Lowrance X4 pro - Lowrance Boating

Greetings,

Please consider returning the device to the manufacturer and purchasing a Garmin GPS from amazon, BestBuy, or Walmart. Garmin has been around for at least 1 decade and I believe has a more solid brand name than Lowrance.

Thank you.

Ebay.com has several broken or used models with an old printed manual.

Example:

your backlight is defect, or check brightness

Check if transducer is connected properly.

bad transducer or bottom lock is out

go in your unit on menu go to simulator click off

solid vertical lines on graph different widths...is this the transducer?

Here is a link for you
