ENOS® is an independent GPS search system that allows for the location and rapid recovery action of a diver who is lost or in difficulty in any marine weather condition.
This system is used in scuba diving operations in various parts of the world, from the Galapagos to the Maldives, from the Seychelles to the Black Sea, and has also obtained approval from the German Maritime SaR




SIBO.1: the first surface marker buoy (SMB) designed to keep an ENOS transmitter above the surface. This SMB is equipped with a pocket on the top, ideal for placing the ENOS transmitter. In this way, divers can send their ENOS signal during the decompression stop or even during the breathing phase, if no bubbles are visible from the boat.
The SIBO.1 also supports the use of flashlights. Instead of the ENOS transmitter, a flashlight can be placed inside the pocket on the top. Thanks to the height reached, the light from the flashlight is more visible.
To avoid losing the ENOS transmitter, a spiral cable is connected to the SIBO.1 to secure the signaling devices. Its length of 1.85 meters (6.07 feet) makes it highly visible even in case of high waves, and the robust material always keeps it in a constant position.
The SIBO.1 is made in two colors to ensure optimal signaling effect in different light and visibility conditions:
It is delivered in a separate pocket with carabiner for convenient attachment to equipment before the dive. The pocket can be removed from the SMB when necessary
