I am intending to bushwalk a remote unmarked trail near Brisbane alone. I will carry map, etrex30, compass, iphone4 and am likely to have phone reception. I will advise another person of my gpx route and when I finish the bushwalk. However, I would like to send a track or position every hour or so to this person, so that if an accident or injury or I get lost, etc then I can be located.
I will probably purchase a personal locator beacon if I do this more often, but this is a one-off and likely to very seldom happen so I would like to do with-out this time. I normally have others to hike with but others aren't available this week.
I don't want to run my phone battery down unnecessarily by running a gps tracking program. As the iphone has a gps chip that does not require an internet connection, I can run such apps offline but they still consume power and so far they seem very reluctant to a bit of track to an email address as and when I want to. There are apps you can subscribe to that can send a live track to a web site but they are not free and I don't want to pay....and they run the battery down.
I would prefer to maintain as much spare power capacity in the phone in case something did go wrong.
I think the best solution for me would be to jot down the current location from the etrex and send off a position each hour by email.
I was wondering what others do?
