I don't seem to be having the greatest luck with this unit so far. When I use the sonar I have a bunch of small dots or small vertical lines all over the screen. If I set it on fish I.D it clears up. I also don't get any arches on it also. I have the 2.3 version on it and everything is set as it was when I got it. Anyone have any suggestion? I am a beginer at using this type of sonar/gps. I have the transducer mounted in the same spot my x37 was mounted. I have been trying setting the surface clutter higher and noise rejection higher but then it seems like it doesn't show the bottom very well or much detail.

try restting unit back to default settings....tinkering with it you might have done somethin......
another thing depending on what kinda water you are on...
Im in the keys and my boat is in a canal ocean side.....and if you have alot of muck at your dock you will get lines..
test out unit in clear deeper water....... set it up there.... see what happens
........another thing if you have a aluminum boat check your wire to the transducer.......and any excess wire zip tie it up and away from electronics.......

Return everything to the factory defaults and set your Ping Speed to 100, Sensitivity to 93, Chart Speed to 100, and Colorline to 60. You should see clutter (small blue dots - a lot of them) when running. Fish will show up as a small red or yellow dot(s) when you're running. When you're trolling or searching at lower speed fish will show up as larger red marks with some yellow in them. Don't mess with the noise reduction and definitely don't use the Fish ID. That's just fluff for guys that can't get their unit setup right. "Doc" Bruce Samson has some good information on his website on how to setup your unit. If you're in the Detroit / Flint area Lance Valentine holds an all day button pushing class using the exact unit (Lowrance 520C) you own. I think you can buy a DVD from his website.
Once you get the unit setup right it a very useful tool. I'm sure a lot of guys don't know how to use their Sonar / GPS to get the full advantage out of it. It's a lot more than a $650 depth finder.
