The Shark POD and footplate were fixed about 90cm apart to a buoy and submersed in the water with the POD just below the surface. The switch for the unit was accessible from the boat. It took several hours for a shark to come close enough, but finally one swam under the boat a couple of times. The shark returned swimming across the back of the boat. As it reached the port side of the boat it rolled on to its side readying for an attack to the motor. As the shark drew level with the prop I activated the Shark POD, which was submersed on the starboard side about 2 metres away from the outboard leg. The shark immediately shuddered and froze. After several seconds it veered sharply away from the boat and disappeared.
The cost of the Shark POD was certainly vindicated. Simply put, the Shark POD is as much a part of our dive equipment as the air tank.
