Anyone who plans on being in the great outdoors should carry and know how to use a GPS (Global Positioning System)They aren't as difficult to use as you may think. I have one of each. I recently purchased the Rino for myself and I encourage those who explore with me to have the Rino as well. We use the radio to communicate with each other and it gives you the location of your partner. They are awesome! And you can't beat the price!
