Ah…I used to have my Garmin Aera setup with a 30 minute reminder…but now I use an ipad mini…which is so much better than the Aera…but sky demon doesn’t have the reminder function…
I think I can set up a reminder timer on the 430…I’ll have to figure it out…
Yes but if your power goes, the 430 won’t be much good 
I built that timer at a time when Apple shares were worth about 1% of their recent peak
