AIRMAR® B175L, 20° tilt

The Garmin Airmar B175L transducer is a high-performance through-hull model designed for accurate depth and water temperature detection. It features a fixed 20° tilt to match your boat’s keel angle.

The fixed 20° tilt is designed to compensate for the keel angle of hulls with a deadrise between 16 and 24 degrees. This feature ensures the transducer beam is correctly oriented toward the seabed, eliminating the need for a fairing block.

This transducer can provide accurate data on water depth and water temperature.

The Airmar B175L transducer uses CHIRP Low Frequency technology, providing excellent target detection and deep water penetration.

No, the Airmar B175L transducer is not supplied with a fairing block. Its fixed 20° tilt is specifically designed to compensate for the keel angle, making a fairing block unnecessary for compatible hulls.

Low-frequency CHIRP technology offers several advantages for fishing, including:

Better target separation, allowing individual fish to be distinguished. Excellent deep penetration, ideal for offshore fishing. Reliable bottom detection, even in difficult conditions.

Yes, thanks to its Low Frequency CHIRP technology, the Airmar B175L transducer is particularly well suited for deep-sea and deep-water fishing, providing superior detection and depth penetration.

The Garmin Airmar B175L is a through-hull transducer, meaning it is installed by drilling a hole through the boat's hull.

The B175L transducer measures both water depth and water temperature, providing two essential pieces of information for navigation and fishing.

This transducer is an Airmar model, a brand known for its marine transducers, distributed under the Garmin brand.

The Airmar B175L transducer is optimized for installation on fiberglass and wood hulls.

This transducer is specifically designed for hulls with a deadrise angle (V) between 16 and 24 degrees, due to its fixed 20° tilt.

The Airmar B175L transducer is compatible with Garmin fishfinders and combos that support CHIRP Low Frequency technology. It is recommended to verify specific compatibility with your Garmin device model.

The product is optimized for fiberglass and wood hulls. Installation on other materials such as aluminum or steel may not deliver optimal performance or may require specific considerations and additional precautions to prevent corrosion or interference.

No, the Airmar B175L transducer is specifically designed to work with CHIRP low-frequency systems to fully exploit its capabilities and achieve the best performance.

Installing a through-hull transducer typically involves the following steps:

Select an optimal location on the hull.Drill an appropriately sized hole.Insert the transducer and secure it firmly.Ensure a watertight seal with marine sealant.Connect the cable to the fishfinder.It is strongly recommended to consult the detailed installation manual and, if possible, hire a professional.

No, thanks to its fixed 20° tilt, the Airmar B175L transducer is designed to compensate for the keel angle of compatible hulls without requiring the addition of a fairing block.

Installing this transducer is the simplest and most effective solution for hulls with a deadrise angle (V) between 16 and 24 degrees, as its 20° tilt is specifically optimized for this range.

Yes, to ensure correct installation, perfect hull sealing, and optimal transducer performance, it is strongly recommended to have the installation carried out by a qualified marine electronics professional.

When installing on a wooden hull, take extra precautions to ensure lasting watertightness and protect the wood from moisture. It is often recommended to apply layers of epoxy resin or a specific sealant around the edges of the drilled hole before installing the transducer to prevent water infiltration and wood rot.
