Lowrance LMS 520c Fish finder shuts down

SOURCE: How do you get the fish to show up on the screen

Are you looking for the little fish symbols?
Press MENU, down arrow to SONAR FEATURES and press ENT. Arrow to FISH SYMBOLS and press ENT. Press EXIT twice. Any significant return in the water will now show up as a fish symbol.

Are you looking for the fish arches?
You won't get any arches unless the boat is moving and of course there are fish passing within the transducers signal. The shallower the water, the less area you are covering and less likely to get a fish return.

There is an OK guide to understanding what you see on the sonar screen at the link below. It if pretty technical but parts of it may help you out.

If your problem happens mostly in weedy area's, you should try downloading the latest version of software from the lowrance site. It's Ver 2.5.0. You also need to change your fishing mode to "shallow water". I experienced the problem as described on the site, and the download fixed it.

Hope this helps you.
