I completed my Trimx training with Scot Byars in Spring Hill, FL. I dove in a cave to a depth of 270 feet. I am certified to dive to a depth of 330 feet.
The previous certification of Normoxic Trimix allowed me to dive to 200 feet. There are many wrecks basically untouched at between 180 and 240 feet.
I also completed my Advance Cave with Staging. This was a skill course that took me three trips to Florida, and about 12 dives to complete. This advances my ability to control extra tanks and helped me get my equipment set to the point of familiarity. The two classes complement each other because of the handling of multiple tanks (stages)
Like most classes you sometimes think you can finish them in a specific time. Trimix is 4 dives and lots of math. Which I completed in the minimum. Staging is up to the instructor. I am glad I had to work for staging. It without a doubt helped me in the skills I need to develop to become an elite diver.
