Detailed description

Designed for deep-sea fishing, the internal Garmin AIRMAR® M265LH transducer is a 1 kW CHIRP fishfinder offering detailed seabed discrimination. Compatible with Garmin chartplotters and fishfinder modules equipped with a 12-pin CHIRP connector, it is ideal for vessels that do not require hull drilling.

Dual-Band CHIRP Technology for Optimized Performance

The Garmin AIRMAR® M265LH transducer features dual-band CHIRP technology with distinct frequencies for various applications. The low-frequency band (42-65 kHz) provides a 16° to 25° beam width and can reach depths up to 914 meters (3,000 feet). The high-frequency band (130-210 kHz) with a 6° to 10° beam width is suited for depths up to 304 meters (1,000 feet), ensuring precise target separation and seabed discrimination.

Robust Installation and Design

The internal installation of the Garmin AIRMAR® M265LH transducer requires no hull drilling, making it suitable for solid fiberglass hulls and towed or lifted boats. It fits hulls with a deadrise angle from 0° to 30°. Its plastic/urethane housing and acoustic window ensure durability in marine environments. The transducer weighs 5.2 kg (11.5 lbs) and comes with a 12-meter (39-foot) cable. It is recommended for boats up to 11 meters (36 feet) and provides depth data only.

Expert opinion

« Technical analysis of the CHIRP Airmar M265LH depth sounder »

The Garmin AIRMAR® M265LH transducer is a strategic choice for recreational boaters and anglers seeking a high-performance fishfinder without compromising the structural integrity of their hull. While its internal installation eliminates the need for drilling, it requires the addition of an oil-filled tank cut to match the hull’s deadrise angle. This step is critical to ensure optimal acoustic performance and prevent signal loss. This transducer is particularly suitable for solid fiberglass hulls, excluding sandwich or non-homogeneous structures that could disrupt signal transmission. With 1 kW of power and CHIRP dual-band technology (low and high frequencies), it excels at fish detection and seabed mapping, even at significant depths, up to 914 meters for the low-frequency range. It is optimized for compatible Garmin 12-pin units, ensuring seamless system integration and full utilization of the CHIRP capabilities of the chartplotter. Its use is recommended for vessels up to 11 meters, covering a wide range of rigid inflatables, day cruisers, and small cruising or fishing sailboats.

Frequently Asked Questions

Need help? Contact us

What is the Garmin AIRMAR® M265LH transducer?

The Garmin AIRMAR® M265LH is a 1 kW CHIRP transducer designed for deep-water fishing. It uses dual-band CHIRP technology (low and high frequency) to provide detailed discrimination of the seabed and targets.

What are the main characteristics of the CHIRP dual-band technology in this transducer?

The M265LH’s dual-band CHIRP technology uses two distinct frequency ranges: a low band (Low CHIRP) and a high band (High CHIRP). The low band excels in deep-water detection and bottom discrimination, while the high band delivers superior resolution for fish and near-surface structure detection.

What is the output power of this transducer?

The Garmin AIRMAR® M265LH transducer has an output power of 1 kW (1000 Watts).

Is the M265LH transducer suitable for deep-sea fishing?

Yes, the Garmin AIRMAR® M265LH is specifically designed for deep-sea fishing thanks to its 1 kW power and CHIRP dual-band technology, which provides excellent seabed penetration and discrimination.

What is the advantage of an internal transducer (oil-filled)?

The main advantage of an internal transducer is that it does not require drilling through the hull, preserving the boat's structural integrity and avoiding drag or maintenance issues associated with through-hull or transom-mount transducers.

Can the M265LH differentiate individual fish from schools of fish?

Yes, thanks to its CHIRP technology, the M265LH provides improved target discrimination, making it easier to distinguish individual fish, schools of fish, and underwater structures.

Is the M265LH transducer supplied with a fairing block?

No, the M265LH transducer is an internal (in-hull) model and is not designed to be mounted with a fairing block. It is installed inside the hull in an oil bath.

Which Garmin devices is the M265LH transducer compatible with?

The Garmin AIRMAR® M265LH transducer is compatible with Garmin chartplotters and fishfinder modules equipped with a 12-pin CHIRP connector.

What type of connector does the M265LH transducer have?

The M265LH transducer is equipped with a 12-pin CHIRP connector, specific to compatible Garmin devices.

Can I use this transducer with an older Garmin fishfinder that is not CHIRP?

No, the M265LH transducer is a CHIRP transducer and requires a CHIRP-compatible Garmin fishfinder or sounder module with a 12-pin connector to function properly.

Is it compatible with devices from brands other than Garmin?

The M265LH transducer is specifically designed with a 12-pin Garmin connector and is optimized for Garmin-compatible CHIRP systems. Compatibility with devices from other brands is not guaranteed and would require specific adapters not supplied.

Does the M265LH transducer require hull penetration?

No, the M265LH transducer is an internal (in-hull) model and does not require drilling the boat hull for installation. It is mounted inside the hull in a compartment filled with oil.

On which hull type can the M265LH transducer be installed?

The M265LH transducer is ideal for fiberglass or solid wood hulls. It is generally not recommended for double-bottom hulls or aluminum or steel hulls without prior consultation and specific considerations.

What type of oil should be used for the transducer oil bath?

For the oil bath of the M265LH transducer, it is recommended to use propylene glycol or mineral oil. These fluids ensure good sound wave transmission and protect the transducer.

How to ensure reliable signal transmission with an internal transducer?

For optimal signal transmission, it is critical to ensure the transducer is installed on a hull section free of air bubbles, internal reinforcements, and that the oil bath is bubble-free and properly filled. The location must be chosen to minimize turbulence under the hull.

Is the M265LH installation complex?

Installing the M265LH, while not requiring hull drilling, requires some expertise to select the correct location and ensure a bubble-free oil bath. It is recommended to carefully follow the installation manual provided by the manufacturer or to hire a professional.

Is the M265LH transducer supplied with the oil-bath mounting kit?

Yes, the Garmin AIRMAR® M265LH transducer is usually supplied with the necessary mounting kit to create the oil-filled well inside the hull, including the reservoir and cover.
