Lowrance B117 0° 50/200kHz Thru-Hull Depth/Temp w/Blue Connector - 600W

Upgrade your boating experience with a transducer that delivers precise depth readings and water temperature data right when you need it. Designed for serious anglers and recreational boaters alike, this low-profile bronze thru-hull sensor mounts flush for a sleek installation while punching through hulls to provide crystal-clear sonar returns. Whether you're navigating shallow bays or probing deep offshore waters, its dual-frequency operation ensures you never miss the bottom or key structure below.

Superior Performance Across Water Depths

Crafted with boaters in mind, this transducer excels in varied conditions. The higher frequency shines in shallower waters, offering exceptional target separation for spotting fish, wrecks, or drop-offs with sharp detail. Switch to the lower frequency for deeper scenarios, where it maintains reliable bottom lock even in challenging environments like muddy bottoms or heavy currents. This versatility means one unit handles everything from coastal cruising to bluewater adventures, keeping your display fed with actionable intel.

Integrated temperature sensing adds another layer of utility. Track water temp changes to locate bait schools or predict fish behavior patterns, giving you an edge on the water. The bronze construction stands up to constant saltwater exposure, resisting corrosion and maintaining accuracy season after season.

Effortless Installation for Real-World Boats

Boat hulls aren't perfect, and this transducer gets that. The included rubber washer conforms to uneven surfaces, letting you achieve a watertight seal without drama. Its right-angle cable exit hugs the hull, minimizing snag risks and fitting tight spaces under decks or in crowded bilges. Low-profile design keeps drag low and your boat's lines clean—no bulky protrusions to foul lines or catch feet.

Compliant with industry safety standards, it installs confidently on planing hulls or sailboats starting around 25 feet. Think powerboats slicing through wakes or sail craft heeling in the breeze—this sensor keeps performing without interference from hull speed or angle.

Why Boaters Trust This Workhorse

For years, this model has been the go-to for those who demand reliability without fuss. It pairs seamlessly with compatible marine electronics, feeding clean data to your screen for enhanced charting and fishfinding. Forget fuzzy returns or signal dropouts; users rave about its consistent performance in real conditions, from choppy inlets to calm anchorages.

Maintenance is straightforward too. Periodic hull cleaning keeps it humming, and the durable housing shrugs off impacts from docking or trailering. Invest in gear that matches your passion for the water—precise, tough, and ready for whatever the day brings.

Real-World Applications and Tips

• Shallow Water Exploration: Use the high-frequency mode to map contours and spot structure in under 100 feet, ideal for inshore fishing or anchoring in unfamiliar spots.
• Deep Water底 Tracking: Low-frequency power ensures solid bottom contact beyond 500 feet, perfect for offshore trolling or navigation.
• Temperature Insights: Monitor thermoclines to position lures or baits where fish congregate, boosting your catch rates.
• Installation Pro Tip: Fair the leading edge slightly for optimal water flow, reducing cavitation and maximizing signal quality.
• Cable Management: Secure the right-angle connector away from high-traffic areas to prevent wear from foot traffic or gear.

Boat owners appreciate how this transducer integrates into their setup without dominating it. It's not just about the specs—it's about confidence on the water, knowing your depth and temp data is spot-on every trip.
