Airmar B164 Bronze Thru-Hull - 50/200 kHz - 1 kW - 20 Tilted Element - Requires Mix & Match Cable - B164-20-MM

B164 Bronze Thru-Hull - 50/200 kHz - 1 kW - 12 Tilted Element - Requires Mix Match Cable

20 tilted version for 16 to 24 hull deadrise angles. Step up to a 1 kWwithout a fairing! The 1 kW, flush-mount, Tilted Element transducer is perfect for fast, trailered vessels that cannot accommodate a High-performance Fairing. The flush-mounted, bronze housing extends less than 6.35 mm (1/4) below the hull so that it can sit on trailer rollers and bunks. The ceramic arrays are tilted within the housing, providing a perfectly vertical beam with maximum energy at the point directly below the boat.

The Airmar B164 Bronze Thru-Hull transducer is engineered for reliable performance on fast, trailered vessels that require efficient hull integration without compromising speed or maneuverability. Featuring a low-profile bronze housing that extends less than 1/4 inch below the hull, this transducer is specifically designed for boats with deadrise angles ranging from 16 to 24 degrees. Its 20-degree tilted element ensures a perfectly vertical beam, providing maximum energy concentration directly beneath the vessel for accurate depth and temperature measurements. This design makes it ideal for center-console and trailered boats where space and hydrodynamics are critical factors. The B164 offers dual-frequency operation with a wide 22-degree beamwidth at 50 kHz for deep-water performance up to 1,800 feet, and a narrower 6-degree beam at 200 kHz suitable for shallower depths up to 800 feet. Equipped with a 1 kW power rating, this transducer delivers fast, responsive readings for fishing, yachting, and recreational navigation. It interfaces seamlessly with any 600 W or 1 kW echo sounder, making it versatile for various marine electronics setups. The transducer includes built-in water-temperature sensing and patented Xducer ID technology, ensuring compatibility and ease of installation across different systems. Constructed from durable bronze and featuring a urethane acoustic window, the B164 is built to withstand harsh marine environments and provides consistent performance whether installed in fiberglass or wood hulls. The included 6.5-foot cable allows flexible positioning and connection options. Designed for vessels up to 36 feet long, the B164 transducer is a reliable choice for boaters seeking high-quality depth and temperature data with minimal impact on vessel hydrodynamics.

Features:

• Depth and fast-response water-temperature sensing

• 1 kW power output for strong signal transmission

• Dual-frequency elements: 50 kHz with a 22-degree beamwidth for deep water up to 1,800 feet, 200 kHz with a 6-degree beamwidth for shallower depths up to 800 feet

• Compatible with any 600 W or 1 kW echo sounder

• Engineered for center-console and trailered boats

• Low-profile bronze housing extends less than 1/4 inch below hull surface

• No effect on boat’s running performance due to hydrodynamic design

• Available in stainless steel housing for use in all hull materials

• Patented Xducer ID technology ensures system compatibility
