AIRMAR® B175H, 12° tilt

The Garmin AIRMAR B175H transducer is a high-frequency CHIRP through-hull transducer. It is designed for fiberglass and wooden hulls, providing precise detection capabilities for navigation and fishing. Its 12° tilted element compensates for the hull angle, ensuring a horizontal beam orientation without requiring an external fairing block.

This transducer uses high-frequency CHIRP technology. CHIRP (Compressed High-Intensity Radiated Pulse) sends a frequency sweep across a wide band, providing better target resolution, superior fish separation, and improved image clarity compared to traditional fixed-frequency transducers.

The 12° tilt of the transducer element is designed to compensate for the deadrise angle (the hull angle relative to horizontal) of boats. This ensures the depth sounder’s beam is perfectly horizontal toward the seabed, providing optimal detection without requiring an external fairing block.

A high-frequency CHIRP transducer offers several advantages:

Accurate detection: Enhanced ability to distinguish individual targets.Fish separation: Allows differentiation between fish and structures.Superior image clarity: Sharper and more detailed images of the seabed and structures.Performance in shallow to mid-depth waters: Ideal for varying depths with excellent resolution.

The Garmin AIRMAR B175H transducer is specifically designed for installation on fiberglass and wooden hulls. It is generally not recommended for aluminum or steel hulls without a specific adapter.

No, the Garmin AIRMAR B175H transducer is designed with a 12° tilted transducer element. This self-compensating design eliminates the need for an external fairing block to correctly orient the beam, simplifying installation and reducing drag.

The B175H transducer is primarily used for navigation and fishing. It allows precise fish location, identification of underwater structures, seabed mapping, and safer navigation by providing depth and seabed composition data.

A through-hull transducer like the B175H is installed by drilling a hole in the boat’s hull, providing a more stable reading with less susceptibility to turbulence, especially at high speeds. A transom-mounted transducer is attached to the outside of the transom, which is generally easier to install but can be affected by water turbulence.

Yes, the Garmin AIRMAR B175H transducer comes with an integrated connection cable, ready to be connected to your compatible Garmin equipment.

Installing a through-hull transducer involves drilling a hole in the boat’s hull at a strategic location, inserting the transducer body, and securing it firmly with the provided nuts and washers while ensuring a watertight seal. It is essential to strictly follow the detailed installation instructions provided by the manufacturer or to hire a professional to ensure a correct and secure installation.

Yes, the choice of location is crucial. The depth sounder transducer must be installed in an area where it is permanently submerged, away from turbulence generated by the propeller, keels, strakes, or other hull appendages. The ideal location is often toward the bow and amidships, in an area where the water is calmest, to ensure clear readings without interference.

For the installation of the AIRMAR B175H transducer, you will generally need the following tools:

An electric drill. Drill bits suited to the size of the transducer’s hole. A high-quality marine sealant (mastic). Wrenches to tighten the fittings. Surface cleaner and rags. The installation manual supplied with the transducer will detail the exact list of required tools and materials.

While it is technically possible to install the transducer yourself by carefully following the instruction manual, it is strongly recommended to use a professional if you lack experience in hull drilling or installing marine equipment. Incorrect installation can lead to leaks or poor transducer performance.

The AIRMAR B175H transducer is compatible with a wide range of Garmin fishfinders and combos equipped with CHIRP technology and a compatible transducer port. For precise compatibility, it is recommended to consult the specific compatibility list on the Garmin website or in your Garmin device manual.

The Garmin AIRMAR B175H transducer is equipped with a Garmin-specific connector designed to fit the transducer ports of Garmin devices compatible with CHIRP. The connector is a standard type used by Garmin for its CHIRP transducers.

Yes, the Garmin AIRMAR B175H transducer is covered by Garmin’s standard manufacturer warranty. This warranty covers repair or replacement of the product in case of manufacturing defects, subject to Garmin’s terms and conditions.

Upon delivery, the package generally contains:

The Garmin AIRMAR B175H through-hull transducer with its integrated cable.The mounting hardware required (nuts, washers, etc.).The installation and user manual.

The B175H transducer, being a high-frequency CHIRP transducer, is particularly effective for detecting precise targets and separating fish in shallow to mid-depth waters. For deep-sea fishing at very great depths, other low- or mid-frequency CHIRP transducers may be more suitable, but the B175H remains high-performing for many coastal and offshore applications.
