Unlock Crystal-Clear Fishfinding with Active Imaging HD

Imagine gliding across the water, your eyes locked on a display that reveals every hidden fish arch and submerged structure in stunning detail. The Lowrance S3100 Sonar Module transforms your HDS LIVE or Elite FS setup into a powerhouse for spotting fish like never before. By integrating high-frequency sonar up to 1 MHz, it combines Lowrance CHIRP technology with SideScan and DownScan Imaging to paint the underwater world in high-definition clarity. This isn't just about seeing more—it's about confidently targeting the biggest catches, whether you're chasing bass in shallow coves or tracking schools in deeper waters.

For serious anglers, the edge comes from details that matter. Traditional sonar often blurs the line between fish and debris, but with this module, you get images sharp enough to distinguish species and structure types, boosting your success rate on every trip.

FishReveal SideScan: Spot Fish Effortlessly on Both Sides

One of the game-changers is FishReveal SideScan view, now extended to HDS PRO, LIVE, and Elite FS displays. Picture this: high-frequency SideScan delivers intricate details of the bottom and cover extending far beyond your boat, overlaid with CHIRP's superior target separation. Fish pop as vivid yellow arches against a blue backdrop, eliminating guesswork. No more mistaking baitfish swarms for your trophy catch—FishReveal merges the best of both worlds into one intuitive screen.

Anglers report hooking more fish faster because this view reveals fish hugging structure on port and starboard sides, perfect for trolling or drifting in unfamiliar territory.

Dual 1kW Channels for Multi-Depth Mastery

Equipped with two fully independent 1kW sonar channels, the S3100 lets you hook up to two extra transducers, allowing simultaneous tracking across varied depths. Combine any two CHIRP frequency ranges—like a shallow 83/200 kHz for surface action and a deeper 50 kHz for bottom dwellers—and never miss a layer. Wide-angle transducers expand your coverage, sweeping broader areas to locate hotspots quicker.

This setup shines in diverse environments, from coastal bays teeming with flounder to offshore wrecks holding snapper, giving you the flexibility to adapt on the fly.

Stable Images in Any Conditions with Heave Compensation

Rough seas or choppy lakes can scramble sonar readings, but integrated heave compensation stabilizes images by adjusting for your boat's pitch and roll. The result? Consistent, readable returns even when waves are pounding. This feature alone can turn a frustrating outing into a productive one, keeping your focus on fishing rather than fighting the display.

Seamless Integration and Expanded Capabilities

With 1GB Ethernet connectivity, the S3100 plugs into your network effortlessly, supporting Ethernet expansion for future upgrades. It's built tough for marine life, ensuring reliable performance season after season. Pair it with your existing Lowrance ecosystem to elevate bottom tracking, fish arches, and structure ID across the board.

Pro tip: Mount transducers strategically for optimal coverage—forward-facing for live scoping or shaft-mounted for side coverage—and calibrate in calm water for peak accuracy.

Ready to Deploy: Simple Setup for Big Results

Getting started is straightforward. Connect via the included Ethernet and power cables, integrate with your display, and dive into advanced sonar modes. This module empowers kayak anglers, bass boats, and center consoles alike, making professional-grade imaging accessible without complex rewiring.
