I seem to be getting a lot of interference or noise on the downscan from about 0-15 feet of water.  All the settings I see are for the Sonar, not the downscan.  Anyone know how to get rid of this?

Please post a screenshot of the interference and a pic of your LSS transducer mount.  Your problem could be electrical interference, surface clutter, or beam kickback related to your ducer mount, but can't help further without pics.

Does water clarity have anything to do with the quality of the image?  The wind was blowing and the water was dingy.  I'll get you a screen shot and a pic of the 'ducer when I can.

 

 

Is the "interference" with the trolling motor on or off?

 

Yes wind and current can stir things up and cause the sonar pic to look speckles.

I had alot of surface clutter on my unit as well until I played with the sensitivity.  I have it set at 50 (may be a little higher, can't remember) but it was at 80.

There is no sensitivety adjustment on down and side scan, only on 2d.
