I Bought that Tool for landscape photography and it's really massive tool to save your coordinate position and compass way، also the time of updating position of camera also can be adjustable as each 1 second, 5 second, 10 second or more, all my images are conected in lightroom to aerial surface of google earth.
Pros: good battery life, quiet, Nice features/settings, Quick Start-up time, Superior build quality, Lightweight/Portable, Simple controls/menu, easy to use
