Hello all,
The other day I was out using my marcum vx-1 pro that I got about 3 years ago. It was doing fine then all of a sudden stopped displaying any marks. The screen showed a solid red thick mark right at O but nothing else. Previous times using I never had problems. Also I thought I could recall hearing like a humming noise from the transducer when it worked properly in the past. Now there is no humming noise coming from the transducer. Any suggestions?
