BAF- Basal Area Factors
Working with factor gauge or prisms can be difficult when some trees cover others in the forest. Poor sighting can prevent a correct diameter measuring.
With the Vertex IV built in BAF function, the minimum tree diameter for trees to be included in the plot can be featured.
Communicate with IR or Bluetooth. Transfer values to the MD II or DP II calipers, or other handheld units with HAGLOF data format.
