While it might be something neat for other applications I think it's a bit too much for just a simple buddy box used in training. All of the reasons they list for a simple buddy box are really not applicable in a training environment. You WANT the student standing right next to you so that you can talk to him, see his actions, and possible physically help with items on his radio such as trim settings. Plus, it's a lot of cost just for trainging a student. Stick with a buddy cord for initial training of a student.</p>
