This dive computer fits the bill for many divers of different interests and diving experience. Along with it, Nitrox comes standard up to 56% and allows for configuration for the safety factor – conservative, normal and aggressive, very similar to that of Suunto’s function on the D5.

The interface is clear and easily read when underwater (honestly the interface looks exactly like a Teric without colour), and it comes with back light which turns on when you hold it up.

Sporting a very respectable 25 dives with back-light turned-on on, a full charge and 3 months on standby mode. In our last 8 days Bali trip (18 dives), we have only full charged it once when we landed. The computer uses rechargeable lithium-ion battery. The battery life is exceptional even in comparison to dive computers 2-3 times its price. It also comes with fast charging (up to 85% in 1hr).

Bottom time and depth can be easily set through the menu and the diver’s residual nitrogen time, dive settings and logs are easily resettable.

Hardware wise, the computer has a screen resolution of 110×110 pixels along with 316 stainless steel bazel and K1 tempered glass, its sure able to take a good beating. And did i say it was almost half the size of a Zoop
