Attached are some images from Lake Eufaula Alabama as well as Lake Thollocco on Fort Rucker. Can someone help me figure out what is causing all the clutter in the water column. I've tried adjusting the sensitivity and even isolated the unit to its own battery thinking it was interference but the problem is still there. Its also very prevalent on the down image view also. It's so bad that the whole screen seems washed out.Attachment 406248Attachment 406250

In case it matters, I have dual transducers on the transom of my javelin 17. When I originally contacted hummingbird about the issue they said it could be a faulty transducer so they sent me a new one and told me that I could just keep the original. Since I do not have a Jack Plate I added the second transducer so one looks left of the outboard and the other looks right with 2d and dsi. Contacted them again yesterday they said that it could be because I have an on-board charger so they are sending me a choke cable. This afternoon I disconnected the charger from the battery to eliminate it and still gives the same results. I also killed the engine while moving to be sure it wasn't interference from it

Someone will chime in but I think your settings are off. Did you try and adjust the contrast? Change colors ?

I have tried to adjust sensitivity and contrast. As well as colors. Nothing seems to help. I've taken the sensitivity down to the negative side and the clutter is still there.

Looks like algae bloom to me. You can adjust it a couple of different ways. You can adjust your water column sensitivity or you can reduce your frequency from Mega to 455. I see this allot in the spring. Hope this helps.
I tried 455 and 800, both frequencies have a worse image then the mega. I've been dealing with the issues since I bought the unit new in March I believe it was when the Gen 4 first came out. I've called hummingbird multiple times and finally sent those images to them this morning so I'm waiting to hear back from them. Just seems to me that this unit is too hot and you can't turn it down any

Looks like an algae bloom to me also ...
Can you test on another body of water ...??

I've tested it on 3 different bodies of water. All seem to have the same issue

Is there any chance that it could be interference through my battery disconnect switch? Currently I have one battery that runs the trolling motor the other battery operates the outboard as well as the helix. The positives from both batteries run through the switch, I have a negative on both batteries tied together. When I did my battery charger test yesterday evening one thing I forgot to do was disconnect the charger from the trolling battery so don't know if it could be interference coming through the negative terminal since they're always connected. With the switch set to battery one I should only be pulling current from Battery one and not the trolling battery so just really at a loss so far.

Any common wire connections from electronics power and trolling power can be a source of interference ...Quote:

Test electronics on a separate battery or isolate starting battery from trolling batteries ..

Tomorrow morning my plan is to temporarily bypass the battery switch and separate the ground that the batteries share. Also going to run a new fused power wire from the cranking battery to the helix. Also going to pull the transducer cable and lay it on top of the deck since it is close to the wire harness to the outboard. The fuzziness still showed even after key power was killed to the motor so not really sure if this is just Overkill.

My trolling motor has its own batteries, my starting battery is its own and my electronics have their own. Nothing is cross wired at any point.
Also try without anything else on it the boat.

May be a dumb question but have you tried in simulation mode? Or using an power supply away from your boat in sim mode?
I ended up sending the unit off to Hummingbird and they said it was a bad circuit board. However when in side scan, certain presses of the cursor causes distinct lines to show up on the screen so I'm not sure if that is a unit issue on going or if it's still interference. Another thing I noticed too, When I take the water column sensitivity down to around -2 to clear the screen I get bits and pieces of images where the bottom touches the water column. That looks like miniature sticks or weeds, it last for 50 to75 feet in distance and then goes away. I know this can't be anything on the bottom because I am running the center of the channel. Usually happens when I'm in water over 12ft. I'm just not certain if that is particulate not being filtered out or if it's just a unit problem

I have the same problems with a gen4 they just sent me. To some degree with my gen 3. I believe the new units or transducers or both have issues. Not happy about it at all as my gen 2s were better.
Did a new unit fix this? I have a gen2 and gen4 with this issue.

Honestly, no it didn't it's still doing the same thing. I have a helix 12 Gen 4 that does the exact same thing to. I just deal with it. I've even sent videos to Hummingbird for both units and they tell me that it's not a problem. Regarding the lines, it will always do this whenever you would Press buttons so has to do with something electrically that's interfering with the screen. And I'm guessing that the newer units are just more sensitive to debris in the water such as pollen so I find myself running them at 455 way more than I think I should especially paying the extra money for a mega unit.

[Thanks. Would like to discuss if you still have my number.humminbird is just running me in circles as well. Not sure I'll be able to continue to support these units if there going down hill. I still want to hook the older style transducer to one if I can find one.
