AIRMAR® B175L 12° CHIRP 1 kW through-hull transducer

This is a through-hull marine transducer designed to be installed through the hull of your boat. It is specifically optimized for depth and water temperature detection, using low-frequency CHIRP technology.

Its primary function is to provide accurate information on water depth and water temperature to your compatible fishfinder/depth sounder. It uses CHIRP technology for better target separation and clearer detection.

The « L » indicates that this transducer operates on low frequencies (Low CHIRP). This frequency band is particularly effective for deep-water detection, providing superior penetration and better detection of fish and seabed structures.

Yes, absolutely. Thanks to its low-frequency CHIRP technology ("L"), this transducer is specifically designed to deliver optimal performance in deep water, enabling reliable and detailed detection of the seabed and fish.

The Airmar B175L transducer housing is made of bronze. This material is robust and suitable for marine environments.

Yes, the GARMIN AIRMAR® B175L transducer is equipped with an integrated sensor that measures water temperature, in addition to its depth detection function.

The 12° tilt is a fixed angle compensation built into the transducer. It is designed to be installed on hulls with a deadrise angle between 8° and 15° so that the transducer’s beam is directed vertically toward the bottom, ensuring optimal performance.

Through-hull transducers generally offer the best performance as they are mounted directly in the water, without obstruction from the hull, which minimizes interference and ensures optimal transmission and reception of signals.

Yes, the GARMIN AIRMAR® B175L is well suited for sport fishing, particularly for deep-sea fishing. Its low-frequency CHIRP capability enables excellent fish detection and precise identification of underwater structures.

Being an "L" transducer (Low CHIRP), it operates in a low-frequency range. For the B175L, this range is typically 40 to 60 kHz, providing excellent deep penetration and a wide beam width.

The B175L transducer, with its bronze housing, is specifically designed for installation on fiberglass and wooden hulls.

The ideal location should be at the stern of the boat, in an area where the water flow is most laminar and free of turbulence (away from propellers, keels, and water intakes). It must also be accessible for installation and cable connection.

Yes, since this is a through-hull transducer, installation requires drilling a hole in the boat's hull to insert and secure the transducer body.

The transducer is usually supplied with the nuts, washers and gasket required for through-hull mounting. It is recommended to check the exact contents of the packaging upon receipt.

Yes, the transducer comes with an integrated cable. The standard length for this type of transducer is usually 10 meters, but it is always best to check the exact specifications of the model.

The Airmar B175L transducer is compatible with Garmin fishfinders equipped with CHIRP technology and supporting low frequencies (Low CHIRP), such as the GPSMAP and ECHOMAP Ultra series, as well as the GSD 25 sounder modules.

No, the B175L transducer has a bronze housing. Bronze transducers are not recommended for metal hulls (aluminum or steel) due to the risk of galvanic corrosion. Transducers with stainless steel or plastic housings are available for these hull types.

This transducer is ideal for small to medium-sized boats, particularly those with central consoles and hulls made of fiberglass or wood, where the deadrise angle is compatible with the 12° tilt.

Yes, like all Garmin products, the GARMIN AIRMAR® B175L transducer is covered by Garmin’s standard manufacturer warranty. This warranty ensures the product complies with specifications and covers manufacturing defects.
