The Samyung SES2000 echo sounder is a breakthrough over the conventional paper eating sounders; there are no consumable items. The purpose of the echo sounder is to provide safe navigation by detecting the clearance below the ship (particularly in shallow waters) as required on the SOLAS Convention ships by the new IMO standards.
The basic system consists of a display unit, a junction box, and a transducer.
The 10,4″ high-brightness TFT color LCD display offers an easy-to-read depth sounding in various modes, permitting optimum representation with respect to the environment.
Detection range is automatically varied but there is manual override to select the required scale. The displayed record is visible for 15 min on any range and an instantaneous sounding is directly shown in large numerals in addition to the graphical display. Depths, associated time, and position are stored for 12 h in memory. The data can be played back at any time.
Visual and audible alarms are generated when the water depth below transducer is shallower than a user-preset depth. When the seabed is lost because of the lowered detection or out of range setting, the alarm comes on. The receiver sensitivity is automatically controlled with the tracking depth; manual override is possible to improve the detection and to reduce the surface clutter.
