Ok so I need some help! I have a piranha max 197c di Fishfinder unit. It's both sonar and downscan. Ive been out on the water a few times with it and am seeing fish on the unit, but I'm having problems determining what's crappie and what's not. Could someone please share a few images of wintertime crappie on their Fishfinder. I just want to have a general idea on what I'm looking for. Thanks!
