The spiral routine requires a minimum of two passes through the casing, but better results are obtained by four passes through the casing: the first oriented in the A0 direction, the second in the A180 direction, the third in the B0 direction, and the last in the B180 direction.
With English spiral sensors, readings must be taken at depths that are multiples of 5 feet. With metric spiral sensors, readings must be taken at depths that are multiples of 1.5 meters. This requirement affects the way you must record readings with the Digitilt DataMate. See instructions below.
