The standard configuration is supplied for the camera model selected when ordering. Please select or specify your exact GoPro model before completing the order.
HERO8 notice: The HERO8 configuration requires additional components and an additional $26 charge. These components are not sold separately.
Media Mod Required
A compatible GoPro Media Mod is required to provide the HDMI output used by the DNC-GP17. The GoPro camera and Media Mod are not included with the standard system.
Before ordering, confirm that a compatible Media Mod is available for your selected GoPro model.

HDMI Live View and Internal Recording
The DNC-GP17 provides a live HDMI signal to the surface at up to 1080p60. This live output can be viewed on a compatible HDMI display or sent to a recorder, capture device, or streaming system.
The GoPro can also record video to its internal memory card. Available internal recording resolutions and frame rates depend on the installed GoPro model, camera settings, firmware, and operating conditions. Internal recording resolution should not be confused with the 1080p60 surface HDMI output.

Frequently Asked Questions
Does the DNC-GP17 include a GoPro camera?
No. The GoPro camera must be purchased separately.
Is the GoPro Media Mod included?
No. A compatible GoPro Media Mod is required for HDMI output but is not included with the standard DNC-GP17 system.
Does the system output 5K video through HDMI?
No. The live surface HDMI output is up to 1080p60. Higher-resolution recording may be available internally on the GoPro memory card depending on the installed camera model and settings.
Can the GoPro operate continuously?
The included 45 m power cable supplies power from the surface, allowing extended operation without relying only on the GoPro's internal battery. Actual operating time depends on the camera, power source, settings, temperature, and recording conditions.
Can I connect the system directly to a television or monitor?
Yes. The surface end of the HDMI cable uses a standard full-size HDMI Type A connector. The connected display or recorder must support the GoPro's HDMI output format.
Can I stream directly to an iPhone?
An additional compatible HDMI capture or iPhone monitoring adapter is required. The adapter is optional and is not included with the standard system.
Can the system be used at a depth of 100 meters?
The housing is rated to 100 m (328 ft), but the supplied HDMI and power cables are 45 m (147 ft) long and the included LED light is rated to 45 m. Therefore, the standard complete configuration is intended for deployments up to 45 m.
Important Before Underwater Use
- Select the correct housing configuration for your GoPro model.
- Confirm that the GoPro and Media Mod operate correctly before installation.
- Inspect and clean both O-rings before every deployment.
- Confirm that the housing is fully closed and correctly sealed.
- Test the live HDMI image and surface power before entering the water.
- Secure both surface cables to prevent excessive pulling on the housing.
- Do not exceed the rating of the lowest-rated component in the complete setup.
Ordering notice: Please specify the exact GoPro model you intend to use. The housing is configured for the selected camera before shipment.
