Technisub Sphera mask

[Hennie]

Would like to hear if anybody out there have had any problems with this mask beyond 45m, leaking, mask squeeze?

Are there any similiar masks out there like the Sphera?

Herbert Nitsche used his to 89m....

i find i can control mask equalisation more precisely with standard freediving masks like the Target (and its clones). I've been using the Sphera for a few months now and it's taken a bit of getting used to but it is better, because the lenses flex.
I've found that i have to shave before using it... having some stuble makes it leak a lot, for me anyway!
also, i've found that i can equalise it better and it generally fits better if i position it a little lower on my face - try wearing it just a few millimeters lower. for me it's makes a big difference.
also don't let it squeeze too much. again, for me, if i leave equalisation too long, then i find it hard to equalise it, or sometimes i can only equalise one side of the mask!
hope that's useful

I used to dive with my Cressi Occhio and one of the first things is realized on my first dive with the Sphera was less mask squeeze, better visibility, easier equalizing.

I also have to make sure i shave before i dive otherwise i turn my Sphera into a fluid mask.

Tried once to spear with it but the Occhio is still better for that purpose.
