Need help from someone who knows what they are doing!

Can anyone tell me what I am looking at on ths screen? I would get this every once in a while for a mile or two and then it goes away.

Thanks for the help

It might be the thermocline but its wierd that it is, or appears to be, right at the half depth mark. Your not alone though as I get this on my screen also.

Tight lines,

Looks like one of your down rigger balls to me.. I would guess that because of current, direction or speed, the blow back is chaning and thus the intermitent nature of what you are seeing..

Exactly what my probe looks like. Sometimes in & sometimes out of the transducer cone. Bring your rigger up (or down) while watching the screen to confirm.

Boy you got the right guy for this ,that my friend is a fishfinder.Looks like a thermol layer a temp probe would of confirmed it ive seen it many time over the years probly due to a goofy current in that part of the lake.next trip it probly will be gone

Could be fleas or plankton. I get it on my Humminbird too. It isn't the riggers because it's usually way above where they are.

Looks like the rigger ball to me? Were you running a rigger @ 35 ft or so? Usually I pick up my rigger balls 5-10 ft from where my counter is at, due to blow back,etc. With certain conditions, sometimes you'll only pick them up trolling certain directions. Your gps speed is only 2.2, seems a little slow and that would account for you picking up the ball. Here is a pic of my ff Rick, the green lines are the rigger balls, sometimes I hardly pick them up at all....lots of conditions will play a factor in picking them up.

The red ball is bait

Yea Rod,

It’s got to be the ball.

I try to keep the down speed around 2.0 and that’s why I get it sometimes and sometimes I don’t.

I will move the ball next time I see it and that should tell me.

Thanks

Rick - Did you make it out? What's the verdict?

Yes Tom,

Just got back and it is not the ball.

We watched close and can't figure it out. Trolled a few miles on Saturday and it would come and go. Sometimes it would be at 30 ft down, then stop and shoh up something like 15, then back to 30 then gone for a long time, then back. It would do it at 70 fow and out to 110. It didn't seem to matter. Sometimes it was a blue line and sometimes it was a few colors. I only see it on the lake. I have never seen it out in salt water. But I never fish that deep water in salt.

I will watch it next weekend and play with some of the controls to see if it changes.

I will post it if I find something.

That could be

I see it often, but not all of the time. Most times it's around 25'
