Tracking distance resolution

If you are talking about tracback:

„While the inReach Messenger is powered on and connected to satellites, it automatically records its location every 10 minutes to create a hidden trip log in the background that contains tracking data. This hidden trip log is what will be used when starting a TracBack.“

The 10 min interval is not user configurable.

If you talking about sending tracking points, depends on your signed plan, if it is user configurable (and additional costs per tracking point).

Thank you for this information. It's very useful indeed. I was actually referring to when a 'Tracking' session is started. It's great that the device doesn't repeatedly record its location when not moving but I was wondering how far it has to move before it records a new point and whether this distance is configurable. When it is moving it can certainly record points every two minutes with the plan I've taken.

Thank you very much Volker. This site basically answers my question. 

Hi you don't know by any chance what the maximum number of track back points the unit will store before they are overridden ? I could not find anything in the spec or manual regarding this , many thanks 

I'm sorry, I have no idea either.

Given that the maximum TracBack "time" is 24 hours, and given that TracBack points are not necessarily at even time intervals, I would guess (and it's only a guess) that the number is quite small. Unlike other iR devices, the iRM does not offer the ability to sync and view the logged track. Another indication that the automatically spaced points are few and sparse.

If you want a definitive answer, you'll probably have to open a support ticket. Please post back with the answer if you do so.

Thank you for the information much appreciated
