DiveNav, the developer of Nitroxbuddy, the world’s first Smartphone Oxygen Analyzer for SCUBA divers, announces their new dual-gas Carbon Monoxide and Oxygen analyzer.

Cootwo is a dual-gas analyzer that can be used to measure the percent of Oxygen in a breathing gas while also monitoring the presence of Carbon Monoxide. It also includes a temperature sensor and an ambient pressure sensor used to improve accuracy. Uniquely, cootwo allows a diver to analyze both Oxygen and Carbon Monoxide content of a tank without having to use 2 different devices.


Similarly to DiveNav’s existing Nitroxbuddy product, cootwo can be controlled via a smartphone or tablet. The user can program it, calibrate it and perform analyses. Upon completion of an analysis the smartphone creates a log automatically. Cootwo can also be used as a stand-alone device as it includes its own display. In this case, the device will save the log of the analysis internally and the user can retrieve it later with a smartphone or a tablet.

Lastly, cootwo can be used as an environmental data logger to sample and record the Temperature, Pressure, Oxygen and Carbon Monoxide content of the surrounding environment.

Cootwo contains a rechargeable Li-Ion battery and is compatible with DiveNav‘s My Nitroxbuddy app, which is already available for both iOS and Android devices. Cootwo has now been fully funded on Kickstarter. The list price is $299.
