The IQ 900 Zen from Tusa is their brand new dive computer packed with features that all fit on your wrist like a watch, making it perfect for not only diving but also to wear around the office or in town.

The Zen can be operated as a watch, air computer, Nitrox computer, digital depth gauge and timer or as a free dive depth gauge and timer. It has a large wording display making it easy to view and a backlit display further improves readability in darker waters.

The Zen features Tusa's Deep Stop function which improves safety by activating when your dive exceeds 80 feet, or 24 metres for more than one second. When ascending the Zen will display the suggested stop depth for two minutes, and although this is not mandatory and does not affect remaining No Decompression limits of the dive it is recommended.
