om...
Guys,

I need to increase my knowledge about fishfinders. Not looking for
"sonar hits the fish results in a dot" but in detailed stuff,
technical things, tips tricks and such .... Stuff like what objects
cause what returns under which circumstances.

I have a Garmin 240 Blue, also am looking for users of this unit.

I couldnt find any really good info on the web, does anybody have any
links or knows about literature?

But maybe there isnt any more to it

Matt

I have a Garmin, not sure what model, but it doesn't matter. Here's the
deal: Fishfinders show you the fish you can't catch. It's like watching
Saturday morning fishing shows that make you say "Awww...sonofabitch! He's
fishing right where I was a week ago and I caught nothing!" Their cone of
coverage is never enough to do any good. The only value of under-the-boat
electronic stuff is simply to show you depth, and help you learn about the
physical structure of the places you like to fish. From there, you go to
books, or people who understand better than you the relationship between
structure and fish habits. Period. There is no free lunch. I don't care WHAT
Tom says.
