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 smooths 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 a gusts or wind shift.

The damping on the SC-1 can be set from anywhere from "d0" to "d9". 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 "d9", the displayed measurements in Compass, Speedometer and VMG modes are all averaged over approximately ten seconds.

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.

The procedure for adjusting the damping level on the SC-1 is illustrated below:

1. Unlock the buttons.
2. Put the lower display into Compass mode and put your thumb over the Plus button to increase the damping level or over the Minus button to decrease the damping level.
3. You will see the lower display scroll through different damping values.
4. When you see the value you want, release the Plus or Minus button. The display will switch back to normal compass mode operation and the new damping value will be applied to the Speedometer, Compass and VMG modes.
