I worked hard to develop what I call the DualFin an ultralight planer/surf board. It has all the features you could ever want when trolling for any species. The surf board action keeps them riding high and it has more planing power then you think for its size. It is 6 long and only weighs 1.2 ounces for high sensitivity.
It breaks down to fit in the draw string bag that fits comfortably in a pocket.
Here is short video in the table top test pool. Dont try this in your garage!
Even eminent chartered accountants are known, in their capacity as fishermen, blissfully to ignore differences between seven and ten inches, half a pound and two pounds, three fish and a dozen fish. ~ William Sherwood Fox, Silken Lines and Silver Hooks, 1954
