What a fishing weight! I'd hate to see the hook .... wait, you don't need a hook, just bonk the fish in the head with it!
Might consider giving it a nice coat of gold paint, for that "Ft. Knox" style
That's a standard issue item for rock cod fishing out here, it will sit at the bottom of a string of 5-15 baited hooks or lures and be dropped down 300-1000 feet. There were occasions when you could limit out on your first drop, but not any more. Without that much weight you'd need a few thousand feet of line to get down to the bottom with the current.
Not sure about gold paint, but a couple of glow sticks usually improved the catch.
The cool part is that you only need to lift the string up a couple hundred feet before their bladders inflate from the lighter pressure and the whole string of fish floats to the surface......
