We are confident that you will enjoy many years of operation with this fine piece of equipment. The KF-667 is just one of the many ONWA developments in the field of echo sounding. The compact, lightweight but rugged unit is easy to install and operate and is suitable for both fresh and saltwater applications. This unit is designed and constructed to withstand the rigors of the marine environment. However, to obtain optimum performance from this unit, you should carefully read and follow the recommended procedures for operation and maintenance. No machine can perform to the utmost of its ability unless it is installed, operated and maintained properly We would appreciate feedback from you, the end-user,about whether we are achieving our purposes. Thank you for considering and purchasing ONWA equipment. Features The KF-667 dual-frequency(50KHz and 200KHz)color video sounder has a large variety of functions, all contained in a splash-proof rugged plastic case that is compact to fit small boats. The principal features of the KF-667 are User-friendly design for simplified operation. A wide variety of display modes: bottom-lock expansion, marker zoom and unique bottom zoom displays. Potent 300 W transceiver. 8-color presentation(including background) on a 5.6 diagonal TFT LCD, providing vivid presentation of underwater conditions. AUTO function permits unattended range and gain setting operations. The range scale and gain change automatically so that the bottom is displayed in reddish brown or red on the lower half of the screen. A-scope display gives excellent bottom fish discrimination, vital for bottom trawler and lobster/crab potter. Digital and analog displays of navigational data. Alarms: fish, bottom, water temperature (requires appropriate sensor). Six pulse lengths for excellent performance on both shallow and deep ranges. Universal 12-24 VDC power supply drawing 30 W of power at maximum. Water temperature sensor optionally available. PRINCIPLE OF OPERATION This Color Video Sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on a 5.6-inch color screen. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source. Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflect...
