths during a decompression dive
  • Use desk top decompression software to create custom dive tables and plan your dives
  • Qualify to make technical decompression dives independently 

The Learning Materials You'll Need

You'll use the Tec Deep Diver Crew-Pak, which introduces you to

  • tec diving lingo
  • emergency procedures
  • standard technical diving equipment
  • decompression and stage cylinder handling
  • gas planning
  • complex dive planning
  • dive team procedures and methodologies

The pak includes a manual, dive planning checklist and dive planning slate. The optional Equipment Set-up and Key Skills video on DVD is a great tool to help you practice at home in between your tec diving adventures.
