Bronze through-hull profiled depth/temperature transducer B175M Wide 1000W 20° beam

The Raymarine B175M Wide (reference A80801) is a bronze through-hull profiled depth sounder designed to measure water depth and temperature. It uses Medium CHIRP technology and features a Wide beam for extended coverage beneath the vessel. Its power output is 1000W.

This depth sounder has two main functions:

Depth measurement: It detects seabeds and underwater structures.Water temperature measurement: It provides accurate data on the temperature at the depth sounder's location.

The B175M Wide depth sounder is made of bronze. This material is particularly well-suited for fiberglass or wooden hulls, ensuring durability and performance in a marine environment.

The Raymarine B175M Wide transducer has a power output of 1000W (1 kW). This high power enables better water penetration and reliable target detection, even at significant depths.

The B175M Wide fishfinder uses Medium CHIRP technology, covering a typical frequency range of 85 to 135 kHz. This band provides a good balance between deep penetration and target discrimination.

The term 'Wide' (wide) indicates that this transducer emits a wide beam, typically around 25° in constant width across its frequency range. A wide beam provides broader coverage under the boat, increasing the chances of detecting fish schools and underwater structures.

CHIRP technology provides several significant advantages for fishing and navigation:

Better target discrimination: It allows clearer distinction between individual fish, schools of fish, and seabed structures.Improved resolution: Seabed images are sharper and more detailed.Less noise: The signal is cleaner, reducing interference.Better penetration: It can reach greater depths with superior clarity.

The B175M Wide bronze fairing through-hull depth sounder is specifically designed and recommended for fiberglass and wooden hulls. Installation requires drilling through the hull.

The B175M Wide transducer features an internal element tilted at 20°. This angle is generally suitable for hulls with a deadrise angle between 16° and 24°. This design ensures the transducer beam is correctly aligned with the hull bottom without requiring an external fairing block for most installations within this range.

No, thanks to its internal element angled at 20°, this transducer is designed to compensate for the deadrise angle of the hull (between 16° and 24°) and generally does not require an external fairing block to ensure optimal performance.

No, this transducer is compatible with Raymarine navigation and fishfinding systems that support CHIRP technology. This includes series such as Axiom Pro, Element HV/S, and other Raymarine chartplotters/depth sounders equipped with a compatible CHIRP sounder module.

In general, this transducer is designed for use with Raymarine-compatible CHIRP equipment due to its specific connector (Raymarine 10-pin) and optimized technology. Using it with other brands would require specific adapters and would not guarantee optimal performance.

CHIRP transducers differ by their frequency bands:

Low CHIRP (L): Uses low frequencies (e.g. 25-50 kHz), provides excellent deep penetration but lower resolution.

Medium CHIRP (M): Uses mid frequencies (e.g. 85-135 kHz for the B175M), offers a good balance between penetration and target discrimination, ideal for coastal and offshore waters.

High CHIRP (H): Uses high frequencies (e.g. 150-240 kHz), provides excellent target discrimination and fine details in shallower waters.

The streamlined design of this through-hull depth sounder is specifically engineered to minimize drag in the water. This helps maintain the boat's hydrodynamic performance and ensures stable data readings, even at varying speeds.

Installing a through-hull transducer requires drilling the hull and ensuring perfect watertightness. To guarantee safety, optimal transducer performance, and hull integrity, it is highly recommended to have the installation carried out by a qualified marine electronics professional.

With its CHIRP mid-band technology and wide beam, the B175M Wide improves fish detection by providing:

Better target separation to distinguish individual fish.Extended coverage beneath the boat to locate fish schools and structures.Reduced noise for clearer images on the display.

The Raymarine B175M Wide transducer is typically supplied with a 10-metre (approximately 33-foot) cable to facilitate connection to onboard electronic equipment.

Yes, with its 1000W power, CHIRP technology with mid-band, and ability to provide accurate depth and temperature data, the B175M Wide fishfinder is well suited for coastal and deep-sea fishing applications, offering excellent target and underwater structure detection.
