Airmar - TM185C Transducer High Wide CHIRP Transducer

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.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
