Marcum LX7 firmware 3.17 is up for download
Go to their site download the file to perform the upgrade. You will need a USB cable and please read all instructions fully before doing so.
This new version (3.17) will update your LX-7 to include all the sonar performance developed for the 2013 Digital Sonar Systems. Sensitivity/Gain adjustments have been added for more low end adjustability. More low end settings will allow for more micro adjustments, and improve performance of the Automatic & Dynamic range settings. For owners upgrading from version 2.9 or lower this update will bring in the chart zoom view mode. Note that there are two different files for download below. Make sure you select the correct upgrade file based on the version your system is currently running.
– There is no upgrade yet seen for the LX6 or LX9, hopefully those get posted today also to ease LX6/9 owners.
– Please post your reviews if you get a chance to use the new update on the ice this week.
