My hand held likewise requires you to be moving, and in practice at a reasonable pace, before showing your current track (it still doesn't know which way its heading - you could be walking sideways!).

However, it also has a useful feature that in some of its display modes, it will show the present azimuth position of the sun or the moon around the outside of a compass rose. That way you can orientate the unit correctly if you can see either of them. If you can't, get your compass out!
