PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678), Ascent Rate Indicator (U.S. Patent no. 5,156,055).
CE
The CE mark is used to mark conformity with the European Union EMC directive 89/336/EEC. TUSA dive instruments
fulfill the required EU directives.
EN 13319 "Diving accessories - Depth gauges and combined depth and time measuring devices - Functional and
safety requirements, test methods" is a European diving depth gauge standard. The Element II is designed to comply
with this standard.
DECOMPRESSION MODEL
The program within the Element II simulates the absorption of nitrogen into the body by using a mathematical model.
This model is merely a way to apply a limited set of data to a large range of experiences. The Element II dive computer
model is based upon the latest research and experiments in decompression theory. Still, using the Element II, just
as using the Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression
sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine
can predict how your body will react to a particular dive profile.
