The Element II can be operated as an Air computer, Nitrox (EANx) computer, digital depth gauge/timer or as a free dive depth gauge/timer.  The IQ-750 offers several desirable features including: Water-activation, 2 Mix Gas Switching ability,  a large alphanumeric and backlit display, audible and visual alarms, advanced user safety settings, and PC download/upload.  In addition to offering the latest comprehensive computer features, the IQ-750 adds a Deep Stop function for enhanced safety. 

Deep Stop Function
Several TUSA computers feature an optional deep stop function for additional safety. The deep stop mode is activated when a dive exceeds 80 FT (24M) for more than 1 second. Upon ascent, the computer will display a Deep Safety Stop screen and the recommended stop depth for a period of 2 minutes. This deep stop is highly recommended as additional opportunity to off-gas, but is not mandatory. If the diver chooses not to serve the stop it will not adversely affect the remaining No-Decompression Limits of the dive.
