AIRMAR® B175HW, 0° tilt

The HW designation stands for High-Wide. It indicates that the transducer uses CHIRP technology over a high-frequency range (150-250 kHz) with a wide beam. This feature is ideal for detecting fish in the upper water column and for extended coverage beneath the boat.

The AIRMAR B175HW transducer operates on a high-frequency CHIRP range, specifically from 150 to 250 kHz. This wide bandwidth provides excellent target separation and high image clarity.

The Garmin AIRMAR B175HW transducer is a 1 kW (1000 Watts) unit. This high power ensures strong performance at depth and reliable target detection, even in challenging conditions.

The AIRMAR B175HW transducer provides essential data for navigation and fishing. It can measure and transmit water depth and water temperature.

The main advantage of CHIRP High-Wide technology is its ability to provide a constant and wide 25° beam angle across its entire frequency range. This enables:

Wider coverage beneath the boat, increasing the chances of detecting fish.Better detection of fish in the upper water column.Improved target separation, allowing individual fish to be distinguished from schools of fish or structures.

The AIRMAR B175HW transducer features a constant 25° beam angle across its entire frequency range (150–250 kHz). This wide angle is designed to maximize coverage beneath the boat and simplify fish detection.

No, the Garmin AIRMAR B175HW transducer is specifically designed with a Garmin 12-pin connector and is optimized to work with Garmin CHIRP-compatible fishfinder systems. It is not directly compatible with devices from other brands without non-standard adapters or modifications.

Yes, the B175HW sounder can be used with a compatible Garmin external CHIRP 1 kW sounder module, such as the GSD™ 25. This allows adding advanced sounder capabilities to existing Garmin navigation systems.

The B175HW transducer with 0° tilt is specifically designed for hulls with a deadrise angle between 0° and 7°. The 0° tilt means the transducer is designed to be flush-mounted on the hull, compensating for small deadrise angles so the beam is directed vertically downward.

Yes, as it is a through-hull transducer, installing the Garmin AIRMAR B175HW requires drilling a hole in your boat’s hull. This hole allows the transducer body and its cable to pass through the hull, ensuring optimal exposure of the transducer element to the water.

The Garmin AIRMAR B175HW transducer is optimized and recommended for installation on fiberglass and wood hulls. These materials allow for efficient transmission of acoustic signals.

The B175HW transducer is not directly suitable for aluminum hulls. Bronze transducers, such as the B175HW, can cause galvanic corrosion if installed directly on an aluminum hull. For installation on aluminum, specific stainless steel or plastic transducers with appropriate isolation kits would be required, or mounting via a pocket or shoe.

To ensure correct installation and avoid air bubbles that could disrupt the depth sounder’s performance:

Select a mounting location where the water flow is smooth and free of turbulence.Clean the hull surface thoroughly before installation.Apply high-quality marine sealant around the depth sounder body and hull hole, following the manufacturer’s instructions.Tighten mounting nuts gradually and evenly to ensure a perfect seal and prevent air entrapment.

Yes, it is recommended to apply antifouling to the submerged part of the depth sounder to prevent the buildup of marine organisms, which could affect its performance. However, it is crucial to use a water-based antifouling. Copper-based or solvent-based antifoulings can damage the transducer or reduce its effectiveness.

The Garmin AIRMAR B175HW transducer package typically includes the following items:

The AIRMAR B175HW transducer with integrated cable.The mounting and installation kit (including nuts, washers, and gaskets).The product documentation (installation and user manual).

In accordance with European legislation, the Garmin AIRMAR B175HW transducer is covered by a mandatory two-year (2) legal conformity warranty from the date of purchase. This warranty covers manufacturing and material defects under normal conditions of use.
