Many people are confused about these terms and their official use. Here is an explanation of these terms as PADI uses them and the reality of the situation.Ok this was asked about 75 pages ago...........What ARE there actual certifications/qualifications? If anyone knows feel free to let us know. I have seen MANY people refer to the other 2 as DM when in reality I think Gabi is merely a diveguide with no official designate as a "DM".....I would imagine OPAL is a certified instructor and had the correct level of expertise and training required to run a shop.
Dive Guide: This is not an official PADI term, nor do I think any agency uses it. Anyone can be a dive guide, but to do it professionally one should have professional liability insurance, and someone who does not have a professional certification cannot get liability insurance. There are tons of professionals with proper certification looking for work, and I cannot imagine a shop of this nature using someone who was not professionally certified. It would be a tremendous and completely unnecessary liability risk for a shop to use an uninsured dive guide.
Divemaster: This is the lowest level professional certification. A divemaster is allowed to lead dives and assist in instruction in a very minor role--mostly watching to make sure no one drowns while the instructor is working with individual students. A DM can get and MUST MAINTAIN professional liability insurance covering him or her for accidents that occur while leading dives or assisting in instruction. Since a divemaster is very limited in what can be done, it is common for dive operations to require a higher level of certification for employees so that they can be more versatile.
Assistant Instructor:An assistant instructor is essentially a DM with additional training in instruction who is allowed to do more work while assisting an instructor in class. Not many people have this level of certification because it is only beneficial in unusual situations.
OWSI:An Open Water Scuba Instructor can teach any recreational class and can also lead dives. I would guess that the vast majority of people who work as DMs in resorts are actually at least at this level. Operators prefer this because these people have the ability to teach a class as needed.
MSDT:A Master Scuba Diver Trainer is an OWSI who has certified a number of divers and who has completed the requirements to teach at least 5 specialty classes. Once again, because these people have the ability to teach specialty classes as needed, many of the people who are leading dives under the title of DM in resort areas actually have this much higher level of certification.
In short, I would be stunned if Opal and Gabi were not at the very least officially DMs, and I would not be surprised in the slightest to learn that both are MSDTs.
