I just tooke GUE fundie, and we went through what is where and because most of us in the class was not DIR, instructors also went through the why. Here is what I get from the class:
1. light on goodman handle on left hand. Because right hand is needed to donate the primary in OOA situation. If light is on right hand, the receiver may get punched on the face by the light head.
2. depth gauge and timer on right wrist. Because left hand is needed to vent wing and drysuit. While venting, once can continously monitor depth and time (especially ascent time). If you have a console, on say 24" HP hose, the console can only be hold by left hand. How would you vent while monitoring the gauge. Now let's say the HP hose is long enough to be hold by right hand. Venting with left hand while light is still on left hand will generate a very eratic movement of light beam. Eratic light beam means OOA. In the case where gauge is on right wrist, the diver should palm the light with right hand while keeping the beam stable, use left hand for venting.
3. compass on left wrist.
#1 and #2 are pretty good argument to me for lift hand light, right wrist gauge. #3 isn't as strong, but I don't find a reason to object it either.
