Haglof Vertex IV
Haglof's number one best seller for the accurate height, distance and horizontal distance measuring you need in the field! The Vertex IV also acquires accurate readings in thick under-growth and measures an unlimited number of heights per object from any distance up to 30 meters.
The Vertex IV uses ultrasound to measure distances. Unlike, for example, measuring tapes and laser instruments, ultrasound can be used when there is no clear line of sight to the reference point. The ultrasound chooses the shortest way around any obstacle such as brush and stems.
Heights are calculated trigonometrically using the variables contained when measuring angle and distance. The Vertex IV automatically assumes that the measuring object is perpendicularly positioned to the ground.
Small and robust, the Vertex IV has an aluminium housing, sealed electronics and a large, easy-to-read alphanumerical display. A built-in tilt sensor allows for exact height measuring on slopes or hills. Easy calibration and built-in Bluetooth transmitter for direct transfer of measurement results for external storage and processing.
Batteries not included.
The transponder T3 is used together with the Vertex IV. The T3 is water resistant ,rugged and has a simple construction in a bright, visible colour. Works with one AA battery. Pin the transponder directly onto the tree or fasten with the adapter to the plot staff for 360��_�_ measuring.
