Overview of using a 2 point offset
A 2 point offset enables you to create a point based on two reference points (A & B). The reference points can be set using a pen, GPS, or manually entered coordinates. There are two variations available in ArcPad for the 2 point offset: distance– distance and bearing–bearing.
A distance–distance offset is used when the bearings are not known from the reference points but the distances are. For example, when you are using a rangefinder without a compass.
A bearing–bearing offset is used when two bearings are known for the reference points but the distances are not. For example, when you are using a compass without a rangefinder.
