Airmar B175C-20-H 20d Tilt With Navico 9-Pin MM Cable

The Airmar B175C-20-H is a high - performance CHIRP high - frequency transducer with a Navico 9 - Pin Mix - N - Match cable. Model: B175C - 20 - H - 9N. It serves as both a depth and fast - response water - temperature sensor. With high - CHIRP from 150 kHz to 210 kHz, it offers 80 kHz of total bandwidth from a single transducer. Ideal for boats 8 m (25’) and above, it covers the popular 200 kHz fishing frequency and the whole bandwidth. Suitable for fiberglass or wood hulls, its ceramic elements are permanently tilted inside the housing to compensate for hull deadrise. This ensures the sonar beam is aimed straight down, maximizing echo returns and no fairing is needed. Flush/tilted transducers can be mounted through a hole in fiberglass, metal, or wooden hulls. High - frequency operation provides greater detail, perfect for shallower water and anglers fishing at depths less than 1500 feet. Specifications include a deadrise of 16 - 25°, urethane acoustic window, 1 kW @ 1% duty cycle power rating, 130 to 210 kHz - A (Broadband) frequency, 10° to 6° beam, and a max depth of 1000ft. The package includes a B175C - 20 - H - MM Transducer and an MMC - 9N Mix - N - Match Cable.

Using this Airmar transducer is easy. First, find a suitable location on your boat's hull (fiberglass, metal, or wood). Drill a hole and mount the transducer so the outside of the fitting is flush against the exterior hull surface. Connect the Navico 9 - Pin Mix - N - Match cable to your boat's sonar system. When using, you'll get detailed sonar images, especially in shallower water. Remember, this transducer is best for boats 8 m (25’) and above. Also, it works well for depths up to 1000 ft and is great for fishing at less than 1500 feet. For maintenance, regularly check the cable for any signs of wear or damage. Keep the acoustic window clean, as a dirty window can affect the sonar performance. If you notice any issues with the echo returns or temperature readings, check the connections and make sure the transducer is properly tilted to aim the beam straight down.
