Perch or Crappie on fish finder?
I have a lowrance elite 3x (only sonar) and the last few trips on my kayak have been a lot of fish finder practice. Is there any kind of hints whether or not what I'm seeing on my finder is perch or crappie? I mostly have been looking for a good school of fish on the finder then catching 1 or 2 to see if I guessed right but haven't really nailed down anything specific.
I think I've noticed perch show up as a massive blob on my screen (I figure its because they move so fast) and crappie seem to be a little more spread out and each fish more defined (they move slower?)
Also, if I'm on my kayak, should I set my ping speed to be slow when I'm just paddling slow? My idea is fish that are moving very quickly with my ping speed set the fastest wont really show each fish since their moving so fast.
Thanks everyone in advance.
