I am a new 3d owner and from my first time wherever I go I always see this mountain on my right, this starts to happen after 20m depth while in the shallowest it does not show it, the transducer is thru hull, do you know what could be wrong?
The DFF3D would normally post in the sounder area or under the MFD machine type running the sonar. Your machine appears to be TZT2 or TZT3. The question posted under the NavNet 3D (which is a much older NavNet system) was a bit confusing for a second. It isn't a huge deal but considered off topic for the NN3D system topic area.
