Airmar TM185M

The Garmin Airmar TM185M is a CHIRP transducer for transom mounting, designed for saltwater and freshwater fishing. It is optimized for shallow to medium depths and delivers high-resolution target detail and detailed bottom information, which is essential for fish and underwater structure identification.

The TM185M transducer uses CHIRP technology over a mid-frequency range, specifically between 85 and 135 kHz. This frequency band is ideal for fish detection at varying depths and for good target separation.

The Garmin Airmar TM185M has an RMS output power of 1 kW (1000 Watts). This high power provides excellent water penetration and reliable target detection even at significant depths.

The TM185M transducer provides depth and water temperature data. With its CHIRP technology, it also delivers highly accurate fish detection and detailed visualization of underwater structures and the seabed.

The Garmin Airmar TM185M transducer housing is made of urethane, a robust and durable material resistant to harsh marine environments and prolonged exposure to seawater.

The Garmin Airmar TM185M transducer comes with a standard 10-metre (approximately 33-foot) cable, providing sufficient flexibility for most transom installations.

The TM185M offers variable beam angles depending on the CHIRP frequency used. It has a beam angle of 16 to 24 degrees at 85 kHz and 11 to 16 degrees at 135 kHz, providing efficient coverage and good resolution.

Yes, the Garmin Airmar TM185M is designed to perform well in both freshwater and saltwater. Its versatility and CHIRP technology make it effective for detecting fish and structures in various aquatic environments.

The main feature of the CHIRP technology in the TM185M is its ability to emit a continuous sweep of frequencies over a given range (85–135 kHz). This provides resolution and target separation far superior to single-frequency transducers, delivering clearer and more detailed images of the seabed and fish.

The Garmin Airmar TM185M is a transducer designed for transom mounting. This type of installation is relatively simple and does not require drilling the hull below the waterline, making maintenance easier.

The TM185M transducer can be installed on most hull types, including fiberglass, wood, and metal hulls. For sandwich hulls (with a core), correct installation is crucial to prevent water absorption.

For optimal performance, the TM185M must be installed in an area with laminar water flow (without turbulence) under the hull. It is important to avoid zones near propellers, water intakes, or any other elements that may create air bubbles or disturbances.

Yes, installing the TM185M transducer on the transom requires drilling small holes in the transom to secure the mounting bracket. However, these holes are above the waterline and are then sealed to ensure watertight integrity.

When installing on a vee-hull, it is critical to mount the transducer between the chines or behind the last chine to ensure it remains immersed in undisturbed water flow, even at high speed. Incorrect mounting can result in signal loss.

The TM185M transducer is compatible with Garmin fishfinders and combos that support CHIRP mid-band frequencies. This typically includes the GPSMAP series and some EchoMAP CHIRP or STRIKER models that have an 8-pin CHIRP transducer port.

The Garmin Airmar TM185M (part number 010-12810-20) is fitted with an 8-pin Garmin connector. This connector is designed to plug directly into compatible Garmin devices without requiring an additional adapter.

No, the TM185M transducer is specifically designed to work with CHIRP technology and is not compatible with traditional fixed-frequency fishfinders that do not support CHIRP. To use the TM185M, a CHIRP-compatible Garmin device is required.

No, the TM185M transducer connects directly to compatible Garmin displays or sounders that already include CHIRP technology. An external sounder module is generally not required for operation unless the Garmin device lacks an integrated CHIRP module.

Yes, like most Garmin products, the Airmar TM185M transducer is covered by the manufacturer's standard warranty. This warranty provides protection against defects in materials or workmanship.
