Head-up dive computer – Discover māoï – Smart, easy-to-use

Thalatoo presents its head-up dive computer māoï,

experience the ocean through māoï

Unique, māoï is the first head-up dive computer from Thalatoo. Concentrate of technology, its compact housing fits very easily to every kind of masks. You said innovations? A transparent screen displays safety information, without any disruption of his field of vision. A smart mode adapts to the situation of the diver by displaying the strictly necessary information when required, improving the underwater experience without any sacrificing to safety. Simple programming makes it possible to upgrade the dive profile from recreational to more technical levels, but also to access new functions (compass, multi-gas …) and some evolutionary updates.


So under water, keep your head up … dive māoï!

Head-Up Dive Computer

MĀOÏ is first and foremost a dive computer. It makes all the necessary information available: depth, dive time, decompression management, ascent rate, etc. And to make the diver’s life easier, the information is displayed in a way that makes it useful. For example, the heading displayed corresponds to the direction you are facing.

Algorithme de décompression


The Bühlmann ZHL-16C algorithm is the most frequently used in the dive world. So we use it in our computer. Our decompression models are validated by a completely independent certifying body, experts in the field of diving. We leave nothing to chance when it comes to safety! In fact, MĀOÏ allows you to manage the stages of decompression, regardless of the number of dives made during the day. It calculates the time remaining without decompression, the information necessary for staged decompression, the no fly time.

Your MĀOÏ keeps the last 100 dives in its memory. Divers can either automatically or manually transfer their data to the main online diving logs. They, therefore have the possibility of saving and consulting their dive profiles (times-depths-alarms). Several of these free sites allow divers to associate photos, videos, and observations to the dive… and to share them with their friends.



MĀOÏ is based on head-up display technology; in the smart mode, information are visible only when necessary. For example, the ascent rate is only displayed once the diver starts its ascent. And more of all, the transparent screen maximizes the diver’s field of vision.


MĀOÏ was developed for all divers. The information can be read effortlessly by long-sighted divers. If you wear prescription glasses or contact lenses when diving there is no problem, as MĀOÏ is compatible with any type of corrective lenses.
