AIRMAR® B175M, 12° Tilt

The AIRMAR® B175M transducer is a 1 kW through-hull transducer using CHIRP technology at mid-frequency (85-135 kHz). It is designed for demanding marine applications, providing highly detailed sonar images, accurate depth data, and water temperature. It is optimized for fiberglass and wooden hulls, significantly improving fish detection and navigation.

This AIRMAR® B175M transducer has a power output of 1 kW (1000 watts). This high power enables it to reach great depths and provide excellent target separation, even in challenging conditions.

The B175M transducer uses CHIRP technology at mid-frequency (M), covering a range from 85 to 135 kHz. This frequency band provides an excellent balance between deep penetration and target resolution, enabling detection of a wide range of fish.

Yes, the AIRMAR® B175M transducer includes a water temperature sensor. It provides accurate water temperature data, which is useful for fishing and navigation.

The CHIRP medium-frequency (M) technology provides an optimal balance between deep penetration and target resolution. It allows for the detection of fish at various depths with high clarity, distinguishing individual fish from schools and better identifying underwater structures.

No, the AIRMAR® B175M transducer is a through-hull model with a built-in 12° tilt. It is designed for direct installation without requiring additional external fairing on hulls with a deadrise angle between 8° and 15°.

This transducer is specifically compatible with fiberglass and wooden hulls. Its bronze construction makes it unsuitable and not recommended for aluminum or steel hulls due to the risk of galvanic corrosion.

This 12° tilt model is specifically designed for hulls with a deadrise angle between 8° and 15°. The built-in tilt compensates for the hull angle so the sonar beam is directed vertically downward, ensuring optimal performance.

The AIRMAR® B175M transducer is compatible with Garmin combos featuring CHIRP 1 kW capability and an 8-pin connector. It is generally compatible with the GPSMAP, echoMAP CHIRP, STRIKER Plus series and other compatible CHIRP models. It is always recommended to verify specific compatibility with your Garmin device model before purchase.

This transducer is fitted with an 8-pin Garmin connector. This connector is designed to plug directly into compatible Garmin fishfinders and displays, ensuring a reliable and secure connection.

No, this AIRMAR® B175M transducer is made of bronze and is not recommended for installation on aluminum hulls. Using bronze on an aluminum hull can cause severe galvanic corrosion. For aluminum hulls, it is preferable to use transducers made of stainless steel or plastic.

Yes, as a through-hull transducer, the B175M requires drilling a hole in your boat’s hull for installation. It is critical to follow the manufacturer’s instructions closely and use the appropriate tools to ensure a watertight and secure installation.

The ideal installation location is an area where water flows smoothly, without turbulence caused by propellers, keels, strakes, or other equipment. It should be mounted as close as possible to the boat’s centerline, forward of the propellers, to minimize interference and ensure a clear sonar reading.

Yes, the installation area must be clean, dry, and free of paint or antifouling. It is recommended to lightly sand the surface to ensure better adhesion of the sealant. The edges of the drilled hole must be chamfered and sealed with epoxy resin or a similar product to prevent water absorption by the wood or fiberglass, thereby ensuring hull integrity.

To ensure durable and reliable watertightness, it is recommended to use a high-quality marine sealant based on polyurethane or polysulfide, such as 3M 5200 or an equivalent product. Apply the sealant generously around the transducer body and on the contact surfaces with the hull, following the manufacturer's instructions for the sealant.

The B175M transducer is designed with a fixed 12° tilt. During installation, ensure the arrow or mark on the transducer body points toward the bow of the boat and that the transducer is securely fastened. The internal tilt compensates for the hull deadrise angle, so manual angle adjustment is unnecessary.

The AIRMAR® B175M transducer, like most Garmin products, comes with a limited two-year warranty from the date of purchase. This warranty covers defects in materials and workmanship under normal use conditions.

The warranty covers manufacturing defects and material defects under normal operating conditions. It does not cover damage caused by improper installation, an accident, misuse, unauthorized modification, repairs performed by unauthorized third parties, or external causes such as lightning or power surges.

To claim the warranty, you must contact Garmin’s customer service or the authorized dealer from whom you purchased the transducer. You will need to provide proof of purchase and a detailed description of the issue encountered. They will then guide you through the process for repair or replacement of your product.
