KEY FEATURES & APPLICATIONS

High-Resolution Color Plotter: The 7-inch widescreen display offers a vivid "radar-style" view with color-coded AIS targets, allowing for much faster identification of dangerous vessels compared to monochrome screens.

Multi-GNSS Reception: By tracking multiple satellite constellations simultaneously, the SI-70A provides more reliable positioning and timing data, essential for busy shipping lanes.

User-Friendly Interface: Features a dedicated numeric keypad and one-touch function keys (F1–F4) for rapid access to menus, target lists, and message settings.

Internal Self-Diagnosis: An upgraded fault-diagnosis system continuously monitors internal PCB health and antenna status, alerting the crew immediately to any system failures.

Day/Night Display Modes: Optimized color palettes prevent eye strain during night watches while maintaining high visibility in direct sunlight.

Flexible Target Sorting: Navigators can sort the target ship list by MMSI, Distance, or Bearing (ascending/descending), or search directly by ship name.

Multilingual Menu: Supports English, Korean, Chinese, and Russian languages, making it a versatile choice for international crews.

TYPICAL CONDITION (USED/REFURBISHED)

Standard Components: Usually sold with the SI-70A Main Unit, GNSS-70 Antenna, and VHF Antenna. (Optional Terminal Box TB-70S may be included).

Technical Status: Refurbished units are typically tested for color LCD clarity (no dead pixels) and VHF transmit power consistency.

Retrofit Potential: Its wide voltage range (11-36V) makes it very easy to install on various vessel types without needing dedicated power converters.
