GoPro sent me the new MISSION 1 PRO ahead of launch, and there was really only one way I wanted to test it.
Underwater.
Not in a pool. Not in perfect, controlled conditions. And not by simply reading through the spec sheet.
I wanted to know how it would actually behave on real dives, around real marine wildlife, where the light changes constantly, visibility is never guaranteed and the subject does not wait for you to get the shot.
So I took the MISSION 1 PRO diving around sharks, whale sharks, reef environments and blue-water wildlife to test the things that matter most to me underwater:
- Image quality
- Underwater colour
- Low-light performance
- Stabilisation
- Backscatter and difficult visibility
- Fast-moving wildlife
- Changing depth and changing light
- Real-world usability underwater
- Whether I would trust the camera in more serious filming situations
That last point is probably the most important.
A camera can have an impressive list of specifications, but when a wildlife encounter only lasts a few seconds, I care much more about whether I can trust it to capture something usable.
Disclosure: GoPro sent me the MISSION 1 PRO ahead of launch for testing. This review is based on using it underwater in the kind of wildlife conditions I normally work in.

If you want to see the footage for yourself, my full underwater test is embedded below. The video shows the camera in the actual conditions I used for this review rather than relying on manufacturer sample footage.
What Is Different About the GoPro MISSION 1 PRO?
The headline change is the move to a 50MP 1-inch sensor. For underwater work, that immediately caught my attention more than almost anything else on the spec sheet.
Underwater cameras are constantly fighting for light. The deeper you go, the less light you have available and the more colour disappears from the scene.
The MISSION 1 PRO also introduces much higher recording options than we traditionally associate with an action camera.
| Sensor | 50MP 1-inch sensor |
|---|---|
| Processor | GP3 |
| Maximum video | 8K60 |
| High frame rate | 4K240 and 1080p960 |
| Open Gate | 8K30 and 4K120 |
| Photo | Up to 50MP RAW |
| Colour | 10-bit recording with GP-Log2 options |
| Waterproofing | 20m / 66ft without a housing |
| Protective Housing | 60m / 196ft |
Those numbers are useful context, but they were not the point of my test.
The question was what happens when you actually take those specifications underwater.
Why I Wanted to Test It on Real Dives
Underwater filming is a very unforgiving test for a small camera.
Colour shifts with depth.
Light can change dramatically within seconds.
Suspended particles can create backscatter and reduce contrast.
Your subject may be moving quickly while you are also moving in the water.
And a scene that looks bright to your eyes can become surprisingly difficult for a small camera sensor.
That is why I wanted to use the MISSION 1 PRO around real marine life.
Sharks and whale sharks are particularly useful test subjects because they can move between bright surface water and darker blue water very quickly. They also do not give you the luxury of repeating the shot.
My testing included sharks, whale sharks, reef environments and blue-water conditions with changing light and visibility.
Underwater Image Quality
The first thing I look at with any action camera underwater is not simply sharpness.
I want to know what happens to the image when conditions become difficult.
Does fine detail survive?
Does the blue water still have natural gradation, or does it begin to look overly processed?
What happens when the animal moves from bright water into shade?
How much flexibility does the file give me once I begin correcting colour?
That is where the larger sensor becomes relevant.
The point of a 1-inch sensor underwater is not simply that it sounds better on a specification sheet. It gives the camera a stronger foundation when available light begins to drop.
In my review, I deliberately looked at footage from cleaner, brighter situations alongside darker and murkier wildlife encounters because that is a much more realistic picture of how the camera will actually be used.
Underwater Colour
Colour is one of the biggest challenges with any underwater camera.
As you descend, red wavelengths disappear first, followed by oranges and yellows. The deeper you go, the more the scene shifts towards blue or green.
That means I am not only interested in what the footage looks like straight out of camera.
I also care about how usable the file is once I begin correcting it.
The MISSION 1 PRO supports 10-bit recording and GP-Log2, which is relevant for anyone who wants to colour grade rather than simply accept an automatic look.
That is especially useful if you are trying to mix GoPro footage with material from a larger underwater camera in the same edit.
In the video review, underwater colour was one of the main things I paid attention to because it is often where small-camera footage begins to show its limitations.
Low-Light Performance
Low light underwater was another major part of my test.
This does not necessarily mean diving at night.
You can lose a surprising amount of light simply by descending a few metres, swimming beneath cloud cover or following an animal deeper into the water column.
That happens constantly with wildlife.
One moment a shark is close to the surface.
The next it drops into darker water.
Those changes are exactly where I wanted to see how the larger sensor coped.
I also included darker and murkier material in the review because perfect tropical visibility is not a very useful benchmark on its own.
Brighter water and darker, murkier conditions place very different demands on a small underwater camera.
