Default 1242xsv touch w/GT51TM

Not sure but something doesnít seem right with image? I havenít gone out to deeper water to see but this is from my canal and also in my slip. The Sideview image keeps zooming in and out and only shows blue image. The others show a very blurry bottom as opposed to sharp image. Also depth shows negative but it reality was about 4-5í of bottom under boat?
Any thoughts on what it could be causing this?

Were you underway or just sitting there?

Iím wondering if the transducer is connected properly. I would check the connections and be sure all of the frequencies are set to default to start. I have never seen one show negative.

For starters I would take it off of manual range. Looks like its showing 2.9ft deep on the image but not in the top left corner. Mine acts weird in very shallow water. Get out in 10ft or more and try again. Make sure everything is in Auto.

Check the keel offset. If it is set deep it is going to show a negative in shallow water.

Is this a rorschach test? I see a walrus and a cat in the first pic.

That was one of my concerns. For some reason it seems like a distorted image versus a sharp/crisp image. I guess before I can trouble shoot or think something is wrong I have to get boat into deeper water. I only was able to get boat ramp and go few hundred yards to my slip. I donít think I went deeper than 6 feet during that ride. I just donít ever remember any of my images like that. Iíll probably get boat out this week.

If you are talking about the orange section, that's bottom,. I was being facetious. The dark area above is the water column. Don't worry about the orange section, though it can tell you if it's hard or sandy. The arches down there in other pictures may be fish very close to the bottom in deppressions smaller than your cone angle covers, so they appear to be below the bottom in some places.

The first ppicture is normal for water with nothing in it.

yes I was talking about the orange part. But understand it wasnít very deep. I doubt there was any fish there just yet. What has me concerned was the Sideview image which I canít post cause I took a video of it. But it kept zooming in and out and never showed any bottom just blue lines on both sides of center.
I guess Iím beating a dead horse until I can get out too deeper water and see if it all self corrects. Maybe for some reason settings were changed from last season? I removed unit over winter and had it in my house.
Thanks

Yeah somethings hosed up. Even your first pictures of the bottom don't look right to me. The bottom looks very weird. I have the same transducer and a 1042xsv non touch.

Did it work perfectly before or has it always looked like this.

There are two different modes shown below. The second picture is clear vu, and the bottom is totally normal for that image at that depth. The third is traditional chirp as is the first.

The orange/red is bottom, and you shouldn't concerned. Note that clear vu is very good at picking up structure, but not so good at fish. Traditional chirp is good at fish but not detailed structure (like boats or brush). Different tech for different uses.

Ignore the area below the bottom line.

worked perfectly before. Pulled boat in December and everything was fine. Put boat in two weeks ago and this is what it shows.
Transducer mounted lowest point center of keel. Nothing changed from the fall.

I get the orange/red bottom as itís the creek getting to my boat and itís very soft and muddy but what concerns me is the image of Sideview bouncing back and forth. Itís on Auto and when I adjust with a range it switches automatically back to auto.
