Furuno's DFF1-UHD sounder module debuts the company's TruEcho CHIRP technology, which operates across a range of frequencies (50 kHz plus/minus 20 kHz, 200 kHz plus/minus 25 kHz) to deliver better signal clarity, resolution and target definition. The module also offers two new features: Bottom Discrimination and Accu-Fish. With Bottom Discrimination, anglers see information about bottom consistency, whether rock, sand, gravel or mud. Accu‑Fish assesses the approximate size of a fish below the boat and displays it graphically. The DFF1-UHD connects to NavNet TZtouch and NavNet 3-D MFDs or to a NavNet-supported Ethernet network. Suggested retail price is $1,995. Call 360-834-9300 or visit furunousa.com.
