New narcosis test report and responsible behaviors.

  Laurent, diving instructor (BEES1), 37 years old Half Marathoner, very active in diving since May.

Has chained several N3 sessions, level 4, jury monitoring, baptisms.

Carried out the narcosis test “for fun” at 34 meters water 24 ° C very good visibility no current.

Test results:

- Labyrinth tests: 40% increase compared to the surface (3 meters)

- Pointing tests: a slight delay in pointing no time difference.

–Multiplication tests: 2 errors and 50% more time (VERY IMPORTANT DANGER) according to our scale.

- Numbers ordination tests: carried out with an increase of 50% than on the surface, but with a forgotten number

Personal interpretation of the results: the danger is very important, both for the instructor himself and for his pupils.

This report clearly shows that fatigue, coupled with an "average" depth (for a monitor) generates significant risks, these risks are easily detectable by the test.

What would have happened with an N2, in very bad diving conditions?

ATTITUDE hyper-responsible for the director of the structure : the monitor was stopped a week to rest ...

The instructor himself had an awareness ... (very rare)
