A remarkable compact hull unit that reliably scans all around the vessel in a specified sector, bearing and tilt angle. The CH-270 is a sophisticated new searchlight sonar designed for small fishing vessels and pleasure craft. Individual fish, fish schools and underwater objects are displayed on a 10.4″ color LCD. The echoes are displayed in 8 or 16 colors according to received echo strength; the strongest echoes are red and 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 optimal day and night viewability. There are eight display modes: full circle scan, zoom, vertical scan, vertical sounder, combination of full or half circle with vertical scan, full circle with history, full circle with strata and full circle with VideoPlotter. In the vertical scan mode, you can view the vertical plane in any direction around the vessel. The CH-270 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 the cross section scan window appears.
