Thanks for replying back to me. You were offline when I responded yesterday.

Did your Humminbird register deeper depths ok previously?

Does this problem occur when at reset, or when moving, or both?

It's a new unit. It only registers to a bepth of 120 feet. Every thing else works fine. I think it just set to 120 feet. I don't know how to change the depth

Try changing the frequency setting - select 455kHz for the best image quality and depth.
