i just bought garmin echomap fishfinder and don't understand why looking at screen while boat is not moving the screen still shows moving. anyone experience this or just me? 

Is it moving around circularly or it is moving as if you’re still moving forward? 

Are you in demo mode?

The screen will continue to scroll even if you’re not moving.  The screen isn’t linked to your travel speed (though that would be a cool feature).  What you are seeing is whatever the transducer is pinging on top of.  If you’re in 20’ of water and there is a fish suspended (and not moving) it is going to keep showing that fish as a big long line of fish across the middle of the screen (even though there’s actually only 1 fish).  

it moves like still moving forward. is there a demo mode?

Most FF have a demo mode, but they are not default shipped in that mode.

 

The screen will continue to scroll whether you are moving it not.  The transducer is constantly pinging the bottom of the lake and showing (on the right of the screen) what it sees.  What is scrolling to the left is what it 'saw' a few pings ago.  If you're not moving then it's going to show the same thing right to left but it's going to keep scrolling and pinging.
