Depending on the surroundings The Haglof Vertex IV Rangefinder can be used in different ways. In areas with thick vegetation this surveying tool performs very good using the ultrasound technique. In order to use the ultrasound we would need the optional T3 Transponder, in fact the transponder can be used with the Vertex IV to measure heights placing it directly to a tree or a pole. The Vertex IV can even use a monopod staff to measure full circles for sample plots. To attach the monopod to the transponder an adapter is needed. This is an excellent feature for engineers and land surveyors.

The Vertex IV Rangefinder features the BAF function. This option allows you to point sample an area, that is basically a method used to sample the trees based on their size rather than the amount of them. Using the Basal Area Factor this tool also determines whether or not to count a tree on the sample, it does a really good job sampling the borderline trees.

The Haglof IV also works with different measuring units: meters, feet, degrees, grads and percent.

The Haglof IV Rangefinder uses 1 AA alkaline battery and the battery life is phenomenal. It comes in gray and it only weights 5.6 oz., it's also water resistant and rugged. This very small and robust tool comes with a 1 year limited warranty.
