Furuno LS4100 Fish Finder

Overview Furuno LS4100 Fish Finder

Furuno LS4100 Fish Finder is a dedicated marine fish finder for skippers who want clear bottom and target information without moving sonar to a multifunction display. It combines 5-inch Silver Bright Monochrome LCD with Dual Frequency 50 kHz and 200 kHz and 300W RMS (2,400W Peak-to-Peak).

This model suits smaller fishing boats and coastal craft that need straightforward sonar control, readable returns, and dependable depth tracking. Source data includes Up to 3,000 Feet; 12 User Waypoints (Mini Navigator).

Key Features

• Dedicated fishfinder display: 5-inch Silver Bright Monochrome LCD focuses the screen on sonar returns without the clutter of a multifunction interface.
• Dual-frequency operation: Dual Frequency 50 kHz and 200 kHz gives a choice between broader deep-water coverage and finer shallow-water detail.
• Sonar output: 300W RMS (2,400W Peak-to-Peak) supports bottom tracking and target detection for coastal and deeper fishing use.
• Depth range: Up to 3,000 Feet is useful when moving between inshore structure and deeper water.
• Basic navigation support: 12 User Waypoints (Mini Navigator) allows the sounder to keep a small set of marks for repeat spots.

Applications

• Small fishing boats and coastal craft that want a dedicated sounder with straightforward controls.
• Bottom reading over reefs, ledges, wrecks, and changing contours using 50/200 kHz sonar views.
• Users who prefer a separate fishfinder screen instead of sharing sonar pages on a chartplotter.
