Just installed the unit yesterday and out on the lake now. Picking up some weird signatures that I don’t pick up with my 535. I set the sensitivity down to 4 and still shows up strong. It only shows when I’m in roughly 28+ ft. Max depth at this lake is 50 ft…
What lake is this and what species of fish and bait are present? At this time of year some species of gamefish and baitfish school up, but from the looks of it the screen shows the marks stacked up from 33ft to 20ft of water, which would be a HUGE school of fish.
Does not match the DI…
Is the DI working?
Either 2D or DI is lying to ya. You need to isolate which.

Yes DI is working, when I’m in 15 fow, i can see fallen wood just fine. If I turn the sensitivity way up on the DI, it’ll be completely filled with noise/colored pixels.
Also, when I’m in approximately 20 fow, there’s no interference on the screen. It looks clean.
Riddle me this… these pictures are on the same lake and different parts of the deeper(25+ fow) area.
I think it is working just fine. and those marks are schools of fish I would say. the DI is not the same cone angle as the 2D. on my 1198 and 798 I can mark fish on the 200/83 setting and not see any on the DI sometimes. does not look like interference one bit to me
small fish on the DI will just me tiny white specs sometimes if you can see them at all with a large school of bait
That’s a lot of fish then.
How do you explain the straight lines at a 45 degree angle on image 1 and the big cone cloud in image 2?
Try sending these photos to Humminbird and see what they say. Be sure to give them details for settings and water clarity. I have occasionally seen my stepdad’s screen look like someone spilled red yellow and blue ink on it when bug hatches were happening.
DI is junk, worthless, should be ignored.
Your 2d looks fine.
SI will greatly help you identify what’s happening on your 2d. A boat flying by creates cavitation, visible in your 2d, visible in you SI. Looks like there christmas tree in your photo. Bug hatches, bait clouds, zooplankton, etc all show up as blobs and are better identified on SI. Thermoclines show up when present on both SI/2d. If i’m ever wondering what i’m seeing on my 2d i look at SI.
I’ve had my DI views turned off for the better part of 3 years and never missed it a bit. SHould’ve gotten the SI model.
BTW, turn off your GPS COORDS before you post on the internet…if you care.
Thanks for the insight, I do have SI, it just wasn’t showing me anything either. Clean image other than a good bottom structure view. Nothing to show there, but I figured DI should match the 2d.
No boats were flying by, only about 5 boats out that day and they were all in the shallows.
I just can’t believe that there are that many fish all over the deep area. I’m going to boat around on another lake and compare, but I was just hoping someone had a quick fix before going out there again.
Btw, I don’t mind the gps being out there. I only go to this lake because it’s the closest one.
My preliminary conclusion – http://www.biggeorgiaspots.com/otherstuff/204-the-dreaded-fall-turnover.html
Lake turnover rising gas bubbles.
Makes a whole lot of sense to me. My only confusion now is the christmas tree and stacked fish arches. If they’re fish, i’m definitely going back there! I wasn’t fully prepared to fish since I just wanted to test the install.
Btw, I mounted the transducer per the instructions on a bass boat and have no problem tracking depths up to 45mph. Not sure what people are talking about when they post issues with their transom mounted transducers.
not sure about the big cone, maybe submerged log you drove over? those lines at a 45 are small baitfish. alewives look like that here where I live. your 2d looks good to me. you can kind of see the little white dots on your di. those are fish. di works way better in shallow than 2d. most of the time I have 2d a di split on my screen. you can adjust the angle slightly of the ducer and you will get a better arch going slower
here are some pics from mine
Looks like the 2d sensitivity is high. Try clear mode version max mode. You are going to have to mess with the setting some.

I hadn’t read the manual straight through yet, I was just playing with the settings. It looked like the only difference between clear and max modes were that max mode had the gain bumped way high – ie, if I set it to clear, and turn the sensitivity way up, it’d look the same as max mode.
In any case, the sensitivity on there was only set to 6 out of…20?
Finally got a chance to get out on the same lake tonight. It seems that the problem is still there…Since some of you wanted to see SI alongside the 2d, I’ve attached some here.
All these pictures are in clear mode, sensitivity on 7/20
Pic 1 – the line towards the middle on the SI is my swim ladder at 455khz, it doesn’t show up on 800khz since 800 doesn’t have the full 180 degree coverage.
Vertical lines again, some stuff on the bottom but nothing shows up on SI except for light graininess.
Pic 2 – I saw the SI and I’m thinking “oh yeah…picking up stuff on SI finally” but I compared the 2d with the SI and it doesn’t match right at all. If those were fish hugging the bottom, I should see the fish towards the bottom contour with shadows right?
Pic 3 – more stuff showing up but again, no si shadow.
Pic 4 – Don’t know what is up with the christmas tree stuff….
Pic 5 -Looks like fish again but no shadow. Seeing some angled lines in SI too.
Pic 6 – DI looks like baitfish, but it’s mixed in with the angled lines next to bigger arches around the 24.8ft line. If DI can see baitfish, it should see the giant fish arches too, no?
Pic 7 – just a giant arch with no matching si.
I forgot to capture a screenshot, but I tried SI near the boat launch and saw nothing. It looked just like the rest of these pictures. Went alongside some grass along the shoreline and the si image was the same as the others as well.
My conclusion…something is up with the transducer or head unit.
In just about every picture you posted of your 2D shows the same on your SI. Have to remember what shows on your 2D is directly under the boat. if you look there you will see it. You will not see shadows of what is on your 2D, the fish need to be off to the side. What settings are you running your SI?
I run a blue screen for my SI the fish will show up as white much easier to pic them out. I have my SI enhance menu up all the time and make frequent adjustments as bottom and depth change, I don`t care about a pretty picture of structure if there are no fish present so I usually am running max mode in SI. One of the best things a friend told me was WHO CARES IF THAT IS A LOG OR WHAT EVER GET IN THE HABIT OF LOOKING FOR FISH AND FORGET THE REST. Once fish are found then go back and take a better look at the structure. That is what I was doing was staring at the screen trying to figure out what structure I was looking at instead of just looking for fish. It made a huge difference for me.
You will get the hang of it.
Edited to add it looks like you si sensitivity is way high every thing is to bright and washed out in most of the pics.
everything looks right on your unit. you can turn sensitivity and contrast up on your SI, also I see best with blue as well. you have to take into account for water depth on the SI too. at 30 fow and your si set at 55 ft your seeing 25ft of the bottom on each side
Go to the view where you have split screen with
83HZ on left and 200HZ on right
and see if the images are similar
or quite different
If they are different you may want to use
the better quality capture as your choice.
This may be different depending on depths.
I set up one of my favorites for this view
and quite often one is far better than the either.
If you see the same fish on both
get ready to set the hook.
