Once an instructor has completed a course, better first start teaching to gain more experience and to find your own way of teaching.

Don’t go on with the so-called Go-Pro courses here on Koh Tao, where they prepare you in no time to become a staff instructor, without having taught one diving course yourself.

As a result, you simply miss the necessary ‘dive-hard’ experience of independently providing diving training under all kinds of circumstances.

However, over time, more serious instructors seek a little more variety, by going on to follow up on instructor training.

This is often out of pure interest, but after further training as a specialty instructor rating also gives more chance of work opportunities and gives more variety in your work!

Impian Divers can offer you all the necessary follow-up courses for instructors.  The1st  step is Specialty Instructor.
