My dad and my brother and my uncle all work utei wilderness with wildlife management. They are in contact with each other by walkie talkies and so during the day. But now they have also found a new form of lone worker protection that we here at home can also be useful. Via GPS, we can follow where they are and they can alert if something goes wrong. My brother had the advantage of that yesterday when he was chased into a tree by an angry wolf. My dad and my uncle went there and anesthetized the wolf until they could get to safety again.
