## Summary description

Underwater dome port case Telesin GP-DMP-T09 is designed for use with GoPro Hero 9. The dome shape improves wide-angle and horizon separation underwater, enabling clearer split-level (above/below water) shots and reduced distortion at the waterline. It protects the camera in wet environments and is intended for snorkeling, diving, surf and other water sports where improved image composition and protection are needed.

## Long description

Underwater Dome Port Case Telesin for GoPro Hero 9 (model GP-DMP-T09) is a waterproof dome accessory designed to improve split-level and wide-angle imaging when using a GoPro Hero 9 in wet environments. The dome shape displaces the waterline away from the camera lens, reducing optical distortion at the horizon and enabling clearer above-and-below water composition. The case also provides a protective housing for snorkeling, diving, surfing and other water-based activities where the camera requires both protection and enhanced image separation.
Advantages
The dome port enhances the field of view by moving the waterline away from the lens plane, which reduces refraction-related distortion and helps produce sharper split-level photos and videos. The accessory is built to fit the GoPro Hero 9 form factor, offering easy attachment and reliable sealing in wet conditions. Its dome geometry improves horizon alignment and the visual transition between air and water, while also protecting the camera from splashes and contact with debris.
Suitable for
Snorkeling and shallow diving where split-level shots are desired
Surfing, paddleboarding and other surface water sports
Coastal photography to capture both underwater details and sky/horizon
Pool shoots and recreational water activities that require lens protection
Key specifications
Compatibility: Designed for use with GoPro Hero 9 camera body and lens alignment
Optical element: Dome-shaped port to reduce refraction and horizon distortion
Material: Rigid, water-resistant housing materials suitable for contact with water
Sealing: Mechanical seal/interface intended to keep the camera protected from splashes and surface water
Use environment: Suitable for saltwater and freshwater surface use; not a substitute for deep submergence housings rated for extended deep diving
How to use
Align the GoPro Hero 9 with the internal mounting position inside the dome port and secure it according to the accessory's attachment system to ensure a water-tight connection. Verify that the sealing surfaces are clean and free of sand or debris before closing. Enter the water slowly and keep the dome oriented so the waterline crosses the dome at a suitable point for split-level composition. After use, rinse the dome port with fresh water to remove salt and particulate matter, then open and dry all sealing surfaces thoroughly before storage.
Usage recommendations
For best split-level results, use the dome port in calm or moderately choppy water and position the camera at a slight angle to the surface to frame both underwater subjects and sky. Avoid deep submersion beyond the accessory's intended use; follow routine inspection and maintenance of seals and mounting points to ensure continued protective performance.
