If you are looking to exceed the depth limits of diving air and Nitrox, the TDI Trimix or PADI Trimix 65 course is a great way to achieve your goal! Trimix is a blend of oxygen, nitrogen, and helium which is used to perform technical dives up to 200ft/60m in the safest manner while reducing your levels of narcosis. We will talk about the advantages and physiological properties of helium as a breathing gas and evaluate how Trimix behaves during decompression. You will now start using multiple staged decompression tanks and will have to perform gas switches at depth to maximize the efficiency of decompression.

This course is made up of 4 decompression dives over 3 days with a minimum of 100 minutes total bottom time, of which you will perform two dives deeper than 130ft/40m. Although the TDI and PADI courses are similar, there are some differences in standards/prerequisites.

Before you start you may choose TDI or PADI for certification.

All  technical courses require a Medical Statement signed by a physician within the last 12 months & require the student to have DAN insurance or equivalent.
