High-Wide CHIRP Performance for Superior Fish Detection
The Airmar TM185C Transducer is designed for anglers who demand exceptional target separation and coverage. Its high-wide CHIRP capability provides a broad frequency range of 150 kHz to 250 kHz, offering superior resolution and increased coverage under the boat. With a fixed 25° beamwidth, this transducer ensures more consistent and detailed imaging, making it the perfect choice for both inshore and pelagic fishing.
This transducer excels in shallow to mid-depth environments, detecting fish targets with unparalleled clarity and precision. Its urethane transom mount, paired with a stainless steel bracket, ensures secure installation on outboard and I/O-powered boats. Built to perform on planing and displacement hulls in fiberglass or wood, the TM185C delivers enhanced fishing performance for boats up to 10 meters (32 feet).
Advanced CHIRP Technology for Optimal Coverage
The TM185C High-Wide CHIRP transducer operates within a high-frequency band that covers a total bandwidth of 100 kHz. This wide range includes the popular 200 kHz frequency and enhances fish detection capabilities at depths up to 152 meters (500 feet). Its broad beamwidth provides twice the coverage compared to traditional narrow-beam transducers, making it ideal for spotting fish in the upper water column.
Additionally, Airmar’s Xducer ID® technology ensures seamless integration with a variety of marine electronics, automatically optimizing performance for enhanced sonar capabilities.
