Description

The SI-TEX BT87M1KW18 is a bronze low-profile thru-hull CHIRP transducer engineered for high-performance fish finding and bottom tracking applications. Operating across the medium-frequency 85-135kHz CHIRP range with 1kW output power, it delivers strong target separation, detailed bottom definition, and excellent shallow-water performance. The 18-degree tilted element is optimized for vessels with higher hull deadrise angles. || The low-profile housing minimizes drag while supporting high-speed operation. Integrated temperature sensing provides additional environmental data, while the narrow beam pattern helps identify fish holding close to reefs, wrecks, and underwater structure. || Constructed from bronze for durability in marine environments, the transducer features an 8-pin connector, 26-foot cable, and thru-hull mounting design. It is ideal for offshore anglers and serious boaters seeking enhanced sonar performance and reliable CHIRP technology.
