Abstract
An underwater plow can include a depressor cam and a chute cam that are pivotably attached to a blade portion. The blade portion can be formed with a trough and the depressor cam can be biased in the trough. The chute cam can be formed with a groove having a minimum thickness at its attached end and an increasing taper to a maximum thickness at its distal end. A sensor passing through the plow contacts the edge of the depressor cam, causing depressor cam rotation away from the trough. The sensor passes the depressor cam and pushes against the chute cam, which causes the chute cam to contra-rotate relative to the depressor cam until the sensor passes through the chute arm at is maximum thickness. Once the sensor passes through, the cams contra-rotate back to their respective biased positions.
