I have a 1 year old DeLorme Inreach satellite communicator. We used it for 1 trip from Guatemala to Florida last year, and it has been sitting ever sense. This uses the Irridium network, and works worldwide. We used it to allow our friends to track our progress, and to send text messages. The data plans are reasonable, and it worked very well.
New cost is $300, and I will sell for $150.00 plus actual shipping cost. I'm located in St Augustine Florida if you wish a local pickup. It is in new condition, and will send pictures upon request.
