The Vented Accessory Backdoor is a deeper backdoor than the original flat backdoor . It is compatible with the Alti-Force Sensor Pack and fits GoPro® standard housings shipped with Hero3+ and Hero4 cameras (does not fit the larger Hero3 case). The Vented Accessory Backdoor is a standard GoPro backdoor that has been modified by replacing the button with a Water-resistant Air Vent.
The Water-resistant Air Vent is used for air pressure equalization of a GoPro waterproof camera case. The vent uses advanced technology to allow air to pass through while blocking water penetration to a depth of 1 meter (~3 feet).
Benefits of the Vented Accessory Backdoor:
- Pressure equalization to prevent that hard-to-open case after altitude or temperature changes seal it shut.
- Compatiblity with the Alti-Force Sensor Pack‘s altitude feature.
- Pressure/altitude measurement smoothing in turbulent air.
Add one of these to your Alti-Force order for quick assembly.
Also available: Water-resistant Air Vent with instructions to modify your own case.
