I would like to encourage everyone to evaluate the tracking difference between SPOT and InReach. There is not better comparison than to watch the SSA Sailplane Contest Tracker at SSA.org. The 18 meter nationals are occurring this week and the action is live as well as archived at SSA.org. Go to "race results" and you will find the tracker archive in a column beside each day. Only on the race page will you also find the task defined (not to be confused with the general tracking map).

The current day is "live" and the past results are "archived" for ever and ever. There is also visible satellite imagery archived every thirty minutes. Swipe the timeline at the bottom to march the pilots around the course. Sean's InReach is much more reliable, consistent and shows altitude in the info block.
