My son is a stay at home dad and trying to get by making DualFin Planers when he has time but sales are slow and Christmas is coming soon. I invented them but he makes them and we together decided to lower the price to see if we can get the business going. DualFins can come in very handy for river fishing or trolling. They are only 6" long and only weigh 1 ounce. You can put them on and take them off at any time. They plane to the side and flip direction when given a tug. It only takes a little practice to learn how to steer them where you want.
