The Airmar PM111 LHW is a CHIRP-ready, dual-frequency pocket/keel-mount transducer built for serious anglers who need both resolution and deep-water reach from a single unit. A fixed 25° wide beam across the entire 150–250 kHz high band delivers twice the coverage of typical narrow-beam high-frequency transducers, producing clean fish arches and strong target separation in the upper water column. The 2 kW low-frequency band pushes bottom returns down to 1,829 m (6,000'), making it equally capable offshore. Sold without a connector for custom installs in solid fiberglass hulls.

Features:

• Integrated depth and fast-response water-temperature sensor
• 2 kW low frequency (38–75 kHz) for exceptional deep-water performance: 19°–10° port-starboard beamwidth, 10°–5° fore-aft beamwidth, maximum depth 1,829 m (6,000')
• 1 kW high frequency (150–250 kHz) with fixed 25° constant beamwidth and maximum depth of 152 m (500')
• 137 kHz of total bandwidth from a single transducer
• Covers popular fishing frequencies of 50, 68, and 200 kHz plus all frequencies within the bandwidth
• Wide high-frequency beam provides superior shallow-water resolution, bottom detail, and fish-target separation
• Upper water-column fish detection enhanced by the constant wide beamwidth
• Urethane housing engineered for custom pocket/keel-cavity mounting
• Also available in an external mount configuration (R109LHW)
• Exclusive Xducer ID® technology
