I have a Lowrance HDS8 that I would like to sell. The unit does not read depth all the time, it will read depth if you reset it and it will work all day most of the time. The GPS works fine, no issues with that at all. Someone might be able to fix it or get it fixed, I don't know. It will not have a transducer with it or an SD card. Is it worth 100.00? Can send pics if interested. I have manuals that go along with it.
