The Furuno CH270BB Sonar is a new sophisticated searchlight sonar designed for small fishing vessels or pleasure craft. Individual fish, fish schools and underwater objects are displayed on Display supplied additionally. The echograms are displayed in 8 or 16 colors according to received echo strength; the strongest echoes are red, the weakest are blue. One echo can be displayed in white so that a specific echo level is highlighted. The background color is also selectable for optimum viewing day or night. Furuno CH270BB Sonar Cross Section Scan Example: See our Furuno CH270BB Sonar HD Video on Youtube.com The Furuno CH270BB Sonar consists of a separately supplied display unit, transceiver unit and low-profile hull unit. This 3-unit configuration provides a space saving installation. A Black Box configuration (without monitor) is also available. The hull unit will fit any boat where a 147 mm (6) hull tube is available. Also, previously installed CH18 or 28's can be upgraded to a Furuno CH270BB Sonar without dry-docking since the hull unit is the same. Furuno CH270BB Sonar Display Modes: There are eight display modes: full circle scan, zoom, vertical scan, vertical sounder, the combination of full or half circle with vertical scan, full circle with history, full circle with strata and full circle with Video Plotter. In the vertical scan mode, you can view the vertical plane in any direction around the vessel. The Furuno CH270BB Sonar features a unique Cross Section Scan to view the vertical plane. When you find a specific echo in the full circle scan mode, just push the appropriate CUSTOM MODE BUTTON and then the cross section scan window appears. The Furuno CH270BB Sonar provides two modes to track a targeted echo: target lock mode and L/L mode. The target lock mode permits automatic tracking of targeted fish schools within a predetermined search zone after it has been manually acquired. In the L/L mode, the beam is locked to the position (such as a fish shelter or reef) chosen with the target marker. This mode can be enhanced with more accurate position input such as DGPS or WAAS.
