The Marinelite FP1021S is a professional 10-inch Color LCD Fish Finder designed for commercial fishing vessels, workboats, and offshore fishing operations. It utilizes advanced Digital Signal Processing (DSP) sonar technology to deliver high-resolution underwater images, enabling accurate detection of fish schools, seabed contours, and water depth in both shallow and deep-water environments.

The system features a 10-inch high-brightness color TFT LCD display with dual-frequency operation (50 kHz and 200 kHz), allowing operators to optimize performance for different fishing conditions. The 50 kHz frequency provides greater penetration for deep-water applications, while the 200 kHz frequency offers excellent target separation and detail in shallow waters. Independent gain control for each frequency ensures clear sonar images and improved fish detection.

The FP1021S supports multiple display functions, including dual-frequency display, single-frequency display, A-Scope, Bottom Lock, Auto Expansion, and Manual Zoom, making it easy to identify fish targets and distinguish them from the seabed. Built-in alarms for depth, voltage, and optional water temperature enhance operational safety, while NMEA 0183 (IEC 61162-1) communication allows integration with GPS and other marine navigation equipment.

Designed for continuous marine operation, the FP1021S operates from a 24 VDC power supply and complies with IEC 60945 environmental requirements. Its rugged construction, sunlight-readable display, and user-friendly interface make it suitable for commercial fishing boats, trawlers, coastal vessels, and workboats requiring reliable fish-finding and depth-monitoring performance.
