Abstract
A trolling depth adjusting device is disclosed which includes a vane having a forward corner with a first hole and the aftward corner having a second hole. The device further includes a principal line passing from the upward facing surface of the vane, slideably through the forward corner to the underside of the vane and then passing from the underside, slideably through the aftward corner and terminating in a lower end connected to a fishing hook. The device further includes a weight slideably mounting on the principal line and unique adjustable stop mounted on the principal line between the lower end thereof and the second hole in the vane. The weight forces the vane to slide downwardly on the principal line toward the stop when the tension between the trolling line and the hook is relatively low, causing the vane to be disposed at an acute attack angle with respect to the pulling force direction of the trolling line, enabling the vane to apply a downwardly directed reactive force on the trolling line as the vane is pulled through the water. The principal line forces the vane to slide upwardly when the tension between the trolling line and the hook is relatively high, causing the…
