I am an advance diver (Rescue diver), and considering going for Dive Master, but not as a professional. I mainly dive in the tropics, and I am looking for a low profile, simple BC that has integrated weights, and some place to hookup my SpairAir. I am looking at DiveRite Transpack, SCUBAPRO Nighthawk, or Zeagle; Scout, Escape or Stiletto. Will appreciate any input on pros & cons.
