Left side of si "fuzzy"
« on: May 30, 2015, 04:17:15 PM »
This been going on for a few weeks. The screen starts getting fuzzy at 5mph on the left side, then if I switch the engine to idle the left side gets streaky black blogs as pict. This will happen no matter what lake I'm on. I repositioned transduce and have tilted it many different ways.
I dream of things that never were, and ask why not?

Raise your motor up a bit and that might help.  The top 3 feet or so on the left side image is your motor blocking your signal.

The picture was taken in the driveway, so the motor is not in its "normal" position. How do you raise a motor??

Trim or Tilt your motor up. Mine does the same thing. I have to trim my motor more than I thought. Mine did real good in a local clear lake with just 2 people in boat. Last trip with 4 people in boat full of gear, ice, full baitwell, ice etc. I actually had alot of difficulty fine tuning my setup. I wonder if weight and the depth that the boat sits in water affects it.  Even at 6-7 mph, the angle of my boat in the water is slightly different with motor trimmed up. Maybe boat is spraying water or bubbles toward transducer?? I'm still learning...  :P

What was your chart speed, sensitivity and sharpness set at?

Something looks more amiss than just the left side ...

Next time out get screenshots with these ...:

*Bring SI Range in to about 50ft each side ...
*Boat speed and chart speed at about 3 ...
*SI Frequency (try both 455kHz and 800kHz) ...
*Beam Frequency 200kHz ...
*Max Depth under Sonar tab to 20ft below deepest water in your lake ...
*Contrast 10-12 ...
*Sharpness Off  ...
*Noise filter under Sonar tab Off ...

I'll park it on a hill so the motor is in the "normal" position and take another picture. I  automaticly run the motor in ?"max trim" now, so I will try playing with that.
