Technologies

Digitally eNhanced Accuracy (DNA) engine delivers measurement resolution to 1/10th yard in under 1 second

Smart Key locking face plate enables TGR and Club Selector when attached

True Golf Range (TGR) displays an adjusted range based on distance, shot angle, temperature, altitude, and the unique ballistics of a golf ball

Prism Lock looks for, and locks-on to, the highly reflective prisms set up at key points on certain courses and at the top of pins

PinHunter filters out background interference and ensures the range to the pin, not what's behind it

Quick-set menu provides fast and easy one-handed access to all of the GX-4i features and options

Club Selector recommends clubs based on TGR and your specific striking distances

Fog mode filters out false readings that can be caused by fog and rain droplets

Improvements to the Prism Lock and PinHunter2 hardware and software makes detection and acquisition faster than the earlier version, with greater range and accuracy
