AIRMAR® M265LH

“I upgraded to the Garmin GT56UHD and the clarity is unbelievable. You can literally see fish moving around structure. Hard Rig Marine helped me pick the right setup and it’s been spot on since day one.”
Michael R. — Cairns, QLD -
“I’m not a tech person, but the team made it super easy to install my GT54UHD transducer. Works perfectly with my ECHOMAP — I’ve never had sonar this clear in the estuary before!”
Jenny L. — Mandurah, WA -
“The Airmar B175M changed my whole deep drop setup. Way better definition and stability compared to my old transducer. You get what you pay for — and these guys know their stuff.”
Ben T. — Newcastle, NSW
AIRMAR® M265LH: 1 kW Low/High CHIRP In-Hull Transducer (3,000 ft)
The AIRMAR® M265LH is the best-performing **1 kW in-hull transducer** available, designed for extreme deep-water fishing on non-cored fiberglass hulls. This professional-grade unit features robust **1 kW Traditional Sonar** with simultaneous **Low-CHIRP (42–65 kHz)** and **High-CHIRP (130–210 kHz)** operation. It reaches incredible depths up to **3,000 feet (914 meters)**, delivering exceptional bottom tracking and crisp image detail, without requiring hull penetration.
IN-HULL POWER & DUAL-CHIRP TECHNOLOGY
The M265LH is ideal for boat owners who require the power of a thru-hull without hull penetration, offering stable performance and noise rejection across all depths.
KEY SONAR & PERFORMANCE FEATURES
- In-Hull Installation: Designed to mount internally, making it easy to install and maintain without drilling holes below the waterline. (**Not recommended for cored-hull vessels**).
- Extreme Depth Capability: **1 kW power output** and Low-CHIRP (42–65 kHz) frequency band combine to reach depths up to **3,000 ft**.
- High-Resolution Detail: High-CHIRP (130–210 kHz) provides excellent target separation and crisp image detail in shallower/mid-water columns.
- Wide Deadrise Support: Accommodates hull deadrise angles from **0 to 30 degrees**.
CONNECTIVITY AND INTEGRATION
The M265LH is a heavy-duty sensor that requires a compatible CHIRP-enabled black box to unlock its full dual-frequency potential.
- **12-Pin Connector:** Uses the 12-pin connector for power and data output (requires compatible Garmin CHIRP port).
- **Temperature Data:** Outputs depth data, but **does not** output water temperature data due to its in-hull placement.
Inverell Boating Centre Expert Note:
The AIRMAR M265LH is the premier 1 kW in-hull transducer (Traditional CHIRP only), offering maximum depth performance (3,000 ft) and eliminating the need for hull holes. It is essential to ensure your hull is solid fiberglass (non-cored) and that your MFD or black box (e.g., GSD 26/28 [1]) has a compatible 12-pin port.
