MyFishFinder.com Just like iceshanty but warmer
I have noticed the last couple times I have gone out, that whenever I drop a line there are green marks following my jig down. Eventually they disappear, within 20 seconds or so. Ususally it only happens when I am using minnows, but it has done it with wax worms as well. I know that the green flashes are nothing, but I'm just curious as to what is causing them. I usually keep the gain around two if that helps with the answer.
...I see this too..I am pretty sure it is line twist.
sometimes i notice it when my line is coiled. maybe thats part of it?
Have you ried turning your gain all the way down. What model do you have/ are you looking at the zoom mode on the FL-20?
Its is definitly line twist. Once your lure hits its final depth the weight usually pulls out the twists. Also an indication that it may be timew for new line.
