Fu­runo of­fers a ver­sion of live sonar for recre­ational fish­ing in its DFF3D sys­tem, but this func­tion dif­fers sig­nif­i­cantly from the Garmin LiveScope and Lowrance Livesight. The cross-sec­tion real-time sonar — one of many func­tions in the sys­tem — sweeps side to side rather than fore and aft, and it op­er­ates at 165 khz for a range of 400 to 500 feet. Net­worked with Fu­runo’s Navnet Tz­touch and Tz­touch2 MFDS, the DFF-3D trans­ducer sweeps 120 de­grees in 3-de­gree in­cre­ments with an 11-de­gree fore-and-aft beam width. A rate and mo­tion sen­sor com­pen­sates for boat move­ments to sta­bi­lize the im­age. The cross-sec­tion real-time sonar func­tion is de­signed for find­ing fish di­rectly be­low and on both sides of the boat. Fu­runo’s DFF-3D, in­clud­ing trans­ducer and black-box mod­ule, sells for $1,695.
