Magnetic underwater slates meet cloud-powered mapping

DeepMark provides instant-erase underwater writing slates with QR-encoded signage that divers can rapidly deploy to mark navigation paths, share discoveries, and leave emergency information.

✨ The Wow Moment

A diver discovers an underwater cave entrance and instantly deploys a floating marker. They sketch a warning on their slate, snap a photo that uploads to the cloud, and 30 seconds later another diver's HUD displays the exact danger zone with the original sketch — creating a living, crowd-sourced map of the underwater world that updates in real-time as teams explore.
