redundant scuba unit ( three hundred an
seventy (370) liter (3L) minimum).
2 - A submersible pressure gauge.
3 - Depth gauge and automatic bottom
timer and/or dive computer.
4 - Buoyancy Compensator with power
inflator.
5 - Exposure suit adequate for the open

The TDI Advanced Nitrox Course qualifies
divers to use enriched air nitrox from
EAN 21 through EAN 100 to a depth of 40
metres/130 feet during dives hat do not
require staged decompression. Often
taught in conjunction with the TDI
Decompression Procedures course, this
can be considered the foundation of your
technical diving career. Advanced
Nitrox is also a great course for those
wanting to extend their bottom times in
shallower depths such as scientific
diver, and a must for SCR or CCR divers.
The course cover topics like:
1 - Equipment requirements.
2 - Dive planning.
3 - Oxygen tracking.
4 - Blending methods.
You will use the TDI Advanced Nitrox
Diving manual for your course, which
explains in an easy to understand
practical manner the complex information
that Advanced Nitrox divers need to
know.

The TDI Inspiration and Evolution
(certification depends on
unit/electronics used) is your first
step into closed circuit rebreather
diving and your first truly quiet diving
experience. Using the latest in
technology CCR’s maximize your gas
supply of Nitrox and provide the optimum
breathing gas for any depth by
maintaining a constant partial pressure
of oxygen (PPO2). During the dives
(minimum of six) your TDI Instructor
will teach you all the necessary skills
to conduct CCR dives to a maximum depth
of 40 m / 130 feet.
The skills include:
1 - Setup and maintenance of the unit.
2 - Loop volume management.
3 - Calibration of electronics.
4 - Emergency procedures.
5 - Buoyancy control.
6 - CNS tracking.
The TDI Inspiration/Evolution manual
provides comprehensive information about
the units and how they operate during a
dive. Also available is the
Inspiration/Evolution build-up check
list that can be adhered to the unit
case for easy reference.
