Special Snorkling 2D / 3D Underwater Mount

With this very cheap, GoPro compatible mount,
you will be able to film during a long time
almost as if you were diving at a couple of meter below the surface !

      

"Pizza" plate adds a lot of stability !

Dual Hero System

   

 

Here a special screw, GoPro like, had been designed and the knob has been removed from its original hole and reset on the other side. BTW, it shcould be glued there now ...
