Trimix Diver
As
your motivation to explore progresses you will find that you may want
to go deeper to dive that wreck that is part of history or that cave
system
that you have read so much about. One of the major limiting factors of
going deeper is narcosis; TDI’s Trimix Diver course shows
how
to minimize the effects of narcosis by adding helium to offset the
nitrogen in your breathing gas. While taking the Trimix Diver course
your
TDI Instructor will teach you how to plan and execute
dives utilizing as little as 18 percent oxygen and diving to maximum
depth of 60 m/200
feet with a blend of helium appropriate
for the planned depth. The course covers topics and skills like: (1)
Dive team planning, (2) Gas
matching, (3) Cylinder labeling, (4) Surface marker deployment, (5) Equipment configuration, (6) Thermal protection options
