Discover Crystal-Clear Underwater Visions with Active Imaging HD

Imagine gliding across the water, your boat cutting through waves, and suddenly, the screen lights up with razor-sharp images of fish hugging the bottom or darting along submerged structures. That's the power of the Lowrance Active Imaging HD Starboard Thru-Hull Transducer, designed specifically for dual transducer setups. This isn't just another sonar probe—it's your edge in spotting game fish from afar, navigating tricky drop-offs, and avoiding obstacles with confidence. Built for thru-hull mounting on the starboard side, it pairs seamlessly with its port counterpart to eliminate dead zones and deliver a full 360-degree view beneath and around your vessel.

What sets this transducer apart is its leap in resolution. Traditional imaging often leaves you guessing at fuzzy shapes, but HD technology pushes frequencies up to 1.2 MHz for SideScan and DownScan, revealing details like fin twitches and bait schools that were once invisible. Anglers report hauling in trophy walleye or bass because they can now pinpoint exactly where the big ones lurk.

Advanced Sonar Features That Outperform the Rest

• Ultra-High Definition Imaging: SideScan and DownScan at up to 1.2 MHz capture the finest details of fish, wrecks, and weed beds—far superior to standard 455 kHz options.
• Lowrance CHIRP Excellence: Medium and High CHIRP (83/200 kHz) provide exceptional target separation, distinguishing individual fish in dense schools without the clutter.
• FishReveal DownScan: Overlays fish-holding spots in bold color on DownScan images, making it effortless to spot keepers amid the structure.
• Robust Thru-Hull Design: Engineered for permanent installation through the hull, ensuring consistent performance regardless of boat speed or sea state.

These features combine into a 3-in-1 powerhouse: traditional CHIRP sonar for depth and coverage, plus crystal-clear imaging that transforms your display into a live underwater map.

Real-World Performance for Serious Boaters

In shallow bays where bass ambush baitfish near docks, the high-frequency SideScan paints a wide, detailed swath up to 300 feet per side, letting you mark waypoints without circling endlessly. Offshore, CHIRP slices through thermoclines to reveal suspended tuna or wrecks teeming with snapper. Users love how it excels in murky water—where clarity matters most—thanks to advanced signal processing that cuts noise and amplifies returns.

Why Dual Transducer Setup Shines

Mounting starboard and port transducers eliminates blind spots caused by hull curvature or prop wash. The result? Continuous, high-res coverage forward, aft, and to the sides, perfect for tournament pros or weekend warriors chasing stripers in coastal inlets.

Seamless Integration with Your Electronics

This transducer slots right into your setup if you're running HDS PRO series, or pair it with an S3100 module for HDS LIVE, Elite FS, or Simrad NSSevo3s and NSOevo3s. No guesswork—just plug into your network and watch FishReveal populate your screens. It's future-proofed for software updates that keep enhancing imaging algorithms.

Installation Insights and Pro Tips

Thru-hull installs demand precision, but this unit simplifies it with a streamlined housing that minimizes drag. Fair the mount for smooth water flow, and angle it slightly forward for optimal forward-facing scans. Saltwater anglers, apply anti-fouling paint to the face to ward off marine growth. Most boaters complete the job in a few hours with basic tools, gaining a setup that withstands rough conditions year after year.

Maintenance is straightforward: Rinse after every trip, inspect cables for wear, and store dry in off-seasons. With proper care, expect decades of reliable service.
