Hey there.
I'm in the process of achieving precision landing via fiducial marker and I thought setting the offboard mode on VOXL2 to "follow_tag" would be a part of that but before flight testing I tried researching what that setting actually does and your SDK gitlab that is linked from your VOXL Vision Hub-guides page says it's for R&D only and that "the drone will follow [the tag] around". 
Do I even need to use offboard mode to achieve precision landing or is PX4's "Precision Land" flight mode utilizing VIO already enough?
best regards

@m4v3r that mode follows an apriltag in offboard mode, that's it. It's for demo purposes only.

@Moderator I was thinking details, like at what speed and altitude etc.?
