Real good advice so far, but let me reflect on your
exact questions. I hope I am not misinterpreting...
Colorado Mermaid:
I might have a chance to go do a one-on-one internship at a small shop in Costa Rica, or do the typical mass training in Roatan.
I think you can get one-on-one or "mass training" in either location. In the US, you will find the major IDC's have "start dates" so you will be in the mass training, beginning with others all at the same time. In the situations you refer to, you would likely see a rotating process where you show up to start while others are at various stages.
Do not go to DM school to
learn about diving. You can do that, but I believe it to be a waste of time. To learn about diving, you have to dive. True enough, if you act as slave labor for a dive operation, it will not only give you BT, but it will help attune your focus to the minor details of each dive and various divers. That is one great selling point of the protracted version of the process.
On the other hand, if you go to any one of the US based larger IDC's, if you are an experienced diver, you can walk through the DM course in just short of two weeks. To help you understand the process, know that you would be smart to immediately go after the AI and OWSI course as the book learning is exactly the same. Why memorize all that stuff twice? The only difference is that your demonstration and presentation skills are held to a higher standard.
Does getting certified in Roatan help or hinder your chances ....see how it would be viewed as a factory where they just push out anyone ....No one will know the small shop in CR, so they won't know what kind of training I received, but it would be more concentrated attention
It is roughly equivelant to having a college degree (in 2007). It's a check-off box on the application for employment form.
(and more challenging diving - good and bad, for me).
The challenge of the diving is irrelevant. As you become a DM, there should be no big hurdle for you to overcome. True- you may not have seen this or that situation, but if you are ready for DM, you have developed the ability to carefuly listen to a dive breifing and understand how the particular boat will be rigged, the entry, the plan, the conditions, the exit. Unlike most divers who just hear "
Backroll blahblah Seahorse blahblah 1200 psi blahblah".
You will already have the ability to listen, decode and understand. There should be nothing you can't deal with after breifing.
I guess, in short, what do the people who hire you look for in a resume?
To hire you as a DM? Largely they look for a detactable pulse and the body strength that will allow you to carry tanks as necessary. They look for a good presentation- how you speak and your contact skills. They look at your boat handling skills, also your marine awareness- you are working in an industrial environment- they don't want you bleeding on any customers.
Also, do you find that women have an easier or more difficult time getting hired? I have been to a few dive job sites, and "women preferred" seems to be a common thing, but I am wondering why? And is it true in practice?
Welcome to the real world. Look at the statistics. Tall, good looking people make more money in the business world. Females in bathing suits are attractive to business.
Women sometimes often do not last long in dive-ops for any one of several reasons. If they can't carry the physical load...all their boat's tanks; if they hook-up with any other employee, any island DM, Instructor, or tourist; start sloughing off on the physical aspects of the job allowing "helpful" panting associates to do the heavy lifting; teasing; not teasing; drinking more than one; and the list goes on and on. It's still a man's world in vacation diving, and sorry to say, this is amplified by the fact that you have crossed into a country with a macho based national mentality more often than not. Male DM's wives and girlfriends will hate you, the male DM's will use that to their advantage. Female DM's will not be overly helpful. It's just the real world in bathing suits. You are likely to get tipped less. Female guests will likely not want you too close to their man, either.
Not an easy road.
But I highly recommend that you give it a shot. If not now, when?
