Fish sounder JMC V-3002

Dual Frequency (50/200 kHz) commercial fish finder based on 10.4-inch VGA daylight-viewing TFT LCD.

Echogram is displayed using full VGA graphic pixel specifications for superb echo resolution.
Transmits 1 kW RMS of power at both 50 kHz and 200 kHz, with automatic selection of appropriate transmit pulse and sounding rate for depth range in use.
Wide screen can be split vertically or horizontally in two, with one half showing high frequency echogram and the other half, low frequency echogram, or with one half showing normal echogram and the other half, expanded echogram.
Trawl display mode allows separate depth range settings across split-screen high and low frequency echogram displays.
