High-Performance Chirp-Ready Transducer for Superior Marine Navigation

The Furuno R109LH Transducer is a powerful, externally mounted transducer designed for serious offshore anglers and commercial fishermen. With its advanced Chirp-ready technology and high-power output, this transducer delivers exceptional target resolution, precise bottom discrimination, and superior bait and game-fish separation. Equipped with a robust urethane housing and fairing, it ensures optimal performance even in demanding marine conditions.

Dual-Frequency Precision for Enhanced Detection

Operating at both low and high frequencies, the R109LH provides broad bandwidth coverage, making it an ideal choice for deep-sea fishing and bottom tracking. Its low-frequency range of 38 to 75 kHz allows for exceptional depth penetration, reaching up to 1,829 meters (6,000 feet). The high-frequency range of 130 to 210 kHz delivers crisp details, with an 8° to 4° beamwidth, ensuring precise fish-target discrimination and bottom contour clarity at depths of up to 457 meters (1,500 feet).
