thanks for the link. I guess i need to play with the settings more and see what i get. i know these units don't actually "find fish". I am just not sure that i am getting an accurate picture of what is below the boat.

it seems like i am consistently getting a flat bottom with some depth changes, i am not seeing things like trees and cover that i know are there.

but i will reread that post you linked a few more times and try to adjust the settings accordingly.

thanks,
michael
