Chain & offset method
To use this method you must have two reference nodes positioned in the survey and know the chain distance and the offset distance, measured using a tape measure or a laser rangefinder.
- Tap
. -
Select the two reference nodes that define the construction line: tap
and then tap the first node, then tap 
and tap the second node. The construction line appears on the map.
- Measure the horizontal chain distance from node 1. Tap
and enter the distance. -
Measure the horizontal offset distance. Tap
and enter the distance.The target node appears on the map.
- Tap the map to toggle between the two possible calculated positions for the target node.
- Tap
to create the node in the position shown.
