Well... I have a hard time imagining to get location by yelling "where are you? " "by the trees!" It really sounds immensely useful to know last location (while they were still in range).

Use case: I was out, picking wild lingonberries in the forest with a group of ~10, some kids. At a "secret" location, with everyone wandering off in a direction they see more of them. Shouting did not help much.
