Personally I get a lot more sensitivity on my Lynx than on my Outback with the same FF (Lowrance Hook 5) but different transducers. I don't know if the difference is the transducer or the mount.
I remember taking notes from someone (Alan Fong?) that the transducer is more important than the FF and the ones that come included are not that good.

OK. I think I inserted the correct file.

I had the same issue a while back, and I think the screen goes blank over a certain depth. I was told by Lowrance tech support that I needed to set the depth range that I would be fishing at. I explained that we don’t fish on the west coast at a specific depth the bottom depth is constantly changing. For me the work around was to buy a different FF for ocean use. I still use the Hook in the lakes, and bays.

Great fish, Time of year to start getting more!
