Brizo is another underwater gadget, which has been developed for marine biologists to help with underwater activities and contribute to marine environmental monitoring and conservation.

The device is able to GPS geo-reference the starting point of a dive on the water’s surface or onshore and it can record the 3D diving path underwater with a depth of 120 meters. Brizo records altitude, direction, diving length, velocity and acceleration. The device is not a positioning device but a multi-parametric probe, recording physical and chemical data that helps users understand the sea environment.
