Moving the waterline away from the lens makes it possible to capture images both above and below the water simultaneously

These are often referred to as half and half, 50/50, over under or split-level pictures

Easy to operate, nearly infinite depth of field, wide-angle lens and video and still image quality

The Dome Port utilizes a custom made semi-hemispherical acrylic dome that has been optically matched to work with the GoPro lens

The use of a semi-hemispherical dome eliminates the perpendicular angle between the backing plate and the dome. The benefits of this are the elimination of circular reflection and improved water sheeting while reducing the form factor and maintaining full front face surface area. 

The side of the base has 12 screws, this design allows the dome to be fully disassembled for cleaning and service

The pistol trigger shutter is designed to work with most of floating bobber handle models in the current market

One-handed operation, split structure

Compatible with GoPro Hero 6/5
