Main Features

  • Full color echogram across 10.4-inch daylight-viewing TFT LCD screen with 3 selectable background colors. Echoes are shown in up to 7 user-definable colors. Up to 4 echo dynamic ranges are also selectable depending on bottom conditions.

  • Dual frequency operation covering 5 to 1000 meters of depth in 8 range steps manually or automatically, with a single keypress selecting high frequency (200, 135 or 100
    kHz) or low frequency (50 kHz). Depth readout in fathoms or feet is also available.

  • 1kW (max.) transmit output with power level automatically adjusted to suit the range selected. Manual override is also possible in special situations where more power is needed for shallow water soundings.

  • Shows LAT/LON and water temperature data in addition to sounding data and associated date/time when appropriate optional sensors are plugged in. These types of data are automatically output via RS-232C and RS-422 ports for use by ECDIS, VDR and other onboard electronics.

  • Up to 24 hours of sounding and other data are automatically stored in non-volatile (flash) memory protected from power outage/shutoff or system reset

    Stored data can be displayed graphically as well as digitally in a special data history window accessible with a single keypress, and can be uploaded to a PC for off-line processing and analysis.

  • Agraphics printer can be plugged into a devoted rear panel connector to print out a monochrome hard copy of the current echogram.

  • Echogram feed rate can be changed in 3 steps for extended display period across the screen without affecting the sounding rate.

  • An extensive alarm function audibly and visually warns the navigator against decreasing depth, missing or weakening bottom echo, power supply voltage drop and power outage.

  • Both AC and DC power supplies are built in, with automatic switchover to DC power source in the event of AC power line failure.

  • Complies with IMO Resolution MSC.74(69) and Wheel Mark regulations
