Raytheon Marine Company has introduced a new commercial chartrecording echo sounder with performance features meeting and exceeding IMO depth indicator requirements for ships traveling in international waters.
The Raytheon RD-500 Echo Sounder records and prints depth in six ranges from zero to 10, 25, 50, 100, 500, and 1,000 feet, meters, or fathoms. Time and event marks can also be printed on the chart. Digital display of depth is provided by three-digit LCD on the front control panel. An audible depth alarm indicator, with buzzer reset, is presettable from one to 999 feet, meters, or fathoms, to warn of shallow conditions.
The chart, LCD, and front panel controls have adjustable backlighting for comfortable viewing, day or night. The dry, electrosensitive recording paper is 8 inches (204 mm) wide. Remote digital depth displays are available.
Noise cancellation circuitry rejects unwanted random signals by cross-correlation of previous returns.
Accuracy is ± 0.2 meters in the shallow ranges (0-100 meters), and ± 1 meter or 2';< of the indicated depth, whichever is greater, on the deep ranges.
Raytheon's RD-500 Echo Sounder has an 80-kHz transducer. It is also available without a transducer, for use on ships equipped with Raytheon's DSL-250 MKII and DSL- 450 MKII Doppler Speed Logs.
The IMO (International Maritime Organization) Amendments to SOLAS 74 (International Convention for Safety of Life at Sea) adopted in 1981, recommends that on international voyages, ships of 1,600 tons, constructed before May 25, 1980, and ships of 500 tons, constructed on or after May 25,1980, be fitted with chart-recording echo sounding equipment which meets certain performance standards. In addition to IMO requirements, the RD-500 meets 1982 British DOT Requirements for Marine Navigation Equipment.
Manufacturer's suggested list price for the RD-500 Echo Sounder, including 80-kHz transducer, is $3,995. Raytheon provides a oneyear limited parts warranty with one-year free service from any of its U.S. dealers and worldwide service network.
