20 CALIBRATION
Most users leave Full Point at zero.
Note: The transducer has a blind space near its face where there are mechanical limitations that prevent
detecting a target. The SonoTracker Series controller comes defaulted with a minimum range equal to the blind
space for the transducer. If you leave Full Point at its default of 0 or enter a Full point less than Minimum Range,
be aware that the SonoTracker Series will not detect or report levels at the top of the Span.
