Echonautics BT87H1KW 130-210kHz 1kW High CHIRP 18° Tilted Element
Model: BT87H1KW-18- Superior shallow-water performance and bottom detail
The Echonautics BT87H1kW is a low-profile thru hull CHIRP transducer designed to minimize drag and to perform at high speeds.
Thanks to the narrow beamwidth, it is excellent for pinpointing fish holding tight to reefs, wrecks, and other structures.
