On my most recent field program in Greece, we surveyed for ancient shipwrecks in the Greek National Marine Park of Alonessos and the Northern Sporades. My Greek colleagues heard a local rumor of an ancient wreck off a certain island in the archipelago, and before I arrived with the Pegasus thrusters they had searched for two days in very steep underwater terrain. No joy.
When I arrived, we headed back out to the island. Two of my Greek colleagues strapped on the thrusters - their first use of them. Using the Thrusters they covered more ground than they had in the previous two full diving days. In about 20 minutes they discovered a 1,000 year-old shipwreck. Proof positive of Pegasus Thruster's utility for our kind of work.
