I'm having trouble with getting fish arches to show up. There's a fish Id function but it's not optimal. I believe it's a settings problem but I could be wrong. I'm just running it on auto currently. So if you have any tips or manual settings that I could try out. Any help would be greatly appreciated.

what exactly are you getting, nothing at all, or not your protypical "arch"

is it reading bottom correctly?

It seems to be reading the bottom correctly. Yes I don't see any arches. I'll be catching fish though.

In that case usually if you adjust the sensitivity option in the sonar settings it will fix this problem.  I would start by turning the sensitivity all the way up to max or 100 percent and then back it off till the screen clears up a lot and majority of the clutter goes away.  If you have to do a total reset on the unit to restore factory settings hold the plus minus and power at the same time this will restart the unit.

Ok thanks. I'll give it a try on Monday when I take the boat out.

Also, understand to see "arches" you typically need to be idling, or a fish must quickly swim through the sonar cone.  When you are fishing and moving slowly on the trolling motor, fish will be more "lines" than arches because they are in the sonar cone longer when compared to idling with the outboard and pushing the fish through the sonar cone quickly.  In addition, when you see an arch, that fish is already behind the boat, outside of your sonar cone.  When fish are in the cone, you will continually get a return (hence the "lines").
