Airmar B175H 20° CHIRP 1 kW through-hull transducer

This is a high-performance through-hull transducer rated at 1 kW, designed for fish detection and detailed seabed analysis. It uses high-frequency CHIRP technology (High CHIRP) and features a 20° tilt to adapt to hulls with a pronounced deadrise angle.

The GARMIN AIRMAR B175H transducer operates over a high-frequency CHIRP range from 130 to 210 kHz. This wide bandwidth delivers highly detailed images of the seabed and targets.

The GARMIN AIRMAR B175H transducer has a nominal power output of 1 kW (1000 Watts). This high power ensures excellent water penetration and reliable target detection, even at intermediate depths.

Thanks to its High CHIRP technology and 1 kW power output, this fishfinder is particularly suited to sport and commercial fishing. It excels at detecting fish in the water column, identifying underwater structures, and analyzing bottom details, whether in shallow or mid-depth waters.

The GARMIN AIRMAR B175H transducer, with its 1 kW power output and High CHIRP technology, can typically detect depths up to approximately 240 to 300 meters (800 to 1000 feet), depending on water conditions and installation.

The CHIRP (Compressed High-Intensity Radiated Pulse) technology sends a continuous sweep of frequencies, ranging from the low to the high end of the specified range, rather than a single fixed frequency. The B175H transducer uses High CHIRP (130-210 kHz) to deliver exceptional resolution and target separation, enabling individual fish and bottom structures to be distinguished with remarkable clarity.

Traditional transducers emit a single signal at a fixed frequency, whereas CHIRP transducers like the B175H send a frequency sweep across a wide band. This approach allows CHIRP to collect far more data, delivering superior resolution, better target separation, and significant noise reduction, resulting in clearer and more detailed images on the display.

Yes, the B175H transducer performs very well in shallow waters. Its High CHIRP technology allows precise detection of fish and bottom structures, even at low depths, providing fine details and excellent target separation.

The GARMIN AIRMAR B175H High CHIRP transducer features a conical beam. The beam angle typically ranges from 15° to 9° at 130 kHz and from 9° to 5° at 210 kHz. A narrower beam at high frequency provides better target discrimination and seabed detail.

Yes, thanks to its High CHIRP technology and high resolution, the B175H fishfinder can distinguish individual fish, even when they are grouped in schools. This helps anglers better assess the size and behavior of targets.

The GARMIN AIRMAR B175H through-hull transducer features a bronze housing. This material is known for its durability and resistance to corrosion in marine environments, ensuring a long product lifespan.

The 20° tilt of the transducer is designed to compensate for the deadrise angle (or hull inclination) of your boat. This ensures the transducer’s beam is oriented perfectly vertically toward the seabed once installed, guaranteeing optimal performance and accurate readings.

A transducer with a 20° tilt is generally recommended for boats where the deadrise angle at the installation point is between 16° and 24°. It is essential to measure the deadrise angle of your hull to select the correct transducer tilt for proper installation and optimal performance.

Yes, as its name suggests, a through-hull transducer requires drilling a hole in your boat's hull for installation. The transducer body passes through the hull, and the transducer is then secured from both the inside and outside to ensure watertightness.

Installing this through-hull transducer typically requires specific tools, including a hole saw of the appropriate diameter for drilling the hull, clamping tools, marine sealant for waterproofing, and possibly tools for cable routing. It is strongly recommended to hire a professional for the installation if you are not experienced.

Yes, location is crucial. The transducer must be installed in an area where water flow is as laminar as possible, away from turbulence created by the propeller, keel, water intakes, or other appendages. The goal is to avoid air bubbles that could disrupt the transducer’s signal and reduce its performance.

This transducer is compatible with most Garmin chartplotters and fishfinders equipped with CHIRP technology and an 8-pin (or 12-pin with the appropriate Garmin adapter) transducer port. This includes series such as GPSMAP (CHIRP-compatible models), echoMAP CHIRP, and GSD 25 sounder modules.

The GARMIN AIRMAR B175H transducer (part number 010-11937-22) features an 8-pin Garmin connector. If your Garmin device has a 12-pin transducer port, a Garmin adapter (sold separately) will be required for connection.

The GARMIN AIRMAR B175H transducer is specifically designed and wired for use with Garmin systems. While the Airmar transducer is a universal base, the connector and impedance are optimized for Garmin devices. Using it with other brands would require specific adapters and would not always ensure optimal performance or full CHIRP functionality.

Yes, like all Garmin products, the AIRMAR B175H transducer comes with a standard manufacturer’s warranty. This warranty covers material and manufacturing defects under normal use conditions.
