The system was tested early this month at sea near Palm Beach, Florida, where movements of 300-pound shark were tracked at distances of up to one and a quarter miles. The instrument, 10 ½ inches long, 2 ½ inches in diameter and weighing a little over one pound was attached to the shark behind its dorsal fin. The shark was released and tracked by a small boat carrying special range and direction finding equipment.
