Product Overview
The TELESIN Dome Port with Diving Stabilizer Kit is designed to enhance your underwater and over-under photography experience with GoPro Hero 9, 10, 11, and 12 cameras. This kit allows for simultaneous capture of images both above and below the water line, often referred to as half-and-half or split-level pictures. The included diving rig stabilizer provides a comfortable and stable grip, improving shooting stability during deep diving. It also offers rich expansion interfaces for additional photography equipment.
- Compatibility: The Dome Port is compatible with GoPro Hero 13/12/11/10/9. The Diving Rig Stabilizer is compatible with GoPro Max Hero 13 12 11 10 9 8 7 6 5 4, DJI Osmo Action, Action 2 3 4, Osmo Pocket 2 3, Insta360 X2 X3 GO2 GO3, other action cameras, SLRs, and also with GoPro waterproof cases and TELESIN Dome Ports.
- Optimal Size & Mounting: Measuring 322mm*237mm*53mm, the kit features dual hand grips for single or two-handed holding, enhancing stability and reducing effort. It includes two 1/4'' threads and three cold shoe mounts for attaching accessories like fill lights and magic arms.
- Detachable Design: Both the Dome Port and Diving Rig Stabilizer can be detached for separate use. Use them together for over/under water shots, or use the diving rig stabilizer with a waterproof case for full underwater use, or as a standalone handheld stabilizer.
- High-Quality Construction: Constructed from durable ABS+PC+Plexiglass. The German plexiglass dome provides 93% high light transmittance for vivid image capture. Lightweight ABS+PC handles reduce fatigue during extended use.

Setup
Follow these steps to set up your TELESIN Dome Port and Diving Stabilizer:
- Prepare the Dome Port: Ensure the Dome Port is clean and free of debris.
- Insert GoPro Camera: Carefully open the rear door of the Dome Port and insert your compatible GoPro Hero camera. Ensure it is seated correctly and securely.
- Check Seals: Before closing, thoroughly inspect the silicone ring around the camera housing for any debris, hair, or damage. A clean and intact seal is crucial for waterproof integrity.
- Secure the Camera: Close the rear door firmly, ensuring the waterproof button (if applicable) is properly aligned and engaged.
- Attach to Diving Rig: Align the mounting points of the Dome Port with the Universal Diving Rig. Use the provided long screw and mount adapter to securely fasten the Dome Port to the rig.
- Pre-Dive Check: Before actual use in water, perform a dry run or a shallow water test without the camera inside to confirm there are no leaks.

Operating Instructions
The TELESIN Dome Port and Diving Stabilizer offer versatile shooting options:
- Split-Level Photography (Over/Under Shots): To capture images both above and below the water simultaneously, hold the Dome Port so that the waterline intersects the middle of the dome. This technique is ideal for capturing unique perspectives of marine life and surface scenery.
- Underwater Photography: For fully submerged shots, ensure your GoPro camera is in its own waterproof case (if not already waterproof) before inserting it into the Dome Port. The Dome Port provides an additional layer of protection and optical clarity.
- Handheld Stabilizer Use: The Universal Diving Rig can be used independently as a handheld stabilizer for stable shooting in various environments, including underwater with a separate waterproof case for your camera.
- Accessory Mounting: Utilize the two 1/4'' threads and three cold shoe mounts on the diving rig to attach external accessories such as LED fill lights, microphones, or magic arms for expanded creative possibilities.

Maintenance
Proper maintenance ensures the longevity and performance of your kit:
- After Use: After each use, especially in saltwater, rinse the entire kit thoroughly with fresh water.
- Draining Water: The diving rig stabilizer is not waterproof and has drainage holes. After diving, tilt the product to ensure all water in the shell is completely drained.
- Drying: Allow all components to air dry completely before storage. Do not use heat to dry.
- Cleaning the Dome: Use the provided cleaning cloth or a soft, lint-free cloth to gently wipe the dome surface. Avoid abrasive materials that could scratch the plexiglass.
- Anti-Fog Inserts: Place the anti-fog film inserts inside the dome port as needed to prevent fogging in humid or cold conditions. Replace them when their effectiveness diminishes.
- Seal Inspection: Regularly inspect the silicone seals for any signs of wear, cracks, or deformation. Replace seals if necessary to maintain waterproof integrity.
Troubleshooting
Here are some common issues and their potential solutions:
- Water Leakage: If water enters the housing, immediately remove the camera. Check all seals and O-rings for proper seating, cleanliness, and any damage. Ensure the rear door is securely latched. Always perform a pre-dive water test without the camera.
- Fogging Inside Dome: This is often caused by temperature differences between the air inside the dome and the water. Use the provided anti-fog inserts. Ensure the camera and dome interior are completely dry before sealing.
- Unstable Footage: Ensure all mounting screws are tightened securely. Utilize both hand grips on the diving rig for maximum stability, especially in turbulent water.
- Difficulty with Buttons: Ensure the camera is correctly positioned within the housing and that the housing's buttons align with the camera's controls.
