EdgeTech Side Scan Sonar System Used in Locating Shipwreck Yielding $500 Million Treasure.

An EdgeTech 4200-MP Side Scan Sonar System, owned and operated by Odyssey Marine Exploration, was used in locating a shipwreck code named the “Black Swan” which yielded over 500,000 silver and gold coins that have been estimated to be worth somewhere around $500 million. This was the same system used by Odyssey in 2003 to help locate the SS Republic, which produced more than $75 million worth of coins.

The 4200-MP used for the survey was the dual simultaneous 100/400 kHz version. The 4200-MP utilizes digital CHIRP technology which provides higher resolution imagery than conventional analog and digital systems as well as extended range; an important factor when trying to locate a shipwreck. The 4200-MP has a low frequency range that is 30% greater than conventional systems at the same frequency and a high frequency range that is 50% greater.

The EdgeTech 4200-MP is dual mode system (High Definition Mode & High Speed Mode) available with either 100/400 kHz or 300/600 kHz dual simultaneous frequencies. Additionally the system is available with a choice of a rack mount or portable topside processor as well as a stainless steel or lightweight aluminum towfish. These options give the customer the ability to configure the system to best suit his needs.

The 4200-MP can also be installed on an AUV or ROV and comes available with a multitude of additional optional sensors.
