Like the larger StingRay 8 the Stingray 6 utilizes Stealth’s proprietary FidelityGlasstm solid-front radiating surface and sports an unprecedented environmental protection rating of IP-68 as measured to IEC standards, which ensure the StingRay’s internal components are fully isolated from any intrusion of dust or moisture. StingRay is rated to be fully operable underwater for up to 64 hours at 1M depth and can withstand rain, snow, sleet, hail, sun and dust in temperatures ranging from 0 degrees F – 150 degrees F.
