Been trying to talk to my LDS about it, but every time I stop in, the boss is out on some errand.
What type of classroom, confined, or open water work is required and about how many days?
I currently have about 300 dives, AOW and rescue.
A lot of the DM course requirements include you assisting with actual courses. If a shop is not very busy, scheduling these courses in such a way that you can be included can take a while. Just something to keep in mind... and why Tursiops in Post #2 suggested that you might want to consider going elsewhere.
The requirements of the DM course typically take much much longer to complete than those of your other courses. AOW or Rescue can be done in a week, even one long weekend if you push it. But DM... plan on it being spread out over a few months.
