the Depth sounder.
The store point screens above show the difference of setting the antenna heith
to 2 meters. The eleveation reading is 409.670m with no antenna height set
and 407.670m with an antenna height of 2 meters.
Set Water level
If the measurements are
based on a water level
instead of a GNSS
measured height set the
water level in the Depth

If measurments are to be based on a water level set it in the Depth Sounder
screen and turn on the water level flag. The Latitude and longatude location
will be measured by the GNSS receiver but the elevation of the lake or river bed
will be the depth sounder measurement minus the set water elevaton. The
store point screen show a measurement of 0.33m from a water elevation of
100m.
