As you can see my gains on the Livescope images are now in the 40's. Previous to the updates I typically Dan closer to 60. Last year the time I did not have the issue with pollen and excess clutter like I do now. Now I'm getting dead zones that wipe out everything in that part of the beam. My bait, fish, and even parts of the brushpile. Not good, not acceptable!
Have you tried resetting it to factory settings after the update? Just a thought.
