Airmar PM275LH-W Pocket/Keel-Mount CHIRP Transducer for Raymarine

Upgrade your sounder to a serious fishfinding machine!

The Airmar PM275LH-W Pocket/Keel-Mount CHIRP Transducer is a pocket or keel-mounted CHIRP transducer, ideal for sportfishing and commercial vessels 8 m (25 ft) and up. This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, with High CHIRP at a constant 25° beam width for the best resolution and coverage in the upper water column and in shallower depths.

Dual Channel CHIRP
Using pulsed transmissions swept across a range of frequencies, CHIRP technology delivers target resolution and depth penetration superior to traditional single-frequency sonar. This dual-channel CHIRP transducer operates in the 42-65 kHz Low CHIRP frequency range with a 25-16° beam width, and the 150-250 kHz High CHIRP frequency range with a 25° beam width. With Low CHIRP, the PM275LH-W provides an operating depth of up to 1200 m (4000 ft).

Wide Angle CHIRP
Ideal for anglers, the PM275LH-W’s wide-angle technology delivers a constant 25° beam width across the transducer’s 150-250 kHz High CHIRP frequency range. This achieves up to double the coverage beneath your boat, and provides enhanced fish detection in the upper water column, versus the narrower beam of other high-frequency CHIRP transducers.

Depth/Temperature
One sensor does it all. Able to measure both depth and temperature in a single package, the PM275LH-W simplifies installation and requires just one connection to your echosounder module or multifunction display.

Mounting
The PM275LH-W is suitable for pocket or keel mounting in fibreglass hulls only. Pocket- or keel-mounting installs the transducer flush to the hull in a custom pocket, providing minimal drag and good high-speed performance. Boat builders may incorporate this transducer in new hulls, and aftermarket installation is possible by routing a suitable hole and fibreglassing the transducer in place.
