Abstract
A trolling device for movement through a fluid includes a movable element and control apparatus for selectively stopping the movable element to control the movement of the trolling device through a fluid according to a detected physical parameter. In one embodiment, the movable element comprises a paddle wheel and the control apparatus includes a bellows which stops the wheel causing the device to dive when trolled through a fluid such as water above a predetermined depth. When below a predetermined depth, the wheel is allowed to freewheel permitting the device to ascend.
