The compass on the map has a bezel you turn with your thumb, with a click under your finger so you feel where it lands.

Set a bearing and it stays set, with signal or without, so you can walk on it and come back to it.

Wind around you sits lighter on the map, under the terrain rather than over it.

Tap the little compass on the map. There is more to it than it lets on.
