NORTH FALMOUTH, Mass.--(BUSINESS WIRE)--March 18, 2004

BENTHOS, INC. (NASDAQ: BTHS) announced today that it has been awarded a contract to deliver one of its new C3D(TM) 3-Dimensional Side Scan Sonar systems to the National Institute of Ocean Technology of India.

The C3D(TM) system combines high resolution imagery and wide swath bathymetry for unprecedented bottom mapping, image interpretation, and a 3-dimensional look at the seafloor. The C3D system represents the latest in sonar imaging with patented technology that incorporates a multi-array transducer and its capability of solving for multiple angles-of-arrival.

SARA CAATI (Small Aperture Range Angle and Computed Angle of Arrival Transient Imaging) is a patented technique licensed to Benthos by Simon Fraser University. It is a method for estimating the backscatter arrival spectrum. SARA CAATI uses an angle-of-arrival estimation similar to interferometry. However, unlike interferometry, the C3D system solves the problem of concurrent arrivals from multiple angles. We believe that the C3D system is the best available solution for combining side scan imagery and bathymetric data.

Developed over the past two years, the C3D system can save time and money for surveyors because only one survey is necessary for both imagery and bathymetry. The system is ideal for fisheries habitat mapping, port and harbor clearance, coastal studies, deep ocean mapping, cable route surveys, and mine countermeasures.

Benthos, Inc., through its Undersea Systems Division, designs, manufactures, sells and services a variety of oceanographic products for underwater tasks; and through its TapTone Package Inspection Systems Division makes systems for testing consumer packages made of glass, metal or plastic. The common stock of the Company is traded on the Nasdaq SmallCap market under the symbol BTHS. For more information, Benthos can be found on the Internet at www.benthos.com.
