Automated reporting
G8 is the most connected safety wearable ever made. With one device you can detect gas, protect lone workers, and give teams instant ways to call for help or collaborate. G8 shares data in real time so you can see what's happening, respond faster when something goes wrong, and spot risks before they become roadblocks.
