InstaCaliper: Measure Trees Accurately with the Caliper Head

Techniques for accurate tree measurements

Hold the InstaCaliper so that the caliper head is parallel to the ground.

  2.  Slide the caliper head around the tree trunk at a constant speed until the tree touches the caliper head at the back.

  3.  Slide the caliper head in the opposite direction away from the trunk using the same motion, keeping the caliper head parallel to the ground at all times.
