Airmar - M135C-M Transducer Medium CHIRP Transducer

Advanced CHIRP Technology for Superior Marine Performance

The Airmar M135C-M Transducer is designed for serious offshore and freshwater anglers looking for high-performance sonar technology. This 1 kW transducer operates within the medium CHIRP frequency range of 85-135 kHz, providing exceptional target resolution and clarity in both shallow and medium-depth waters. With a depth capability of up to 1,500 feet (457 meters), it is perfect for navigating murky or coastal waters with precision.

Its innovative in-hull design eliminates any protrusions on the boat's exterior, making it an ideal choice for trailered or lifted boats. This transducer is optimized for solid core fiberglass hulls on boats up to 25 feet. Featuring Airmar’s exclusive Xducer ID® technology, it seamlessly integrates with compatible marine electronics for accurate performance adjustments.

Precision Engineering for Maximum Sonar Clarity

The M135C-M transducer utilizes an advanced urethane housing that is filled with eco-friendly antifreeze, ensuring optimal sound transmission through fiberglass hulls. The plastic mounting flange allows for secure placement and an adjustable dead rise offset between 2° and 20°, ensuring the sonar beam is properly aligned for accurate readings.

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.
