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.

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.
