Within the ShotView app itself, I believe that these answers are correct.
1-Without a session, is there a way to start adding firearms in the app?
No. There are no firearm profiles stored in the app. At the end of a session and after the session is transferred to the phone app, you can rename the session to something more meaningful.
2-Once I do have data, is there a method to add a target picture to go with a session or to note a particular shot?
At the end of each session and after the session is transferred to the phone app, you can add notes. You cannot add pictures.
3-Do I need to pair the two each time or I simply export data and add it later on the app or once exported is the data automatic?
No. You do not need to pair the Xero to the app each time you use it. You can create many sessions on the Xero and once paired to the app, all the sessions that have not been transferred will then be transferred.
It would be nice if Garmin did add:
- the ability to create/store rifle profiles
- the ability to copy session names and notes to another session or reuse names and notes from a previous session.
- the ability store pictures for a session
- the ability to ink to a Kestrel to store environmental data for the session
