Abstract: A self recording meter for recording water currents is described. The current meter comprises a housing having a vertical axis, three accelerometers each having a sensitive axis mounted at 90.degree. to each other within the housing wherein the sensitive axis of one of the accelerometers is coincident with the housing vertical axis, and the other axes are substantially horizontal, a magnetic compass disposed within the housing for measuring an angle defined between magnetic North and the sensitive axis of one of the substantially horizontal accelerometers, a depth sensor, and circuitry for emitting electronic signals from the accelerometers, compass and depth sensor indicating magnitude of horizontal current relative to depth, direction of horizontal current relative to depth, and magnitude and direction of vertical current relative to depth.
