Damping Adjustment
Damping on the SC-1 corresponds to the degree to which the raw GPS data is averaged over time before
it is displayed. A high level of damping represents averaging over a long period of time. Damping has
the effect of smoothing out the displayed data while low damping allows the displayed data to update
faster.
High damping is good for evaluating different trim settings as it smoothes out spikes in the
measurements resulting from gusts and wave action. On the other hand, low damping will help you to
quickly identify the effect of gusts and wind shifts.
The damping on the SC-1 can be set to 10 different settings, "d0" "d1" "d2" "d3" "d4" "d5" "d10" "d30"
"d60" and "d90".
When the damping is set to "d0" there is no time averaging and the displayed measurement corresponds
to the most recently available GPS data.
When damping is set to setting "d1" through "d90", the displayed measurements in compass,
speedometer, tactical compass, VMG and start line proximity modes are all averaged over approximately
the number of seconds following the "d". "d1" displays measurements averaged over approximately 1
second, "d2" displays measurements averaged over approximately 2 seconds, etc...
We recommend that you experiment with different damping levels. The optimal setting will depend on
your boat, the conditions and what you are using the instrument for.
