The wet end of the link is a custom backdoor which clips to the GoPro Housings (the housing is not included). Our 20ft to 125ft lengths are molded into a GoPro Standard Housing backdoor that is rated to a depth of 40m (131ft). For use at greater depths, our longer lengths are molded into a backdoor that fits the GoPro Dive Housing rated to a depth of 60m (196ft). Just turn on the camera WiFi, close the back of the housing, 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 to provide real time video monitoring and complete control over the camera settings.

Disclaimer: As with regular GoPro waterproof housings, it is prudent to test the housing underwater before putting your camera in every time you use it. Our warranty does not cover incidental damage. Always keep the O-ring and edges of the case clean. Always inspect them before every use. Do not use silicone or other grease on the O-ring.

Frequently Asked Questions

How do I replace the standard backdoor with the wet end of the Underwater WiFi Extension Cable?

The standard backdoor of the GoPro Housing can be removed and replaced with the wet end of the Underwater WiFi Extension Cable. If you look at the bottom of the hinge holding the backdoor to the front of the housing, you should notice that it is slotted. The backdoor of the GoPro housing snaps off of the camera housing if you open the backdoor all the way and rotate or pull the backdoor downward. No tools are required. This video shows how to easily unclip the standard backdoor from the GoPro Housing: https://www.youtube.com/watch?v=zghMZyiwqYs

How do I tell if I have a GoPro Dive Housing or Standard GoPro Housing?

All GoPro HERO3 and HERO4 cameras currently ship with the Standard Housing, which is slightly smaller than the Dive Housing and fits of 12ft to 125ft lengths of Underwater WiFi Extension Cable. Our cable lengths of 150ft and above do not fit the Standard Housing and require a Dive Housing.

Please compare your camera housing to these pictures to ensure you have what you need for your project.

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?

Our longer lengths of Underwater WiFi Extension Cable fit the GoPro Dive Housing which GoPro rates to a depth of 60 meters. We strongly recommend you test the housing and backpack with no camera every time you use it. A small scratch, dirt, grease or hair can be enough to allow water in. Stress may have affected the cable or the exit point. We do not test each backpack before shipping and do not know the maximum depth before failure for your unit.

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.

How do I determine the best orientation for the adapter relative to my phone?

There are many apps available that show the WiFi signal strength. We use WiFi Analyzer.

How do I attach the dry end to the monitoring device?

The dry end interface can be attached to the back of the phone or tablet using velcro or 3M double sided removable mounting squares.

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 flawless under water!

Thanks So Much! -MB
