DiverGuard is the ultimate underwater safety device and rescue tool for divers. By continuously monitoring breathing parameters, DiverGuard is able to intervene in the event of serious respiratory problems. It automatically sends an alert or, if necessary, initiates an active rescue by inflating the diver's BC. Like high-quality medical devices in similar applications, DiverGuard employs complex algorithms to evaluate breathing status correctly, while also monitoring the intermediate pressure in the scuba air regulating system. DiverGuard mechanical systems have been developed and tested by experts in diving gear manufacturing who are familiar with the complex performance requirements of systems intended for underwater use.
