I have sat nav in the car, gps when I'm out walking and a mobile phone. The mobile phone gets used mainly for text messages, I can't remember the last time I put it up to my ear. The gps only gets switched on for geocaching. Only once have I ever used it for navigation, and that was in a thick fog when I had been exploring and lost track of exactly where I was. The sat nav is always on when I'm travelling and gets used a great deal.

Technology - I love it.

Having spent many a dark and stormy night searching for lost souls, I would welcome a locator device. It could save lives and reduce the number of man hours spent searching.

I think, Blackpatch, that if you had spent the night out injured on the moors in wet, freezing conditions wondering if anyone would ever find you, you would be less critical of technology such as locators, gps and mobile phones. I've seen a grown man cry when we finally found him after line searching miles and mile of moorland because his companion thought he had left him somewhere else. Not a vision that I can forget!
