Most dive computers today are made as digital watch computers or console style but Tusa IQ-850 DC Sapience II is quite unusual model from the line of Tusa dive computers. It is made as a wrist unit with large, thin and dot-matrix monochromic display. Other distinctive features are vibration, during alarms or warnings, and big Nitrogen Loading Tissue Bar Graph on the top of the screen.

In No-Decompression mode upon reaching certain conditions, dive computer may give us Safety Stop prompt with ‘Safe Stop’ notation and countdown timer. If we miss recommended Safety Stop – there will be no penalty.
As other dive computers, Tusa IQ–850 has few other useful warnings – Ascent Rate alarm, High PO2 and High Oxygen Limit Indicator (OLI) warnings:
When we exceed our No-Decompression Limits – Sapience II activates Decompression dive mode and all calculations are related to this mode from that moment.
Tusa IQ–850 dive computer will display few stops with appropriate depths and times to complete decompression. In addition to Elapsed Dive Time, current depth, FO2 values and other dive data display shows following decompression attributes:
When we finish with first stop, dive computer will display another one at shallower depth. We need to ascend safely to that depth and stay at that depth or a bit below until stop timer reaches ‘zero’, and so on. When decompression process is completed – we may resurface safely.
If in some reason you didn’t perform decompression – dive computer would lock itself and display would freeze. Only after 48 hours it will wake up in Time mode, which is default mode for Sapience II.
