Portable LED HD Screen Golf Laser Range Finder 6X Magnification 5-600 Meters Measuring Rangered Condition: Item Type: Golf Range Finder Material: plastic Color: as picture shown Structure: single telescope Function type: ordinary telescope Purpose: civilian telescope Instrument magnification :6 Range: 5m-600m Range accuracy: 1M(5m-600m) Speed measurement error: ± 5KM/H Screen size: 1.8 inches Eye mask type: rotating Speed range: 20-280 yards Objective: 21 mm Magnification: 6X Angle of view: 72 degrees An exit pupil: 16 mm Resolution: +/- 1M Maximum range: 600M 1000M Nearest measurement: 600M, 4M, 1000M, 5M Battery: 3V (CR2) waterproof Length: approx. 97mm/3.8inch (including eyepiece) Length: approx. 106mm/4.2inch (not including eyepiece) Width: 39mm/1.5inch Height: 73mm/2.9inch (front) 68mm/2.7inch (rear) Principle: In the flagpole locking mode, point D can be separated from many background points, and only the distance d1 of the point can be retained, so as to automatically lock the flagpole and clear the woods behind the flagpole and other stray objects. Function: The distance measurement value AB and the slope value (greater than plus or minus 20 degrees) are put into the equation of golf flight trajectory, and the recommended hitting distance of golf is calculated according to the distance solution. Unit conversion: In the ranging MODE, long press the MODE key to switch the distance unit M(M)/Y(code). Mode selection: Short press MODE key to switch between "ranging", "speed measurement" and modes.
