Reductionism in Diving

For most divers, the more streamlined we are the better. Gone are the days of lugging around bulky, unwieldy, impractical survival equipment and oversized dive gadgets. We live in an era of all-in-one imaginations, and the sport of diving is certainly no exception. Case in point? The Mares All In One Dive Marker. Not only is it the life saving safety sausage we all know and love, but it has a compartment for stowing and attaching a reel and line for underwater deployment! How cool is that?

What do you think? Are there “old school” gadgets of yours that will stand the test of time in diving?
