fvc-627

[Anonymous]

I recently bought a new boat w/furuno electronics my fvc-627 w/airmar p66 transducer..Well I cant get it to stay on I mean as soon as I start moving it starts going haywire takes for ever to reaquire images or the screen changes completely "any help is good help" the picture they show it on the web site looks great all that blue water with the beautiful bottom structure YA how do I get that and should it stay or at least continue to show a depth at a cruising speed........One more ? is it ok to fiddle around with the fish-finder when out of the water ?? the transducer is 600wt I believe.

Bythesea,
If the sounder reads OK at the dock but as soon as you start moving the performance degrades it is most likely turbulence going over the face of the transducer. A P-66 being a transom mount is very susceptible to this. One way to tell is to look at both frequencies (50 & 200Khz). If it is turbulence, you will start to see noise and gaps in the bottom on the 50Khz side first as you speed increases. Is to possible to post a screen shot of both frequencies and how your transducer is mounted?
