I can't get it right.shallow water I have a problem with the left side.

The 1st two images issues can be blockage on the left side or very aerated water bubbles blocking the SI pulse ...
The easiest troubleshooting scenario is to remove the xducer from the transom and stick it way down in the water where there no chance of physical blockage ...
*If the image clears up ...then the issue is definitely something on the transom (or bubbles from the transom) ...
*If the issue is still present ... Post back ... Because something in the hardware may be kaput ..

Ok I will try my trolling motor transducer. This was my first time out with the 1199 since I got it back from Humminbird for the 800 kHz washout and new software. I did not have this issue last year but I did move the side to side angle of the transducer to compensate for a kicker motor I just had put on.
-
Hmmm, I was thinking that it was the training wheels on the bicycle. Aren't you a little old for those born 2 fish? ;D
Seriously now: I would see if you get that same left blockage with the boat drifting and motor off. It looks more like bubbles off the transom which would disappear when drifting. It could also be the water intake screen as we have seen those cause some problems but usually not anything that affects the outwards distance of the Si beam (normally just a constant line next to the centerline).
I would also try testing at slower and faster boats speeds just to see if the problem gets better or worse.
Checking your 1199 unit on your 898’s transducer (and your 898 unit on the 1199’s transducer) will tell you where the problem is: unit or transducer/transducer mounting and so is a very good idea.

Thanks Greag I will try to get back out tomorrow or Saturday at the latest I will post my results.
-
After looking it over I'm thinking the left side was getting turbulent water from a row of rivits running down the hull of the boat so I lowered and leveled the SI transducer hopefully it will be in clean water now.I will post a pic later when I get home.
-
That could be b2f. It's hard to tell how low the transducer was from the side pictures.
Something else that may help with this would be to use a thicker transducer mounting board. It could push the transducer backwards and into cleaner (air bubble-free) water. You may have to trim the motor up a little when using the Si sonar though.
-
Im going to double or possibly triple the thickness of the transducer board for the si transducer if this don't work.
-
Please let us know how it turns out.
-
Here is how transducer is now.I will try to test tomorrow if I can.

update after moving the transducer I went out today I took alot of snapshots witch only 2 from the 1199 saved but I did get a few from the 898 using the 1199 transducer the amber is the 1199 the blue is the 898 I think the 898 looks much better Do you think there could be a hardwear problem with the 1199?? I should add this was not a problem last year I sent the 1199 back to H/B in febuary for the 800khz wash out now this
-
There does look to be something amiss with the 1199 unit b2f. With the same transducer and comparable unit settings you should get near identical performance between the 898 and 1199 units.
When you contact the Humminbird Customer Service folks about this, get some of these images to them to show what it is doing and the fact that another Si unit is not doing it.
-
Thank's everyone the 1199 is on it's way back to H/B to be fixed.
-
Just a quick update 1199 went back to H/B they said nothing was wrong i'm still having the issue so this weekend i'm adding another HDSI Transducer on the port side of my boat so i will have a duel HDSI transducer set up one for left & one right if this does not fix it i'm selling it.

Post screenshots from the dual xducer setup so we can compare ...

I will post screen shots next weekend I'm going to install the xducer Saturday and it's going to rain the rest of the weekend so as soon as I can get out I will get the shots
-
The duel SI transducer set up did the trick here are some snap shots from today with the new set up.
-
Awesome b2f ...
The only anomaly I see now is in the 1st shot of occasional sonar blockage ...
But I also notice in that same image that the depth is 3.3ft ... And the structure looks to be weeds ...which could actually be tall enough in that shallow of water to block some the sound pulse ...(creating the very dark horizontal lines) ...
The other shots are fantastic ...
More screenshots please ...

Looks like a great setup ..... No SI blockage, and you should also be getting good high speed 2D.

I thought it could be weeds also but I went to a very clean lake with gravel bottom and I had the same results. I think my issue was air bubbles coming off my rivited hull I'm very happy with it now I will try to get some more screen shots when I go some where that actually has some nice structure to scan. Is it normal to have to turn sensitivity way up when in 100 fow when scanning?

The SI Sensitivity setting criteria is dependent on many variables ...:
*Water Depth
*Waterborne particulate
*Distance to desired echo target
*Bottom composition
*Image frequency choice
I've seen hard gravel bottoms only needing a Sensitivity setting of 1-2 ...
I've seen soft mud bottom needing a Sensitivity setting of 20 (and still needing more) ...
I keep the SI Enhance Menu overlayed onto my SI image anytime I'm viewing SI ...
This gives me instant access to the SI Sensitivity setting as the above mentioned variables change with my boat's movement over different water characteristics/bottom compositions ...

Rickie yes those are weeds blocking the sonar that is a very thick weed bed that goes to the surface with that sand bar in the middle of it. Thanks for al your information and help that goes to BOB & Greag also.
Here are a few more shots from Saturday.
-
Shots are looking good b2f ...
Experiment with other palette choices ...you may find other palettes that work well for your eyes depending on sunny or cloudy days ...
