1198 looses bottom?

[AllenW]

I have the Huminbird 1198 and in shallow water it seems to run well, when I get out on Superior it looses bottom at times.

In 300 fow it'll show from 2 foot and deeper

A call to HB resulted in a suggestion to restore defaults and set depth to a range instead of auto.

Neither cured the problem.

Nothing like having a 130 ft of rigger wire out and looking up and seeing the finder showing 5 foot.

Anybody have this problem or suggestions??

I'll call HB again, but hoping somebody knows how to fix it.

Turns out a bad Wye connector, fwiw.
