Hello everybody
The people from the norwegian spearfishing shop Frivannsliv have measured the horizontal/vertical viewfield and the volume of several masks.

I thought it might be interesting:)
I apologize for not being a very active member otherwise..:nono: Anyhow I do have some interesting footage from my recent trip to Norway, I will sum it up and post it soon.
Safe and happy diving

Hello Isaak,
You performed very interesting test, congratulations for that. I red it thanks to Google translation, but I'm afrraid not everything is clear for me and I have some questions.
What about the distance between mask and measuring ruler (red arrow)?
For the tables. As far as I understand first table is for viewing angles (horisontal, vertical and total) (in mm) and the second table is for volume (in ml), but I'm surprising the figures in the two tables are absolutely the same. Please check once again isn't it a mistake.
