The Seeker mask was designed with two main objectives: maximise the diver&&';;s field of vision to be as close as possible to the experience of not wearing a mask using a single lens and to fit everyone - well, nearly everyone. New facial geometry was combined with a soft silicone skirt to provide an outstanding and comfortable fit. The low volume design allows easy equalization and mask clearing as well as creating a visual experience which is wider and brighter than ever before - with a near natural field of vision.
