How do I get the arch shape on screen for fish? I just have small straight lines. It will show balls of bait fish. I keep playing with setting and get things all jacked up and have to reset to factory.

The arch shape comes from having the transducer at just the perfect angle and those little fish have to be in the sweet spot of the transducers cone angle. If you are using a shoot through the hull transducer then you will never have those perfect arches. Well, you might get lucky; but most likely you won't.


Those straight lines mean the same thing as those pretty arches, question is though... Do you know what the different colors of those lines mean?

No one is on transom and other is on trolling motor. Yes I catch fish off those little lines. I just like arches better

You going to have to adjust the tilt of the transom ducer then until you find the right speed and are able to get the arches. Most likely will never get at arches from the trolling motor. It's nothing to do with settings, except 200 gives a bit better image due to its narrower cone angle so it might arch a tad better.

I bet that's it. Shortly after I got the boat I found the transducer tilted all the way down after I loaded up and just eyeballed it back level and tightened it.

Adjusted and took it out. That fixed it. Thanks
