Water Temp Sub Tab
The Water Temp sub tab enables you to control the temperature log (if your boat
is equipped with a temperature transducer/sensor). The graph reads from right to
left, so that the most recent temperature measured appears on the far-right side
of the log. The dotted lines within the graph indicate intervals in the temperature
scale and the duration of time.
The following settings are available:
• log and Graph Scale—sets the temperature range (in degrees) to
display on the log and on the Sonar Page. Select Auto to have the unit
automatically determine the best range, or select a Span of 2, 4, 6, 8, or 10
degrees.
• log Duration—sets how fast or slow the temperature log scrolls (the
shorter the time duration, the faster the temperature log scroll). Select a
duration from 1 Minute to 2.5 hours. 10 Minutes is the default.
• temperature log—records the water temperature as you move through
the water so that you can look for temperature changes over a period of
time.
