Garmin B164-20 20° 1kW Tilted Element Transducer w/6-Pin Connector

Elevate Your Fishing Game with Advanced Sonar Precision

Imagine gliding across the water with crystal-clear views of the underwater world, spotting structure and fish exactly where your boat points—without bulky hardware complicating your setup. The B164-20 tilted element transducer delivers that edge for serious anglers chasing big catches in deep waters. Engineered for high-speed boats and trailered vessels, this powerhouse unit combines raw 1kW sonar strength with smart design that keeps your hull sleek and trailer-ready.

Whether you're running offshore tournaments or scouting local hotspots, its flush-mount bronze housing barely kisses the hull surface, shrugging off trailer bunks and rollers like they're nothing. No more compromising on performance to save your boat from trailering wear—this transducer lets you fish hard and travel easy.

Core Technology: Tilted Element Innovation

The secret sauce here is the Tilted Element™ design from Airmar, tilted ceramic arrays that fire sonar beams straight down, maximizing energy on your target zone beneath the boat. Skip the fairing block entirely; this setup protrudes just a quarter-inch from the hull, perfect for vessels up to 25 feet that demand speed and agility.

At 50 kHz, you'll get a focused 20-degree beam ideal for scanning wide areas in depths up to thousands of feet. Switch to 200 kHz for pinpoint detail on closer targets. Paired with temperature sensing, it feeds your Garmin chartplotter real-time data for smarter decisions on the water.

Standout Features for Real-World Demands

• 1kW RMS Power: Punches through murky water and thermoclines for reliable bottom tracking and fish arches at extreme ranges.
• Dual-Frequency Operation: 50/200 kHz versatility covers shallow bays to deep bluewater hunts.
• Depth and Temperature Sensor: Integrated temp probe tracks water column changes to locate bait balls and species preferences.
• Bronze Flush Housing: Corrosion-resistant and low-profile—under 6.35 mm protrusion keeps drag minimal and hull intact.
• 6-Pin Connector: Seamless plug-and-play with compatible Garmin sounders.
• High-Performance Ceramics: Optimized for clear separation of targets, reducing clutter in complex environments like wrecks or reefs.

Why This Transducer Wins for Trailered Boats

Trailering means compromises—until now. Traditional thru-hull transducers with fairings demand careful handling to avoid damage, but the B164-20's rugged build laughs it off. Mount it forward in the hull for optimal water flow, and enjoy speeds over 30 knots without signal loss.

Users rave about its edge over lower-power units: deeper penetration in saltwater, sharper images on schools of pelagics, and fewer false readings around bait. For Garmin owners upgrading from 600W setups, the jump to 1kW feels like night and day—especially when paired with CHIRP-enabled units for even richer detail.

Installation Insights for Peak Performance

Dead simple for DIYers: Drill a clean 3-inch hole, bed in sealant, secure the hull nut, and route the cable cleanly. Aim for a forward-facing position below the waterline, away from strakes or thru-hulls that could aerate the signal. Pro tip: Fair the leading edge slightly with marine filler for ultra-smooth flow at high speeds.

Once wired to your Garmin black box or multifunction display, calibrate for your hull deadrise (up to 24 degrees), and you're scanning. Regular freshwater rinses keep it humming season after season in harsh marine conditions.

Real Angler Advantages

Fishermen targeting tuna, billfish, or wrecks swear by this for its no-nonsense reliability. It shines where others fade: heavy weather, fast drifts, or when you need to mark bottom structure precisely for jigging or trolling. Upgrade your electronics arsenal without redesigning your boat.
