Furuno has announced a free 3.01 software update for NavNet TZtouch3 displays that includes chirp side-scan capability (side-scan transducer required). This feature works at a lower frequency (220 to 240 kHz) than other side-scan sonars, providing the ability to see structure at distances greater than 1,000 feet off each side of the vessel. With the same update, Furuno also brings additional functionality to its personal bathymetric generator within the DFF3D multibeam sonar unit. The new features allow boaters to create shaded-relief charts and store them on their MFDs. The 3.01 software also unlocks compatibility with the soon-to-be-introduced DFF3-UHD High-Power TruEcho CHIRP Fish Finder with 2 or 3 kW power output transmitting across low, medium and high chirp frequencies, or common CW frequencies with max depth scales of 15,000 feet. Download the new software from the Furuno website and check out the additional new features.
