    Default intermittent faulty depth reading

    Here's a silly one. My depth has been mostly good, but all too regularly, and always it seems when it matters most, the depth reading would go from the known and correct to a wildly incorrect figure, say from 3M to 70+! (never a lower than actual reading though it seems)
    Having tried everything obvious over the last six months afloat I have now had it looked at whilst we are out on the hard for a week - only to discover that whoever fitted it managed to do so with the sender slightly recessed into the hull! So very often there has been a bubble of air rolling around in there - enough it seems to create a false reading. I doubt very many sounders will have been installed like this, but if your depth readout is mostly good but occasionally errant then it's one more possibility.
    For the record - I've fitted a new sender close to the original position and will remove the old & fill and fair the hole this winter.

    Mine does that. I will double check when we lift next Monday.
