Hello everyone! 
Through improved noise reduction, weak signal processing is optimised (SNR increased 4 times). Less light refraction and crosstalk with optimized optical structure. Better alignment with coax-is mechanical improvement. Multiple methods for data transfer 
Up to 1500m reflector-less range with quick response in 0.3s. N6 can easily handle the target in tough conditions, eg. roof, wires. also enables N6 to achieve accurate (2+2ppm) measurement in 5.0km with prism.
