Airmar M265 CHIRP In-Hull Transducer - Low/High - No Connector

Brand: Airmar
Part Number: M265C-LH

Rely on Airmar’s new broadband transducers for your ultimate fishing mission. Whether you’re a commercial fisherman, charter captain, or tournament angler, there’s a new game in town! CHIRP transducers enable bottom detection down to 3,000m (10,000’) with 5 to 10 times greater detail and resolution so precise it’s possible to distinguish between individual baitfish, game fish, and underwater structures. One transducer delivers up to 103 kHz of total bandwidth in just one installation, saving customers time and money.

An in-hull model in the CHIRP product line, the M265 L/M, and L/H CHIRPS across the following bandwidths:

  • Low & High-Frequency (LH)
    • Low—Chirps from 42 kHz to 65 kHz, 25° to 16° beamwidth
    • High—Chirps from 130 kHz to 210 kHz, 10° to 6° beamwidth
  • Low and Medium Frequency (LM)
    • Low—Chirps from 42 kHz to 65 kHz, 25° to 16° beamwidth
    • Medium—Chirps from 85 kHz to 135 kHz, 16° to 11° beamwidth

Medium-frequency benefits include the ability to sound deeper than the high-frequency, along with better target resolution than the low-frequency.
