Bushnell made it better, faster, and stronger with the Tour V4 Laser Rangefinder. JOLT Technology uses short vibrating bursts to confirm PinSeeker Technology has isolated and locked onto the target, eliminating any doubt, and a faster processor translates to faster yardage readings. Multi-coated HD Optics with 5x magnification provide yardage accurate to within a yard from a range of 5-1,000 yards. The new ergonomic design is 30% smaller than the Tour v3, making it even more convenient to carry.
