dairyman Posted May 20, 2008 Share Posted May 20, 2008 I have an older humminbird--#400---where can I find an oprators manual for it --it works but I don't really know what all the functions are--all I'm seeing are the depth and range. Can it do anything elsethanks Link to comment Share on other sites More sharing options...
Bob/Mn Posted May 21, 2008 Share Posted May 21, 2008 Try Hummingbirds web site. Most manufactures have manuals that can be downloaded. Link to comment Share on other sites More sharing options...
