Thinking about getting one of these devices. Primary use would be for my husband to take on bike rides to be able to contact me for pickup in case he has some sort of problem. Secondary use would be for me to take hiking to send him messages. Most of the area where we will be biking and hiking has no cell phone coverage, so using cell phones is not really an option.
At this point we're leaning towards the Delorme.
Or maybe we'll choke on the price and not get anything at all.
