Chapter 1: Operation
1.1 Introduction
The ST30 Round Bidata instrument is designed for the powerboat
market, and displays speed and depth information simultaneously on a
split LCD. The Bidata can also display trip and log distances, sound a
user-defined shallow alarm, and function as a repeater.
The instrument can be surface or flush mounted and fits the standard
85.7 mm (3
3 /
8
inch) diameter facia apertures, common on many sports
boats.
The Bidata uses an easy-to-install transom mount transducer (Biducer)
combining both speed and depth elements in a single housing.
If the Bidata is used in conjunction with a SeaTalk autopilot, the speed
input provided by the instrument enhances the pilot's steering
performance.

The Bidata can display depth and speed information in metric and
imperial units. These are set during basic calibration (see
Chapter 4,
Calibration) .
