It is well known that the Instructor makes
the class, and that he or she should have
far more experienced than diving with
students, with explorations efforts at top of
the list.

But shouldn't the Instructor have also
experience in other fields? He or she must
be a certified diver in different areas, for
example a tech Instructor will benefit from
personal cave training even will not teach
it. If a no tech and/or rb diver teaches cave
diving, his knowledge will be very limited in
what he can teach students at a high level.

However even experience divers find
difficult to decide the next step on their
diving career training

Normally divers choose the level of training
they wish to operate safely and maybe
even have done a bit already. Even they
may not be prepared properly for it.

Personally I tend to recognize experience
far more valuable than certificates, but a
diver with no training could be walking on
thin ice.

In the table below, I hope help you decide
what training should be next for you. Start
at right and move left from diving activity  
towards recommended training.    
Is important to sincerely reflect your diving
experience with the prep-requisites and
last limitations with your diving environment.

If you already have all the cards but are
new to DIR or wish to have a review I
recommend to apply for custom session to
any level.

I wish you great fun on your next training
session and lots of underwater adventures
Training Considerations :

Training in English, Spanish, Italian or French

Due to inconsistency on diver training applicant divers most secure approval prior attending training.

Tech 2-3 certifications by no cave diver Instructors and/or
Cave 2-3 certifications by no tech/rb divers Instructors will not be recognized,
unless extra days to secure shortcomings are planned

Experience Trimix Divers and Wreck divers or Instructors could apply for a Cave 2 class,
only if accepting to be certified to level achieved in training time frame.

Notice we don't do single deco tech diving beyond Hiperoxic trimix,
choose no to push the depth limits on ocean dives,
prefer to do long range dives only in cave like environments,
and always use scooters on deco dives.

We discourage the use of thirds in 2 people teams on the overhead environment,
specially with half full tanks at cave 1/ Intro to cave level.
We recommend to cave dive always with a stage bottle and
never swim with more than 2 stages,
or scooter with more than 3-4 bottles and/or 2-3 scooters.

Equipment Considerations :                                     Equipment Pictures Page

Diaphragm regulators are prefer on back gas and back gas stage bottles,
piston regulators desired on deco and safety bottles.

Wings with bungee's styles are not accepted.
Halcyon inflator must be replace for reliable ones.

Only Stainless Steel backplate's are acceptable.
Drop weights are prefer to Weight belts.

Tanks used are 12x12, 18x18 and 11Lt / al80 stage bottles,
duct tape labelling is not accepted.

Minimum burn time on P lights is 3hr, 180 minutes.
10 watt hid is not accepted and NIMH discouraged

Dry gloves are discouraged above 8°C / 45°F

Argon is mandatory on deco dives,
tank mounted is highly recommended and
backplate mount is not accepted past Cave 1 level.

Gavins PVC tails max depth is 80mt,
Aluminium or HDPE is 100mt

CCR rb are not allowed on OC classes
Cavern diving within the sunlight
