The Technical Tri-Mix program expands on the applications and procedures of the TSD course by introducing the use of Helium (minimum of 16%). It is an ideal training program for those looking to benefit from Helium use but have no desire to go to extreme depths. The operational depth limit for this program is 50 msw. The TTM program includes 4 - 6 hours of lecture and 4+ open water training dives. Minimum run time is 180 minutes.
Prerequisite: ANDI TSD. Other pre-requisites may apply.
