FEATURES
Navigational Echo Sounder
- Dual-Frequency Depth Measurement: Operates on 50 kHz and 200 kHz frequencies — allowing accurate depth measurement at different water conditions, with the option to display both fore and aft depth readings when using two transducers.
- Multiple Display Modes & Data History: Provides NAV mode (real-time depth echo), OS DATA mode (depth + own-ship data when connected to GPS/EPFS), and HISTORY mode (stores and displays depth history up to 24 hours).
- High-Contrast 8.4" Color Display: 8.4-inch color LCD ensures clear readability; echo with adjustable color schemes enhances visibility in various lighting conditions.
- Alarm & Safety Functions: Generates visual and audible alarms when water depth falls below a preset threshold — critical for avoiding groundings or underwater hazards.
- Data Recording & External Interfaces: Stores up to 24 hours of depth data (with 5-sec recording interval), supports optional printer or PC connection for logging, printing, and playback of echograms. Compatible with external displays (e.g. remote units) and standard marine communication protocols.
