I noticed that the transducer was level and not pointed down like my old transducer was.
So I angled it down, still flashing 29.3'.

Any suggestions?
Sonar is to be used in water for proper results. is not a good idea to run the transducer for any length of time while out of water as prolonged use that way could damage the transducer.
