We got to take SPOT Satellite GPS messenger for a test run when my mom got one this year for her sailing trip. After having a couple incidents out on the sailboat where they were calling Maydays a couple years ago she wanted to be prepared and have a way for people to find them if something went awry.
She set up the device and service to email me a customized message every time she clicked the button on the SPOT. It would tell me that she was all right and her latitude and longitude. There was also an emergency button to click to send me an SOS message with her latitude and longitude.
While this service was meant for safety I found it fun to click the links on her e-mail and watch her progress as she sailed around the gulf and Caribbean. On the other hand, she got quite a few complains from other people she had set to send the e-mails to who felt as if they were being spammed by her check ins.
If you are ever in situations that a cell phone would not reach I definitely recommend getting this product. It is definitely advantageous for a child or elderly relative that you may worry about. But if you do purchase this product, I recommend only adding e-mails for people who you have forewarned and aren't particular about what they get e-mailed. And certainly leave out anyone who will jealously sit behind a desk while you are sailing the islands.
