ABSTRACT:
A dynamically balanced apparatus for water borne instruments such as current direction and velocity meters having a stand off support rotatably secured to a cable whose lower end is anchored and its upper end attached to a buoy. A swivelled connector extends from the free end of the stand off to the mid-portion of an elongated cylindrical housing, the latter being rotatably mounted to the connector and weighted along its lower portion whereby the housing assumes a normal predetermined horizontal position at all times. A duct symmetrically disposed at each end of the housing and a water velocity and direction member mounted in each of the ducts. A pair of rudders extending rearwardly of the connector whereby the housing is constantly maintained in a direction facing the current and the ducts in a horizontal position for recording the direction and velocity of the current accurately.
