Hello BILLFISHER21,

I'm sure the previous poster can confirm, but it sounds to me as if he did a Sounder Reset. The exact menu steps depends on what product you have, but here are examples for recent product software:

LH2: Home > Fishfinder > Menu > Setup > Sounder setup > Sounder reset
LH3: Home > Fishfinder > Menu > Settings (gearbox icon) > Sounder > Reset Sounder

For all recent products I strongly recommend running everything in Auto. I have tried and failed to produce better results in manual sensitivity setup than Auto does. Button-pushing almost always results in worse results rather than better.

There are a couple of exceptions:

• with steep 'cliffs' and drop-offs, in very deep water (for the sounder model) or at high speed when conditions are challenging, Auto Range can sometimes struggle, naturally enough. In these cases using an appropriate manual range can help. Leave everything else in Auto.
• for performance troubleshooting
  

If you do use manual sensitivity, be prepared to be constantly adjusting for changing conditions and boat speed, but do you want to spend your day tuning your fishfinder or in fishing?

If Auto isn't working for you, please read through the Performance troubleshooting guide I linked to above and then post back diagnostic screenshots.

Regards,
Tom
