40 ounces son of a mother the fish I catch aren't 40 ounces
I haven't tested the 40 oz or the 24 oz versions yet but the 14 oz version is a killer on the Halibut.
They get pretty big the state record is 459#. Generally though 20# fish are the most common.
We have the worlds second highest tides. The biggest tides of the year will move over 30 feet of water.
