Depth Offset

The depth offset is added to the measured depth value before it is displayed. You
can specify the depth as a positive value (WATERLINE OFFSET) or a negative value
(KEEL OFFSET). The depth offset can be set adjusted in 0.1 increments of the units
you have assigned for Depth Units in the setup parameters of the display unit:
meters, fathoms, or feet.
The default is 0.

Speed Calibrate

If the transducer is equipped with a speed paddle wheel, the unit calculates the
speed of the boat through the water. The speed calibrate option enables you to
adjust the displayed speed so that it matches your actual speed through the
water. You can adjust the displayed speed from 1% to 200%. If the reading is too
low, set Speed Calibration to more than 100%. If the reading is too high, set
Speed Calibrate to less than 100%.
The default is 100%.

Temp Calibrate

If the transducer is equipped with a thermistor, the DSM25 calculates the
temperature of the water. The temperature calibrate option enables you to adjust
the displayed temperature. You can adjust the displayed temperature by –9.0°F to
+9.0°F or –5.5°C to +5.5°C.
The default is 0º.
