Fish sounder JMC V-6202 / V-8202

Dual frequency (50/200 kHz) 6-inch TFT-LCD QVGA echo sounder housed in an electrostatically shielded sturdy, high-impact plastic cabinet.

Model V-6202 - 6,0 inch display, V-8202 - 6,5 inch display.
Fully automatic mode of operation allows automatic selection of depth ranges and setting of receiver gain/STC levels for optimal display of bottom and fish echoes.
Manual override is also available to operate the equipment with user-selected parameters.
Advanced setting mode allows separate settings of frequency, range, gain, STC, feed rate, echo/background colors, dynamic range, and other parameters across split screen displays, making it possible to customize the left-hand screen to suit specific applications, while monitoring overall underwater activities beneath the vessel across the right-hand screen.
