Vertex 5

Vertex is many foresters’ preferred choice of instrument to perform precision height, angle and distance measurements in the forest.

Measure Distance up to 30 meters or 100 feet with a resolution of 0,01 m or 0,1 feet even in dense vegetation, and with an accuracy of +-1% or better if calibrated

Measure Heights up to 999 meters or 3277 feet with a resolution of 0.1m/0.1 ft

Measure Angles in Degrees 360°, Grads 400° or percent % with a resolution of 0.1°

5000 data sets can be stored in the built-in memory and saved as a CSV file

Bluetooth® 4.0 (BLE) can be used to transfer data wirelessly to devices with Android, iOS, or Windows

(BAF) Basal Area Function to determine the minimum diameter DBH that a tree most have, on sample point to be counted

Distance

With the well proven ultrasound measurement method and a high-visibility cross hair sight, the Vertex 5 offers accurate distance readings also in thick undergrowth. 

The ultrasound method works great in sample plot surveys, for distances up to approx. 30m/98ft, in dense forests and where there are difficulties to target. Sample Plots with Ultrasound

 
 

 

Heights

20200819 114016 Smal

Fast and accurate two-point measurement with the Vertex 5 system.

Fasten the T3 transponder to the tree at any height,
walk a distance of your choice and measure as many heights on each object as you wish,
with the four last measured heights shown in the display

  1. Aim at the transponder, press the button and read the distance to the object.
  2. Aim to the height you want to measure, press the button and read the height on the Vertex instrument display.

 

Angle

Measure slope in the terrain and have it presented to you in degrees, grads and percentage. Angle and Inclination

 

Plot radius

In sample plot inventory work it is important to use the correct radius measurement.The ultrasound method is very suitable for this application.

 

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. Basal Area (BAF)

 

Communication

Communicate with IR or Bluetooth. Transfer values to the MD II or DP II calipers, or other handheld units with HAGLOF dataformat.
