Every qualification in life is valued on how difficult it is to get. By the time a Doctor actually practices they have 8 to 10 years of training, so they can command a high remuneration.
By contrast you can become a diving instructor from zero in less than 2 months of training time. So it is nothing special. Really it is just semi skilled manual labour.
If you actually want to make money from instruction you need to find an angle. Own the dive shop. Train difficult things like trimix. Become a total watersport expert and work a cruise liner. Etc.
Being able to teach scuba, on it's own, is a simple skill that attracts no financial premium. In fact because so many young people are prepared to do it for the life style, it attracts a financial penalty.
Research this fully before you do it.
It actually takes 6 months to go from Zero to Instructor, and even then it is a pefomance based process, if you meet the Industry benchmark then you can become an Instructor through a trained and audited process, of course the medical field is far more comprehensive and sacraficing.
Our Instructors are paid based solely on commission of the students they train as in resorts we do not retail a high portion of equipment, most of our divers (unless in training) come fully equipped. However our average Instructor earnings tend to average $700 in low season to $2500 in high season, most of our Instructors are able to work 6 months of a good season and leave/move on with a good savings, plus have enjoyed great diving, an amazing lifestyle and gained good experince.
As BrucieBabe says if you are in the industry for the long term then you need to gain additional credentials to make a more attractive income however the 'Open Water Scuba Instructor' rating is your entry level into the dive industry and will let you decide where you next want to move, and if the industry of diving apeals to you then you can do extremely well. I never planned to become a dive centre manager or Instructor trainer, it was just a natural progession from something I enjoyed into a sport I loved.
Even though the majority of Instructors make a minimal wage they often will say that when they wake up each day they do not go to work, but they live a lifestyle. I guess at the end of the day, when you lie on your death bed what will you look back on and wished you did more of???
A) Dive and have fun
B) Work and make $
For me, being a Scuba Instructor, still remains one of the best jobs in the world!!!
Remember that when your watch chimes 9am on a Monday morning and you guiding a group of divers over a coral reef!!!
Warm regards,
