The KNEKT semi-hemispherical 6" dome port is one of the most advanced accessories available for the GoPro. 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. Until now one would need to invest thousands of dollars in high-end camera equipment in order to create these images. And even with the best gear producing quality results would be a challenge due to the complexity of focus, exposure and depth of field management. The KSD6 paired with the GoPro overcomes all of this. The simplicity of operation, nearly infinite depth of field, wide-angle lens and video and still image quality make the GoPro perfectly suited for this application. Just slide the KSD6 Dome Port onto the GoPro housing, turn it on and produce stunning imagery. The KSD6 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. By utilizing an interlocking two-piece design the dome is captured mechanically to create an O-ring compression seal, no glue or silicone is used anywhere. This design allows the dome to be fully disassembled for cleaning and service. The KSD6 works with the Hero3+ or Hero4 housing and does not require any special modifications or separate accessories. The GoPro is just as secure as always since the KSD6 slips right onto the housing, it does not alter the depth rating of the GoPro housing. The KSD6 provides access to mode, power and shutter control buttons while installed. The built in front LCD window allows the user to see battery life, camera settings and memory card data.
