Answer a few simple questions and the finder will point you to the best matching
fish chapters in the onboard ID book. This first version is designed to be accurate and
useful, so it narrows to the right identification group and likely families before you compare
species in the book.
What did you see?
Fish Finder uses the book’s own identification method: first narrow the correct ID group,
then compare family shape, habitat, depth, and distinctive markings in that chapter.
