AIRMAR® B175HW 20° Through-Hull Fishfinder 1 kW CHIRP

The Garmin AIRMAR B175HW transducer is a 1 kW through-hull transducer designed for fish detection. It uses CHIRP Wide High technology to deliver detailed performance, particularly in shallow waters, and excellent target separation.

This transducer has a 1 kW (1000 Watts) output power, providing effective penetration and detection capability in water.

The B175HW transducer operates across a CHIRP Wide-High frequency range from 150 to 250 kHz.

The B175HW transducer is particularly suited to fishing in shallow waters. Its CHIRP Broadband technology optimizes fish detection and target separation in these environments.

The CHIRP High-Wide (High-Wide CHIRP) technology uses a wide frequency band (150-250 kHz) to scan a larger area beneath the boat. This provides better coverage, more accurate fish detection, and excellent target separation, even at high speeds.

Yes, the Garmin AIRMAR B175HW is a through-hull transducer, which means it is installed by drilling through the boat's hull.

This transducer is specifically designed to be installed on fiberglass and wooden hulls.

The 20° tilt of the AIRMAR B175HW transducer is fixed. It is designed to compensate for the keel angle of boats with a hull angle of approximately 16° to 24°.

A "deep-water" transducer beam offers broader coverage beneath the boat, which is particularly useful for locating fish schools and structures over a larger area, especially in shallow waters. This improves situational awareness beneath the boat.

Yes, in addition to fish detection, the B175HW fishfinder provides detailed information about seabed structure thanks to its CHIRP technology, which is useful for navigation and fishing zone scouting.

Yes, the AIRMAR B175HW transducer is equipped with a water temperature sensor, allowing your compatible Garmin device to display this information.

The 20° tilt is designed to compensate for the keel angle (or hull heel) of the boat. This ensures the transducer element is oriented vertically toward the seabed, guaranteeing optimal performance of the depth sounder’s beam.

Installing a through-hull transducer like the B175HW requires drilling the boat's hull. It is strongly recommended to use a qualified professional to ensure a correct, watertight installation optimized for performance.

Yes, it is recommended to apply a water-based antifouling to the active surface of the depth sounder transducer to prevent marine growth, which could degrade its performance. Ensure the antifouling used is compatible with transducers and solvent-free to avoid damaging the plastic.

For optimal performance, the transducer must be installed in an area free of turbulence, away from propellers, the keel, strakes, and any other source of air bubbles. The ideal location is typically toward the bow of the boat, in an area where the water flow is as laminar as possible.

When installing on a wooden hull, it is crucial to ensure perfect watertightness to prevent any water infiltration. The use of appropriate marine sealants is essential, and treating the wood around the hole may be advisable for improved durability.

The AIRMAR B175HW transducer is compatible with Garmin fishfinders and GPS/fishfinder combos equipped with CHIRP technology and the correct transducer port. It requires a device capable of handling CHIRP High-Wide frequencies (150–250 kHz).

No, the B175HW transducer is specifically designed for CHIRP technology. To achieve all its performance, it must be connected to a CHIRP-compatible fishfinder or chartplotter.

The AIRMAR B175HW transducer is designed to connect to Garmin devices compatible with CHIRP. The connector type is Garmin-specific, so it is important to verify compatibility with your device’s port or whether an adapter is required.

Yes, the AIRMAR B175HW transducer is covered by Garmin's standard manufacturer warranty. This warranty covers protection against manufacturing defects.
