They tell you what bottom you are fishing on yellow tells you it's gravel so use a gravel rig white tells you it's gravel so use a gravel rig and finally green tells you its weed your fishing on so use a weed rig. Hope that helps.
Yeah. I understand these. But above the 1,2, or 3 Black circle when you put down rod, there is a semi circle on the outer ring of the black bubbles. Sometimes blue or white, sometimes full, or depleted.
I believe the band above the rod indicator is a water clarity indicator. I have no documentation to support that but I have always assumed that was it's function.
The Semi Circle is not as curved as a standard full circle hooks and this means they are a better option when baiting up with worm etc LiteBlue.
