So… you have your new photo equipment. Cool... now what? Should we just jump in the water with it?

Jim Abernethy, owner and operator of Scuba Adventures, was the dive operator who showed all of the others that sharks are peaceful animals who want nothing to do with humans as a food source.

He spends most of his time with wild sharks during dives from his liveaboard ship, The Shear Water, at remote sites in the vicinity of the Bahamas, and is on land for only about 40 days a year.

A rebreather dive begins before you enter the water. You strap on the machine, put on your mask, or pinch your nose, and “pre-breathe” the unit for five minutes while monitoring the sensors and heads-up display (HUD) for any signs of trouble. It’s usually one of the last checklist items to complete before commencing the dive depending on the rebreather.

The month of November sees the return of the international dive industry trade convention, the DEMA Show, to Orlando, Florida, USA. In a peek-behind-the-scenes conversation with Tom Ingram, Executive Director of DEMA (Diving Equipment and Marketing Association), Rosemary Lunn’s interview reveals an engaged, enthusiastic diver who is passionate about our industry and the business of diving.
