GPO Rangeguide 2800 Rangefinder/Binocular 10x50 LRF. The RANGEGUIDE 2800 impresses with features that are hard to find in this price-performance class. Again, we use a magnesium housing to achieve maximum robustness with minimum weight. With a maximum range on well reflecting targets of 2.800 meters, the integrated hyperscan mode which allows the laser to work with 4 measurements per second and therefore an extremely fast measurement in scan mode, the BEST/ LAST technology, the temperature sensor, and the SLOPE and TRUE RANGE calculation, you get a product which has been developed for all eventualities and without compromises. The menu function is intuitive and the control buttons are ergonomically placed on the product.
