How to choose a dive mask:

1 ) Seal test : Hold the mask in place with a small breathe intake. Aims to test the fit of the mask
2 ) single pane = more front view but less side view
double pane = more left to right vision
For photography, choose low volume, double pane with black silicon skirting
Note about purge valve:
Some diving masks have purge valves that allow elimination of water without breaking the seal. Purge valves are one-way valves, usually integrated into the mask right under the nose, and let you get rid of water by snorting into the mask. Wearers of contact lenses often prefer purge valves because taking off the mask under water may result in the loss of a lens. Some experienced divers contend that a purge valve is not necessary and simply adds cost and complexity. And masks with purge valves are typically higher volume, so the larger amount of water that needs to be eliminated during the clearing process offsets the usefulness of the purge. Finally, a purge valve mask is rendered useless without the tiny silicone diaphragm in the purge, so bring along spares! The mask shown on the right is an Oceanic Ion 2 Purge.
