fishfinder problems

[PerryC]

What Spookey said is right on IMHO. All models are different, but on some if your fish ID is off, they'll show as a mark on the screen, but that's it. The air bladder in the fish is what the ff's see, so if you cruise over a halibut or other fish on the bottom, you may not see them because they may have a smaller bladder than your ff is set to see, and there may not be enough separation between them and the bottom in addition to that. If you got a good strong signal of the bottom, a setting may be off or maybe there just wasen't that many fish above the bottom to register. I know Humminbird has a pretty decent online help for this subject on their website that may help out.

How was the fishing at Cherry?? Inquirey minds want to know...
