Bearing navigation

surfboomerang

I was playing a bit with the bearing navigation option in the Suunto 9 Baro and I am not quite certain how the watch will react in some situations.

See the situations below:

Bearing navigation has two options: With or without a distance.

Scenario 1: Bearing navigation with distance
In scenario 1 I start at point A and point the watch to point B which is 2km to the south.
Because distance is given, the watch creates a POI and starts navigation like POI navigation. That means that when I start moving towards point B, but I get distracted and end up at point C, the blue arrow will point towards the POI.

So in this situation I end up with:

A course of 180°
A heading of 200°
A bearing of 150°

Scenario 2: Bearing navigation without distance
Scenario 2 confuses me a little bit. I start again at point A and point the watch towards the south not knowing the distance.
Because no distance is given, the watch does not create a POI like situation 1.
I once again end up at point C. Can anyone what the watch will show me in this situation? Will the blue arrow point me back to the original course or will it keep showing a bearing of 180°?

So in this situation I end up with:

A course of 180°
A heading of 200°
A bearing of ?°

@surfboomerang logic tells me, that the watch will guide you to a point at infinity, therefore if you move perpendicularly away from the original line of sight, your projected target will move as well by the same distance by you are away from the original line.

@halajos That was also my initial thought, but that would make this feature rather useless.
I can then just regularly watch the compass heading to achieve the same.

If I remember correctly, Garmin implemented such a feature with a datafield that indicated how far you are (left or right) from your original course.

There was a similar discussion at release time, more or less around here.

@isazi Thanks! Totally missed those posts.

And wouldn’t you like to do so with big, useful numbers rather than repeated instructions?
