gcbryan:My main point is that many if not most divers who become DM's aren't really interested in diving but are interested in teaching or in collecting cards. If you are really into diving why would you want to be a DM? You will spend nights in a pool and most weekends in 30 feet of water checking OW students out. You will not have time to dive. Most DM's I have met silt up the environment that they are in, have lights hanging and dragging all over the place, don't know many local dive sites unless it is a checkout site or unless they are following someone else.
Many are impressed with themselves only because they feel they are experienced but only in comparison to those they hang out with (as yet uncertified OW students).
Go on any boat dive (outside warm water vacation spots) and the worst divers on the boat will be those that are also DM's.
Hmm, most DM's I've dove with were very good divers. I don't think you can paint with such a wide brush. I've seem more good DM's then bad.
DM is also a very broad term. A guy working in Coz as a DM (they are generally instructors) will have 1000's of dives, and will be exactly the guy you want leading your dives. They sip air, dive like fish, and know the sites like their backyard. I've found the same to holds true in FL at least on the boats on the east coast N. of the Keys where drift diving is the norm so you actually have a DM lead the dive.
