The Trimble XR10 with HoloLens 2 is designed, tested, and certified to work with any MSA V-Gard Cap Style or Full Brim hard hat. The device comes pre-assembled with the hard hat included, but users are welcome to swap in their own MSA V-Gard hard hat, if desired. Other brands of hard hat are unlikely to work with the Trimble XR10 with HoloLens 2 fit system. The Trimble XR10 with HoloLens 2 can be easily detached from the hard hat and moved to another.
