What to do with my fishing buddy.

[DKSRenegade]

I have a 2250 with side finder. I don't use the side finder much because it only locates fish at the depth that the probe in located in the water 2' to3' deep. I think the fish that show up on the regular screen show size of fish and the depth they are at. The problem is that I catch a lot of fish that never show up on the screen.I don't know to use the filter or range controls. If I learn how they work, then I may like the unit better. I got it used without instructions.If you have any info that will help me better use the unit please let me know. Thanks DKS
