Laser Rangefinders

forestry 550

ideal for basic forestry and land surveys — display in metres, yards or feet

• In addition to actual distance measurement, height, vertical separation (difference in height between two targets), horizontal distance and angle can be

easily measured.

• The results are displayed on both internal and external LCD panels. The external panel displays all results simultaneously.

• Two measurement modes (Target Priority Switch System) are available:

First Target Priority Mode displays the range to the nearest target taken from multiple results obtained with a single measurement.

Distant Target Priority Mode displays the range to the farthest target taken from multiple results obtained with a single measurement — especially

useful for forestry and hunting.

• Display in feet as well as metres and yards is available with this model.

• Measurement range: 10-500 m/11-550 yd./33-999 ft.

The specifications of the product may not be achieved depending on the target object's shape, surface texture

and nature, and/or weather conditions.

Note: The origin of the technique of this Laser Rangefinder with inclinometer is the Surveying Instruments incorporated measuring capability of both

distance and angle which were developed by Nikon Corporation. Among such products, especially, the first highly advanced electronic model, the Total

Station DTM-1, is the root (Sold in 1985).
