[shaunv19c]

hi i have recently lashed out and bought a new sounder, i got the furuno fcv-620. been trying to work it out over the last few trips and can't adjust the clutter. the option is there but blanked outand can't be selected. is this a problem or do i need to change a setting somewhere?

The gain dial is also a switch ,push the dial and a screen will come up that says fishing cruising or off ,select off now you are in manual mode and you can play with clutter ,tvm,white line and a host of other features including manual gain adjustment . I hope that is what you are after ,there is a furuno tuning document on the taylors electronics site that you can download that may help you ...matt

It might be a case of transducer placement.

I have a FCV585 and have never found a need to use anything but auto up to about 150m of water.

Had heaps of problems at first until I fitted an adjustable transducer bracket.
