Together with Zoleo, our unique package of tools and services monitors lonely workers, hikers, divers and extreme athletes 24 hours a day. The person in danger can send us an S.O.S. signal at any time, which we receive with a single satellite without mobile network everywhere, always, and we immediately start rescuing the person on land, in water, in the air, based on the exact GPS. coordinates. The product operates for 72 hours on a single charge and lets you know with clear sound and light signals that help is on the way or that the S.O.S. signal has been sent. The device is resistant to shocks and splashes of water. Contact us for details and request further information.
