Product Overview

TM185C-HW CHIRP Transducer

Experience enhanced underwater coverage with the Airmar TM185C-HW CHIRP transducer. This transom mount transducer features a wide beam that operates within a high frequency range of 150-250 kHz, providing a consistent 25° beamwidth. This innovative design offers double the coverage compared to traditional high-frequency transducers, making it an essential tool for professional anglers.

In addition to improved performance for Chirp-ready echosounders, the TM185C-HW allows for greater bottom coverage and precise fish detection within the upper water column. With a constant beamwidth across the frequency spectrum, users can expect clearer and larger return images on their displays.

Expert Overview

The Airmar TM185C-HW Chirp Transducer is a transom-mount unit designed for marine applications, specifically targeting professional anglers and commercial fishing operations. It operates within a high-frequency CHIRP range of 150-250 kHz, providing a consistent 25-degree beamwidth. This design offers enhanced underwater coverage, approximately double that of traditional high-frequency transducers, which assists in more effective fish detection and bottom imaging. The transducer integrates a depth and fast-response water-temperature sensor, delivering essential data for navigation and fishing. With a 1kW RMS power rating, it is suitable for boats ranging from 8 to 12 meters (25 to 40 feet) and is compatible with outboard and I/O vessels, as well as fiberglass, wood, and metal hulls. The TM185C-HW-MM is engineered to provide clearer and larger return images on compatible CHIRP-ready echosounders, improving situational awareness in the upper water column and at depths of 600-800 feet.
