I am now using a Hummingbird 200 DX. It shows depth and will mark fish. I am wanting to have something that will show small fish like Lake Perch. The fish are in large schools and most of the time I can not tell what is bottom and what are schools of Perch.
I am looking at a Hummingbird Helix 5 Sonar or the Helix 5 Sonar GPS.

Will the Helix 5 sort out the perch sized fish from bottom?

Thanks for any advise.
