The measurement of the diving masks Internal Volume by Apneapassion is 100% “certified” as the Field of View, precise, repeatable and comparable. Each mask is mounted on a dummy head with all parameters kept unvaried. Using a graduated siringe water is injected in the mask until all the internal volume is filled. The final result indicates how much water has entered the mask before leaking out of it upper profile. Below are the updated standings of all the masks that we have certified as of today, so that you can compare the Internal Volume of every model of every brand to the other.

The Internal Volume is a very important parameter, especially in freediving and deep spearfishing, but of course also scuba diving. Still, it is clear that the most important aspects of a mask remain the comfort and perfect water seal.

Below the chart with the best masks in order from the smallest to the greater internal volume. With mobile phones turn the phone horizontally for a better view of the chart!

* In the videos at the links, the water lost at the end of the measurement is similar for all masks and unavoidable. The water present inside the tube at the end of the measurement compensates for the volume occupied by the tube inside the mask.
