By this picture please tell me how much this bass weighs
I know that an eye scale is tough from just a picture but give it a try.
I had it weighed in so I know the answer.
there's no way it's 9 or 13.
Did you use those spring scales, or the digital ones?
The spring scales get bad over time making your catch heavier or lighter than is.
He looks close to 60cm. And he has a a little bit of a belly so around 5 or 6lb.
