Currently (October 2021) the tracker reports our position every 30 minutes. Early in our trip it was set to 10 minutes, however that generated too much data. We usually travel at about 6 knots, with 10 minute intervals that yields 6 updates an hour. Setting a longer reporting interval also reduces the power consumption, something about which we are very careful. The Spot is only turned on when we are moving, so there will be time gaps when we are anchored or at a dock. And sometimes we forget to turn it on before we leave, which makes for an unusual track, for example leaving Block Island or Cape May.
The Spot map will not show more than 500 data points at a time. The time ranges can adjusted to see where we are at different times. When a custom time range is used, the arrows will advance or backup the time frame.
