Lowrance 50/200 HDI Transom Mount Transducer f/HOOK Reveal

Upgrade your fishing adventures with the precision and clarity that serious anglers demand. This transom-mounted powerhouse delivers Hybrid Dual Imaging (HDI) technology straight to your HOOK Reveal unit, blending wide-area sonar coverage with pinpoint structure detail. Whether you're chasing bass in shallow bays or hunting trophy walleye offshore, it reveals what's below like never before—without the guesswork.

Unmatched Performance Under the Hull

Engineered for reliability on the water, this skimmer-style transducer sweeps a broad cone at lower frequencies for maximum target detection while dialing in high-resolution side-by-side views at higher bands. Picture this: you're idling over a reef, and suddenly submerged rocks, weed beds, and schooling fish pop into sharp focus. No more murky screens or missed opportunities— just actionable intel that puts fish in the livewell.

• Versatile Frequency Options: 50 kHz for deep-water power (up to 3,000+ feet in ideal conditions), 200 kHz for everyday precision, plus 455/800 kHz for DownScan Imaging that rivals photographs of the bottom.
• Built-in Temperature Sensor: Track water temp changes in real-time to pinpoint thermoclines where baitfish—and predators—congregate.
• Rugged Transom Design: Mounts cleanly on the stern, kicking water flow keeps it free of debris, ensuring consistent performance even at trolling speeds.

How HDI Transforms Your Sonar Game

HDI isn't just buzzword tech—it's the fusion of Broadband Sounder for traditional fish arches and exclusive DownScan Imaging for photo-like bottom scans. Split your screen to overlay both, and you'll spot bait balls suspended over drop-offs or individual crappie hugging timber. Anglers report doubling their catch rates in structure-heavy waters like rivers or coastal inlets because it cuts through clutter that lesser units miss.

Pro tip: In skinny water under 20 feet, crank up the 800 kHz DownScan for hyper-detailed weedline edges. Switch to 50 kHz when probing deep humps for suspended schools—versatility that adapts to your day on the water.

Seamless Setup for Any Boat

Everything you need arrives in the box: sturdy mounting bracket, stainless hardware, and 20 feet of cable for flexible routing to your console. Position it 1/3 from the transom's edge, parallel to the keel, and deadrise angle it right for bubble-free readings. Most installs take under an hour, even for DIYers. It's forgiving on stepped hulls or multi-motor setups, streaming data without interference.

Ideal Match for Everyday Warriors

Tailor-made for HOOK Reveal chartplotter/fishfinders, it unlocks full potential without adapters or compromises. Freshwater kayak jockeys love its sensitivity for panfish; offshore guys swear by its deep-water punch in the salt. Durable enough for rough chops, sensitive enough for finesse finesse tactics—it's the workhorse upgrade that pays dividends trip after trip.
