Manufacturer Information

Manufacturer: JMC (Japan Marine Communication Equipment Manufacturer)

Country of Origin: Japan

Equipment Type: Marine Echo Sounder

Application: Water Depth Measurement & Navigation Safety


Product Introduction

The JMC F-3000 Echo Sounder is a professional marine depth sounding system designed to provide accurate and continuous depth information beneath a vessel. It is an essential navigation instrument used onboard commercial ships, offshore vessels, fishing vessels, and passenger ships.

The system continuously transmits ultrasonic signals toward the seabed and calculates water depth based on the returning echo signal. This information helps bridge officers avoid grounding incidents and maintain safe under-keel clearance during navigation.

The JMC F-3000 is commonly installed onboard:

  • Cargo Ships
  • Bulk Carriers
  • Oil Tankers
  • Chemical Tankers
  • Offshore Support Vessels
  • Passenger Vessels
  • Fishing Vessels
  • Coastal Ships

What Is JMC F-3000 Echo Sounder?

The JMC F-3000 is a marine navigation instrument used to measure water depth beneath a vessel in real time.

The system provides:

  • Real-Time Depth Measurement
  • Seabed Tracking
  • Under-Keel Clearance Monitoring
  • Shallow Water Alarm Functions
  • Navigation Safety Support
  • Continuous Depth Display

The echo sounder works by sending ultrasonic pulses from a transducer mounted beneath the vessel. The reflected signal is received and processed to calculate the distance to the seabed.

This information is critical during:

  • Harbor Entry
  • Coastal Navigation
  • River Navigation
  • Shallow Water Operations
  • Offshore Operations

Main Features

Accurate Depth Measurement

Provides continuous and highly accurate water depth information.

High Visibility Display

Large display screen enables clear monitoring under bridge operating conditions.

Automatic Depth Tracking

Automatically follows seabed contours and changing depth conditions.

Shallow Water Alarm

Warns navigators when depth falls below preset safety limits.

Reliable Marine Construction

Designed for long-term operation in harsh marine environments.

Continuous Operation

Provides uninterrupted depth information throughout vessel operations.
