Long before target lock and whatnot came out, I would have the FW snorkel around structure and she would release a breath of air that would tell me where the fish were.
I would then cast just ahead of where I saw the bubbles come up and usually do pretty good at catching fish until one day a bunch of bubbles came up and I casted to the spot and hit her in the back of the head with the jig I was using.
Seems that bunch of bubbles was just a ways back of where they should of come up normally.
Ain’t got no FW no more besides I kept snaggin her in the back when i did.
