GUE Tech 60

Course Outcomes

GUE’s Tech 60 course is designed for divers who want to explore the intermediate realm between Tech 1 and Tech 2. It trains them in the use of a bottom stage or second decompression cylinder which grants them more flexibility during multiple dives and/or longer bottom times. Additional outcomes include: gas planning during longer dives, bottle management, emergency management strategies and decompression considerations during longer bottom times.


Applicants for a Tech 60 course must:

  1. Submit a completed registration form, a medical history, and a liability release to GUE Headquarters.
  2. Be physically and mentally fit.
  3. Hold insurance that will cover diving emergencies such as hyperbaric treatment, e.g. DAN Master-level insurance or equivalent.
  4. Be a nonsmoker.
  5. Obtain a physician’s prior written authorization for the use of prescription drugs, except for birth control, or for any prior medical condition that may pose a risk while diving.
  6. Be a minimum of 18 years of age.
  7. Be a certified GUE Tech 1 Diver.
  8. Have a minimum of 25 logged technical dives beyond Tech 1 certification


Course Content


The Tech 60 course is normally conducted over four full days, and requires at least seven dives and a minimum 30 hours of instruction, encompassing classroom, land drills, and in-water work.

Tech 60 Specific Training Standards

  1. Student-to-instructor ratio is not to exceed 3:1 during any in-water training.
  2. Maximum depth 200 feet/60 meters.
  3. If conducted in a cave, trainees must be at least GUE Cave 2 certified divers; instructors must be active GUE Cave 2 instructors.
  4. Dives should not be planned to incur more than 45 minutes of decompression time as established by GUE’s DecoPlanner.
