Control unit

The User Program Control provides for instantsetup of the equipment according to fishing ground or target fish. Ten programs may be set up, andvertical and horizontal display settings may be programmed together or individually. In addition, there are Function Keys at the bottomrow of the control unit that let you assign up to 10 frequently used functions to them.


To enhance operator usability, a sub control unit anda wired remote controller are optionally available. Additionally, the FSV-85 also allows the operatorto use a USB wireless mouse.



Dual Monitors For Increased Productivity

The FSV-35/85 has an ability to use a dual monitor setup to extend your sonar display across two screens. Comparing horizontal and vertical modes is easier when you have dual monitors. You can show two display modes, comparing horizontal and vertical section side by side in separate full-size windows, for example.

FURUNO provides displays in a number of different sizes to suit any need.
