Question about Garmin Fishfinder 160 GPS Receiver
Change your setting from saltwater to fresh water even if you fish in sea water,your transducer is a 00/200KHZ and not a 50/200KHZ.

If you can drop it even a little further to about an inch below hull line and try it, that would be a good test. I guess the only other thing to check is that the transducer is close to horizontal in its positioning, and then check your gain/sensitivity settings. Try remove the settings from any auto modes they may be set on and manually set gain/sensitivity to a higher value. Often when you set a fishfinder to Auto mode you automatically lose up to 30% of the raw data that comes from the transducer!
If all of the above have been done and still no success it might be worth contacting Garmin or sourcing a replacement unit/transducer. That is about all I can think of at this stage.
