Please keep in mind that the original poster is currently listed as a NAUI Master Scuba Diver.
First of all, not all Master Scuba Diver certifications are created equal. SSI and PADI may hand these out like candy but some organizations actually require real work to be done to get this certification.
With respects to NAUI, the Master Diver course should teach a thorough understanding of dive equipment, physics, physiology, decompression theory, dive environment and other topics. The Divemaster course builds on to that base by adding information and skills that you would need in order to be able to supervise other divers. Very little diving knowledge is imparted during the Divemaster class since the diver should already know that information before taking the Divemaster class. The Divemaster class is more about working with people than about diving. At least it should be.
