Sphera mask's?

Thread Status: Hello , There was no answer in this thread for more than 90 days.
It can take a long time to get an up-to-date response or contact with relevant users.
Also the lenses are made of plastic which from what I've heard makes things appear more realistic in terms of size. Glass lenses tend to make things look bigger than they actually are.
 
They compress very easily in comparison to glass mask so need very little EQ, especially for deep stuff.

Cons are that the plastic lenses get scratched and severly distort images at depth, much worse than a glass mask. All that is perfectly fine for line diving but not spearfishing.
 
Agreed, super easy to equalize even compared to a decently low volume spearfishing mask. Fogging is also an issue with a plastic lens. I use one for line diving but not for spearfishing.
