The Smart Apnea computer watch is the evolution of the Nemo Apneist and has become the reference computer for spearfishermen and the most demanding freedivers.

The Smart Apnea is a simple and user-friendly device that offers a wide variety of functions.

The Smart Apnea features an apnea mode with characteristics specifically aimed at meeting the needs of freedivers.

The Smart Apnea computer can operate in monitoring mode or dive mode.

In monitoring mode, you can change the settings, check your logs with details such as dive duration and depth, download your data to your computer, and much more.

In dive mode, you can monitor the depth, time, descent and ascent rates, temperature, and other parameters that will be adjusted on the surface.

The Smart Apnea features a backlight function that is activated in low-light environments.

It can store dive profiles of approximately 20-30 hours, depending on the number of dives per session and the duration of each dive, assuming a 1-second sampling interval.

By using the USB clip (sold separately), the information can be transferred to a computer using the Dive Organizer software or to a Mac using the Divers' Diary software.
