The Blade Slope is a tournament legal, golf laser rangefinder with 6x magnification, capable of ranging reflective targets up to 1400 yards and hole flags up to 350 yards at +/- 1 yard. The Blade Slope comes with and runs off a CR2 battery. Slope Mode provides a slope-adjusted range displaying two ranges (line of sight on top & slope-adjusted below). External, green LED indicators illuminate when Slope Mode is on. When off, the LEDs will be off, and the rangefinder is tournament legal. PinSpotter Mode provides visual and vibratory feedback to confirm a ranged flag. The rangefinder vibrates 3x and a flag symbol will flash in the display 3x and then remains visible when a flag has been ranged. With the ability to switch between Scan, Line of Sight, and Slope Mode, find the ranging mode best for you. The Blade Slope uses a black LCD display, offers three reticle options (circle, crosshair & circle crosshair) and an adjustable diopter. Built on a polymer chassis with rubber armor, the Blade Slope is both waterproof and shockproof for all weather performance. A built-in, cart magnet allows you to securely place it on your cart or any other magnetic surface between shots. Backed by our unlimited, unconditional, lifetime, VIP Warranty.
