After using one in my imagination for over a year ...I finally picked up an actual LX7 from Radioworld a few weeks ago... I have used it once on the ice and had some difficulty with the dynamic depth at first ... it was bouncing all over and had a few bottom "interruptions" ... I still was able to enjoy it using auto depth or manual depth. Fishing in about 23' ... sensitivity was around 5and marked/caught a few eyes! As soon as I got home I downloaded the newest firmware for the LX7. Followed the online instructions to download and install (well actually my wife made me follow the instructions to the letter after a few failed attempts on my own
) and it installed without issue. They say that this new version will correct difficulties with dynamic depth among other things. I haven't been out since but I am confident that it should correct the problem. My first impressions of the unit ... LOVE IT and can't believe I waited this long! Screen is awesome ... completely adjustable for personal preferences and I finally have an idea of how much bottom I am picking up. Only drawback ... its a bit heavy compared to the old Humminbird but I suppose that's to be expected when you are carrying a flat screen TV on to the ice
This is the link to the firmware and instructions ... best to maintain composure ... and follow the instructions step by step before your wife has to step in and do it
