Okay I'm new to sonars. So don't judge plz. I got a humminbird helix 5 si g2. I got the side and down imaging pretty much figured out. I'm only a little confused with the 2d sonar. I understand chirp and how it works. And the cones and all that good stuff. I'm just a little confused which is best for locating bass and baitfish.? From my understanding it has 3 settings to choose from when picking a frequency. Medium which I assume is 83khz. Then there is high which I assume is 200khz. And lastly there is medium/high which I assume is 83/200khz with the dual beam? Correct me if I'm wrong please. Which is best to use for locating bass and baitfish? Thanks! I only fish tva lakes btw. So no super deep fishing. 40' at the most and that's pushing it

I really hope it isn't a software problem. Ima try lowering it. I wish I could post a pic ok here to show y'all what I'm seeing on my screen. If that doesn't work then I guess Ima contact humminbird support

Okay thanks. I will try that. Doesn't the transducer have to be lined up with the bottom of the transom? That's how I have it. I'll try lowering it and see if that helps!

Sorry. Transducer is located on transom. Starboard side. I've got another depth finder on trolling motor. Yes I've tried it with everything else turned off. Like I said, when I pick up a little speed(bout 5mph) it goes away. If I'm sittin still or going rlly rlly slow the lines are present. Idk if it's some kind of turbulance or what? I tried adjusting it and nothing I would upload a pic from my phone but it says the file is to big ? Sorry for my noobness

Help! Can not figure it out! And it wont let me upload a pic on here so I'll try to deceive it! On my humminbird helix 5 si g2 when I am going very slow 2-4mph there is white lines streaking on the screen. If I'm in side imaging the white lines are vertical down the left side, right beside the boat in the water column. If I'm in down imaging the streaks are horizontal near the top of the screen. It will also do this if I'm sittin still. Not motor started or anything. I go 5mph to scan areas and it goes away. But still aggravated!! Please help
