Lowrance downscan noise/snow

Recommended Posts

Just got a Lowrance Elite 7 as my first sonar. I have it mounted on a Scotty arm near the front of my kayak away from my paddle strokes. I really like the unit but I'm unable to get good clear downscan or sidescan images. My guess is that it's a simple setting or mounting issue and hopefully someone can point me in the right direction. I'm running the unit off of a 12v 8ah battery with nothing else connected to it so I don't think electrical noise is the issue. As you can see in the screenshot, I'm getting a lot of "snow" in my image and no crisp lines or images. I tried both 455 and 800khz with similar results. Any suggestions/ideas?

DownImaging should be set to 800 kHz.

Slow down the ping speed some.

Turn the FishID off.

Turn the Surface Clarity filter to LOW.

Is this an Elite CHIRP, TI or HDI?

It is an Elite-7 Ti with Totalscan

Yea, great machine. Do you have TS transducer selected in the sonar installation menu?

Yes, just verified that I do have the Totalscan transducer selected.

OK so you might like to also try the Noise level to LOW.

 

If none of this works for you, I suggest Soft reset...try again...if no love then try Hard reset and redo installation menu selections.

 

Does this look the same on more than on body of water?

I appreciate the suggestions! I will certainly give them a try as soon as I can.

I actually have only tried it on one lake so far, I'll try it on a few others and see what changes.
