Underwater WiFi Extension Cable for Action Cameras
We have limited stock of our our legacy GoPro BacPac Dive Housing model of the Underwater WiFi Extension Cable for use with the HERO3 and HERO4 cameras only. It must be used with the GoPro Dive Housing rated to a depth of 60m (196ft). Select the "H3/H4 only models in the dropdown". See more information on the legacy product here.
The Underwater WiFi Extension Cable is compatible with various action camera housings and clips to the "2pin action camera pivot mount" of a waterproof camera housing.

Any wifi enabled action cam with the 2 pin action camera pivot mount
The Underwater WiFi Cable extends the 2.4 GHz WiFi and Bluetooth signal above the water to allow you to perform any function that you can normally do using these signals, such as viewing a live preview using the GoPro App, YI Action App, SJCAM App, or Apps for other WiFi enabled cameras.
The wet end of the link has a custom pivot mount that attaches to many standard action waterproof action camera housings (the housing is not included). The clip connects to the standard 2pin pivot mount for action camera housings. Just turn on the camera WiFi, close the waterproof camera mount, adjust the wet end clip to be pressed against the back of the camera, and drop the camera into the water. No connection to the camera is necessary. The interface to the camera is wireless.
At the dry end, the WiFi Extension Cable interfaces wirelessly with any wireless device such as an Android phone or tablet or iPhone or iPad or the GoPro WiFi Remote. The GoPro App or similar software provides real time video monitoring and complete control over the camera settings.
wifiEnables WiFi and Bluetooth underwater
2.4 GHz WiFi and Bluetooth signals are extended above water to allow you to control your Action camera in any way you normally would using the Bluetooth or WiFi signal.
The wet end of the WiFi Extension Cable clips to the waterproof Action Camera Housing.
sortMultiple cable lengths available
We offer many lengths ranging from 20 to 300 feet so you can get the appropriate cable to suit your needs.
An inline connector near the dry end makes it possible to detach the dry end to thread the cable through a protective pipe or handheld pole.

Frequently Asked Questions
How do I adjust the wet-end antenna to fit my camera's housing model?
The wet-end is connected to the standard 2pin action camera pivot mounting system. The attachment of the mounting knuckle to the wet-end antenna is slotted with two screws that allow the wet-end antenna to be adjusted to fit tightly against the back of the camera housing for optimal signal transmission.
To adjust the position, loosen the two screws at the base of the wet-end antenna as well as the thumbscrew. Pivot the antenna to the back of the camera and slide the antenna so that it is flat with the back of the camera housing before tightening the two knuckle screws.
What is the maximum cable length possible?
We have tested cables to 100 meters (328 feet) with excellent results using a Nexus 5 as the controller. As the cable gets longer, the signal will be weaker and results will depend on the presence of interfering signals and the quality of the antenna in the controlling device.
What is the maximum depth?
The maximum depth will depend on the waterproof rating of the camera or housing. For example, the GoPro Dive Housing is rated to a depth of 60 meters, while the GoPro HERO5 through HERO7 cameras are waterproof up to 10meters without an added waterproof housing. When using a waterproof housing, we strongly recommend you test the housing with no camera every time before inserting the camera. A small scratch, dirt, grease or hair can be enough to allow water in.
How far can the tablet or phone be from the dry-end antenna?
It depends on the cable length, orientation of the dry-end antenna, the type of the antenna in the controlling device, and the interference from other signals. It will work for a few feet in most cases, but the closer the better.
What WiFi frequency does the cable work with?
2.4 GHz. The cable is not compatible with 5 GHz. On HERO 7 / HERO 6 / Fusion cameras, make sure to select 2.4 GHz in the wifi settings menu (earlier model cameras auto switch). Refer to this GoPro support article for more information.
How do I determine the best orientation for the adapter relative to my phone/tablet?
There are many apps available that show the changes in WiFi signal strength as the dry-end antenna moved. We use WiFi Analyzer.
How do I attach the dry end to the monitoring device?
Is your cable compatible with the Hero 8 / 9 housing, that has a bump at the back?
Yes, the cable does work with the Hero 9.
Note, the wet-end must be tight against the back of the camera/housing for reliable signal transmission to the antenna. The cable is designed to work with the HERO8/9 without a housing since these cameras are waterproof and have the two-pin mount incorporated.
The cable also fits the standard GoPro housing for the HERO5/6/7 which while waterproof, requires the housing for the mounting point. If using a camera housing with an extended back, a spacer can be used to accommodate the additional depth required for the wet-end antenna to lay flat with the back of the housing.
What have people used your WiFi Extender for?
An example of the Underwater WiFi Extender in action:
A HERO3 camera attached to a 15 foot fiberglass Bream pole using a handlebar mount is being used to do a hull inspection of this sailboat. A golf ball retriever also makes a good extendable pole for mounting the camera. The video preview allows the user to select snapshots and take short close up videos of delamination, osmosis damage, algae growth or barnacles.
What do your customers say?
Just want to send you guys my sincere thanks for providing the Go-pro wifi extender equipment last weekend, we successfully spotted the DJI Phantom drone that was lost in a lake with 10 inch visibility and equipment worked flawlessly underwater!
Thanks So Much! -MB
