I know it’s not quite the same but sending a free message about every hour also easy to just send one when you stop for the hourly snack/drink, works for me -just says something like ‘zipping along having fun’. Three button presses and done. Takes all of 5 -10 seconds.
One at lunch and send one at 8 am “setting off’ and 8 pm ‘stopping for the night”
I have the big Garmin Inreach one and the battery lasts for about 7-8 days and on all the time/or sometimes off at night.
Would rather use the toggle on the big one than trying to BluTooth to the phone-one device one job. Phone lasts 4-5 days also on airplane mode.
