JMC F-3000 Navigation Echosounder
Overview
The JMC F-3000 is a dual-frequency marine echo sounder tailored for navigation across a wide range of vessel types. Equipped with a bright 10.4″ VGA color display and compliant with IMO Resolution MSC.74(69), it meets rigorous maritime standards. It’s also approved by the Russian Maritime Register of Shipping, confirming its reliability and safety credentials.
Key Features
-
Dual-Frequency Operation
Offers selectable frequencies such as 50/200 kHz, 38/100 kHz, or specialized transducers (e.g., 135 kHz), providing versatility across shallow and deep waters. -
High-Resolution Display
10.4″ analog RGB TFT-LCD, VGA resolution (640×480), high brightness, and customizable background colors. -
Extensive Data Storage
Retains up to 24 hours of depth data in non-volatile memory, plus 10 minutes of live echogram recording, ideal for post-analysis. -
Wide Ranges and Auto Adjustments
Offers depth measurement from 5 to 1000 meters with automatic range selection, power control, and adjustable image feed rates (1:1 to 1:4 and freeze). -
Advanced Echo Processing
Features noise reduction (3 levels), echo threshold filtering (up to 5 levels), TVG/STC smoothing, and dynamic range control for crisp and clear echo visualization. -
Safety Alarms and Sensor Support
Includes depth and power loss alarms. Supports optional temperature sensors (T-200, T-300, T-400) and integrates latitude/longitude and water temperature input. -
System Integration & Printing
Supports NMEA-0183 interfaces (via RS-232C or RS-422), printer output for monochrome echogram printouts, and compatibility with external sensors. -
Flexible Power Options
Operates on 10–40 V DC (approx. 15W) or 110–220 V AC (approx. 20W), making it adaptable to various shipboard power systems.
