Hello..
After 1 month I went to my boat... (My boat is in the sea and also transducer is submerged into watter)...
I noticed that something is not working well..
Classic sonar view gives me strange image (like there is no enough power ?!)
After 3-4 hours on the sea also the side scan wan't to work well..
The questio is why is this happening?
1.) Bad battery power (I know that my battery is not ok.. I must change it with new one because it was not full filed for more than one year and also if I turn off the engine the voltage come down from 13.4V to 11V very quick)..
The 14-15V as you can see from picture is from my Yamaha F-80 engine..
2.) Transducer problem? (is there a possibility that watter enter into the transducer?). Is there a way to chek up the transducer with some instrument? (ohm mether)
Here are some screen shoot-s (I have cheked the transducer so its in the line with the boat hull)
also the recorder log is "strange"...
