CVS-FX1 12.1-inch Color LCD Echo Sounder
Ultimate broadband sounder with digital processing

Four selectable frequencies  This innovative sounder is equipped with the capability of selecting optional four frequencies within the range of broadband transducer (two types available: TDM-052 38kHz to 75kHz / 130kHz to 210kHz and TDM-062 38kHz to 75kHz / 85kHz to 135kHz). This feature provides its user with the possibility of fine tuning for spotting desired types of fish, improved search of water depth. Flexible selection of frequencies by 0.1kHz step enables the user to stay away from interference with the sounders on the other vessels.
Condition Memory  Up to six settings can be stored in the Condition Memory (CM). The user can recall each setting quickly by simply pushing the CM keys.
Image storage  Stores up to 500 screen images in built-in memory to recall the images later by a single touch.
Good visibility under sunlight  High quality 12.1-inch XGA display is adopted. The LCD and acrylic sheet with Anti-Reflection coated filter are bonded directly. It increases visibility in direct sunlight and prevents condensation.
CCD camera input*  Connection with owner supplied CCD camera and with external monitor is available to offer more convenience for comprehensive graphic presentation.
