Hey everyone,

nned help with my sounder, cant get a readind (good bottom reading) after about 85 metres I have gain turned to 15 after that too much blue comes up on the screen, So when I turn threshold up no info comes back from the bottom, I was at the rotto wrecks the other day and all I could see were three little lumps not what I would expect at all. Ant help would be great...

thanks

Rob
