Lowrance elite 7 hdi playing up

[Busy-livin]

G'day all

I'm having a slight issue with my sounder

On Sunday morning I was heading out to the peak in the wind and I was cruising at a good speed but I hit a lumpy wave half way out and my sounder instantly played up. Shallow alarm set to 1.0 m was going off and screen was showing nothing but sand and saying 0.7 depth. GPS was fine though This has happened before but I turned it on and off and it was fine but I couldn't resolve the issue this time. I checked the plugs were in securely and that transducer was positioned correct and clear and turned on and off a few times and it was still playing up. And the whole trip in it was buggered.

Any ideas?

Should I have turned the batteries off and on to sorta reset it? I have them off now as it's stored so I hope on the weekend I start her up and she's fine.

Cheers jake
