Airmar R509C-LHW Low/High-Wide Chirp 3KW Thru-Hull Mount Depth/Temp No Connector

The Airmar R509C-LHW Low/High-Wide Chirp 3KW Thru-Hull Mount Depth/Temp transducer is purpose-built for serious anglers and boaters who demand crystal-clear sonar imaging across shallow and deep water columns. This high-powered thru-hull transducer delivers the dual-frequency performance needed to locate structure, distinguish bottom composition, and track fish behavior in real time. Whether you're running coastal waters, inland lakes, or offshore grounds, this Airmar unit provides the reliability and sensitivity that professional captains and dedicated recreational anglers trust.

The R509C-LHW operates on low and high frequency bands within a wide chirp bandwidth, maximizing bottom penetration while maintaining fine target resolution—critical for differentiating hard bottom from mud, or distinguishing game fish from baitfish. The 3KW power rating ensures strong signal transmission even in saltwater environments and high-noise conditions. Temperature sensing capability gives you real-time water column data, essential for understanding seasonal fish movement and locating thermocline transitions. The thru-hull mount design offers permanent installation with minimal cabin intrusion, and the connector-free configuration simplifies integration into existing systems.

This transducer is ideal for center console boats, offshore platforms, and larger recreational vessels where power and performance justify permanent thru-hull installation. The depth and temperature outputs pair seamlessly with modern chartplotters and sonar displays from major manufacturers. Installation requires proper thru-hull fitting and stable transducer mounting to ensure beam clarity, so professional installation is recommended for optimal results. At 58 lbs, this unit demands secure mounting and adequate hull reinforcement; consult your boat builder or marine surveyor before installation to verify compatibility with your vessel's hull thickness and construction.
