An XR glasses-equipped underwater exploration helmet and a method of operating the same are disclosed. The XR glasses-equipped underwater exploration helmet includes: an XR execution module creating XR data; an XR display displaying the XR data created by the XR execution module; a GPS module creating GPS location information; and a GPS signal wireless transmission module creating in real time a GPS wireless signal including the GPS location information created in real time by the GPS module, and transmitting the real-time created GPS wireless signal, wherein the XR data are composed of at least one or more of a current water depth, a current underwater temperature, a dive time, and a remaining air volume. According to the XR glasses-equipped underwater exploration helmet and a method of operating the same described above, since an XR glass is mounted on an underwater exploration helmet and is configured to display data such as a remaining air volume of an air tank, a water depth, a water temperature, a dive time, an available dive time, etc., so there is an effect that a diver can conveniently explore without having to frequently check a diving computer or gauges during diving.
