I go a lot by myself and my Dad, even though I am grown, is still very protective and worried about me when I go out alone. I bought a SPOT locator this year to help ease his mind. It goes directly off my Iphone and I can send him personally typed messages and he likes to watch where I am going. He said it was pretty cool because he could actually watch me walk down a canyon and back up. I can send an SOS message to him if say I just needed a little bit of help and it was something that wasnt super serious. If something does happen, it also has the 911 button on it where it dispatches my location to emergency services. It lets you map where you are going and lets you look at the map later on as well. It's a little expensive but is definitely a life saver if you really needed it and I think the price is worth the comfort I have knowing I wouldn't be lost and not found!
