Hi.

I'm booked on a Trimix course the first week of June with Jarrod
Jablonksi.
Unfortunately, the other student who was doing the course with me has
had
to cancel.

So there is at least one space,  possibly two, on the course (JJ said =
he
will
take up to three students). If anyone is interested in filling the
vacant slot,
please email JJ at JJCAVE@AO*.CO*.

				Trimix Course

This 4-5 day course is designed for the experienced deep diver who
wishes
to safely explore greater depths. This course maintains small numbers
and
is especially structured around the participants. Discussions include a
working
knowledge of trimix (oxygen-helium-nitrogen) advanced gas physiology,
planning
and operations, mix selection, staging, accelerated decompression
techniques,
mixed gas tables, gas blending, and gas analysis. Equipment =
requirements
are=20
similar to full cave with the addition of one oxygen clean tank and
regulator, and
one nitrox tank and regulator. The Trimix course may vary depending on
the divers'
experience. Divers that have not received full cave certification from
me may be
required to engage in additional training possibly impacting the course
fee. A diving
resume is required prior to participation in the Trimix course.

Prerequisites: Full Cave Diver, Eanx Cave, or Technical Nitrox , =
minimum
of 200
logged dives. A diving resume is required prior to acceptance into the
Trimix Diver
course. This course may be combined with some of the required
prerequisites.



Course Content: Lecture topics and actual dives will focus on a variety
of areas:

	Personal limitations
	Navigation
	Advanced decompression procedures
	Crisis management
	Deep diving (maximum depth 300 feet)
	Operational planning
	Bottle management
	Extended Penetration
	Gas management
	Equipment configuration
	Gas blending
	Oxygen cleaning


Training is conducted within a minimum of 3 days. Typical course format
is four-five
days. The first two days of training are tailored precisely to the
students experience
and may include a day of shallow cave diving. The following days are
typically conducted
at Eagle's Nest and Dipolder. Bottom times typically run between 20 and
30 minutes
and will include roughly 60-90 minutes of decompression. All advanced
training is
tailored to the students needs. Combination courses or advanced
penetration courses
are available. Weekday training is strongly recommended.



Equipment Requirements:

Personal diving equipment with the following additions: double tanks
with manifold,
two first stages each supplying one second stage (one of which must =
have
a seven
foot hose), a pressure gauge, 25 watt light with single burn time of at
least 60
minutes (120 minutes / day), two reserve lights, harness and wings type
buoyancy compensator, decompression tables, safety reel, suitable
thermal protection
(72=BAF / 21=BAC), two timing devices (preferably wrist mounted). One =
timer
should
have a stop watch function.


Fees:

approximately $600 (depending on course structure and student
experience)
                              Additional  Costs:
                              Air fills, rental equipment,
transportation, lodging, food, and
                              certification cards.
                              Estimated admission fees - $50
                              Estimated air fill fees - $50
                              Estimated gas fees - $175 (Oxygen @ $0.15
/ ft3, Helium @
                                           $0.30 / ft3)
