1. Intended use
The Suunto EON Steel dive computer is designed for use as an optional diving equipment for
recreational diving. Suunto EON Steel is intended for use in various types of scuba diving, for
example, air, nitrox, trimix and CCR diving. In scuba diving use Suunto EON Steel dive
computer displays important information before, during and after the dive to enable safe
decision making. The most important pieces of information are dive depth, dive time and
decompression information. In addition, Suunto EON Steel can show the user other dive
related values, such as ascent speed, water temperature, and compass direction. It also helps
the diver to plan the dive and to follow through the dive plan.
Suunto EON Steel can be used as a standalone product or in combination with the Suunto
Tank POD, which measures the tank pressure and transmits the pressure reading information
to the Suunto EON Steel dive computer. The combination of the Suunto EON Steel and the
Tank POD is a Personal Protective Equipment under the EU Regulation 2016/425 and protects
against risks listed under PPE Risk Category III (a). Backup instruments, for example, depth
gauge, submersible pressure gauge, timer, or watch must be used. The diver must have
access to decompression tables whenever diving with a dive computer.
