There is a flaw in that plan. It would go off every time you left the thing
on charge overnight!
That I think is why such things get built into the watch. False alarms are
not much good.

Sounds like a good idea for many people actually.

About £200 for a non-floating one, the kind normally used on land.

They aren't intended to be used in areas where 'normal' methods (mobile
phone etc) work. In the UK, at least on land, people like hill walkers
etc
would be the expected users plus, of course, people like the chap in the
article.


Every now and then you hear of the havoc caused due to one being set off
in
error, maliciously, or by some fluke- mainly maritime ones.


There are cheaper ones but if they communicate via satellites, you need a
subscription and it's not cheap.

Eg. SPOT Gen3 Satellite GPS Tracker

There are versions that work through the mobile phone network but
obviously
you need mobile reception for them to be sure to work.

If there is a phone network available and you know where the person is is
there an app for a smart phone that will call someone if you do not move
for 5 minutes. I cannot find one but would like one.
