Echosounders Japan Marina Company (JMC)

Black Box Echo Sounder JMC BV-6100

• Designed to add full function echo sounder performance to your C-MAP Track Plotters NP-20MAX, NP-30MR, Super Pilot MAX.
• Split screen display of C-MAP chart and echogram or full screen display of either image
• Displays echoes in up to 16 shades of colors for a detailed analysis of fish echoes, seabed or thermoclines. The color scheme can be changed for both echo display and background to suit the user’s preference or the ambient lighting condition.
• Supports a wide range of AIRMAR® 50 kHz and 200 kHz transducers and automatically selects appropriate transmit power level and frequency to obtain best performance from the transducer in use.
• Dual frequency echogram display across split screen with an appropriate 50/200 kHz AIRMAR® transducer plugged in.
• Five presets of operating modes are selectable to instantly set optimized parameters, such as gain, noise level and STC settings, for the current operating mode.
• A-scope is built in for instant assessment of echo size and strength without having to wait for echogram to scroll for a full graphic presentation.
• White Line allows bottom-feeding fish to be clearly separated from the bottom contour, and also helps examine the hardness of the seabed.
• Zooming function allows 2X/4X expanded echogram across the left half screen while showing normal size echogram on the right half screen.
• Adjustable velocity standard to compensate depth reading for water temperature and/or salinity.
• A total of six types of alarms can be separately triggered to alert the user to preset high/low depth limits, fish detection, upper/lower water temperature limits and temperature variation rate limit, depending on the transducer and thermistor sensor connected.
• Depth, speed, trip and water temperature data are available in NMEA-0183 format.

Specification:

Dual frequency color fishfinder JMC V-3006

• Full VGA graphic display of echogram in up to 7 analog RGB colors.
• 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.
• Vertical or horizontal screen splitting for dual frequency operation or full screen display of either frequency echogram.
• Independent depth range setting on each frequency in dual frequency operation.
• A scope display for instant assessment of fish size regardless of range or feed rate in use.
• Bottom-locked or pelagic expansion (zooming).
• White-line function helps in finding bottom-feeding fish by blanking bottom echo.
• Echo dynamic range selection optimizes bottom and fish echo color arrangement under various bottom conditions without changing receiver gain/TVG settings.
• Water temperature function is built in as standard, displaying temperature variation both digitally and graphically over echogram display.
• Optional GPS sensor to display position coordinates, heading and speed.

Specification:

Specification:

JMC V-6202 / V-8202 Dual frequency fishfinder

• Dual frequency 6-inch TFT LCD (V-6202) and 8-inch TFT LCD (V-8202), vertical display orientation
• Fully automatic mode of operation: range selection, gain/STC settings
• Customizable separate settings of frequency, range, gain, colors, feed rate and other parameters across split screen displays
• High sounding rate mode at 2X feed and normal sounding rate at normal feed across split screen
• Permanent or temporary storage of up to 10 pages of echogram screen
• Bottom-locked expansion or pelagic expansion across half screen
• A-scope display for instant detection of fish and assessment of its size
• Password-protection prevents unauthorized access or deters theft.
• Graphic guidance for returning to present position with optional GPS sensor connected

Specification:

JMC V-8100 High Power Dual Frequency Professional Fish Finding System

• Three-unit configuration, consisting of a control unit, a transceiver & power supply unit (black box), and an optional 15″ TFT LCD monitor or a user-purchased display unit, providing flexibility in choosing the installation site
• Just plugging in a PC monitor to the black box completes a sophisticated high power dual-frequency professional fish finding system. Housed in a marine sturdy cabinet, the optional daylight-viewing LCD monitor can be oriented horizontally or vertically for a prolonged echogram presentation or a high-resolution display.
• A total of 7 user-customizable depth ranges are selectable, enabling the user to set the desired maximum range limit for each range.
• Two transducers are selectable from a wide range of frequencies (from 20 to 200 kHz in 13 steps). Specify the desired frequency pair when ordering.
• The transmit power level ranges from 300W to 5 kW RMS depending on the transducers in use, each with 4-step power reduction.
• The display modes include a full-screen single-frequency mode, a dual-frequency split-screen mode and a screen memory recall mode. A nav. data page is also available with GPS data supplied externally.
• Double, triple or quadruple image feed rate is selectable for fast review of echo history in addition to a total of 9 regular rates, some with a display of time-compressed image of earlier soundings for extended echo history display.
• A total of 4 TVG (time-varied gain) curves are selectable to equalize responses from different depths, with 4 levels of gain compensation for deep range sounding.
• Three different sets of most-often used operating parameters can be stored into, and instantly recalled from, non-volatile memory.
• Three types of interference-fighting functions – noise reduction, interference rejection and jamming rejection – can be activated to ensure an undisturbed observation of echoes in crowded or noisy operating environments.
