With an active data connection, MotorolaTalkabout and the t800s work great. Unfortunately, most of the time I want to use these where there is no cell signal. In this case, the poor support for offline maps makes them nearly useless. The maps download incredibly slowly, even on a very fast Wi-Fi connection (so slowly that you really need to know where you are going to be within a few miles well beforehand) and then even after they download, they may not display when you are in the field because MotorolaTalkabout is very buggy. Without the map overlay, all you get is “the other person is in that direction… maybe”. If these issues were fixed, I would buy a dozen of these radios!