Stabilisation With Moving Wildlife
Stabilisation matters a lot more underwater than people sometimes realise.
The animal may be moving.
You are moving.
Current and surge may be moving both of you.
And every fin kick or change in body position can translate directly into the camera.
So I wanted to see how the MISSION 1 PRO handled footage while actually swimming with wildlife rather than simply filming a static reef scene.
Good stabilisation is useful, but it is not a replacement for good underwater technique.
I still try to move slowly, minimise unnecessary finning and anticipate the animal's direction rather than chasing it.
Backscatter, Visibility and Difficult Water
Another thing that is easy to hide in a controlled review is backscatter.
Real water contains particles.
Sometimes a lot of them.
Those particles can reduce contrast and create a much softer-looking image, especially when visibility is poor.
I wanted the review to include those situations because they are part of real underwater filming.
A camera should not only be judged by the best clip you can produce from the best conditions.
The footage that interests me most is often what a camera does when the conditions stop being perfect.
8K60: Useful, but Not the Whole Story
The MISSION 1 PRO can record up to 8K60.
For wildlife, the obvious advantage is reframing.
You cannot ask a shark to swim half a metre closer.
You also should not chase an animal simply because you want a tighter shot.
Extra resolution gives you more room to crop in post while still delivering a high-resolution final image.
That can be genuinely useful.
But I would not choose a camera for underwater wildlife simply because the number on the box says 8K.
Colour, low-light behaviour, stabilisation and usability matter just as much — often more.
4K240 and Slow Motion for Wildlife
The camera can also record up to 4K240.
That is exciting for wildlife because very fast behaviour can become much easier to appreciate when slowed down.
Sharks turning, rays rolling and schools of fish changing direction can all happen faster than we perceive in real time.
But very high frame rates need light.
Underwater, that matters.
Just because the mode exists does not mean it is automatically the best choice at depth or in dark conditions.
Open Gate for YouTube and Vertical Content
Open Gate is one of the features that makes sense for the way I actually use footage.
A single wildlife encounter may eventually become:
- A horizontal YouTube sequence
- An Instagram Reel
- A TikTok
- A documentary clip
- A behind-the-scenes post
Recording more of the sensor gives you more flexibility to create those different crops later.
That does not remove the need to compose properly in the water, but it does make one encounter more adaptable in post-production.
Using the MISSION 1 PRO During a Real Dive
One of the most important things I was assessing was simply how practical the camera felt underwater.
During a dive, I am already thinking about:
- Buoyancy
- Depth
- My buddy
- The wildlife
- Animal behaviour
- Light direction
- Composition
- My surroundings
I do not want to spend the encounter digging through menus.
With a camera like this, I would much rather decide on the basic recording setup before entering the water and then keep the actual shooting process as simple as possible.
That real-world usability is just as relevant to me as the headline resolution.
Waterproofing and the Protective Housing
The MISSION 1 PRO is rated waterproof to 20 metres / 66 feet without an additional housing.
For snorkelling, freediving and shallow-water work, that gives you a lot of flexibility.
For deeper scuba diving, GoPro's Protective Housing extends that rating to 60 metres / 196 feet.
For me, a housing is also about more than depth.
Repeated saltwater use, dive boats, kit bags and travel can be hard on equipment, so additional physical protection can be useful even when the dive itself is relatively shallow.
Could I Trust It on a Serious Wildlife Shoot?
This was the standard I kept coming back to throughout the test.
Not:
Is this impressive for an action camera?
But:
If something genuinely special happens in front of me, do I trust the camera enough to use the footage?
That is a much harder test.
Wildlife filmmaking is full of moments you cannot recreate.
Sometimes you only get one pass.
Sometimes the animal disappears.
Sometimes the light changes before you get another opportunity.
So throughout my underwater review I was looking at the MISSION 1 PRO from that perspective rather than simply asking whether it produced a nice image in perfect conditions.
Where a GoPro Fits Beside My Main Underwater Camera
I normally work with a much larger underwater camera system, so I do not approach the MISSION 1 PRO as though it has to replace that entire setup.
A larger mirrorless system still gives me:
- Interchangeable lenses
- Dome-port options
- Dedicated macro lenses
- Strobe integration
- Much more optical control
- Greater flexibility for specialist shooting
But there are plenty of situations where carrying that entire system is not practical.
A camera this small can be useful as:
- A second underwater camera
- A behind-the-scenes camera
- A compact option for snorkelling or freediving
- An additional angle during wildlife encounters
- A travel camera when kit space is limited
That is the context in which I think an underwater GoPro review becomes more useful.
It is not simply about asking whether it can beat a completely different camera system.
It is about asking what jobs it can realistically do well.

What I Think Matters Most Before Buying One for Underwater Use
Look beyond the headline specs
- Think about the depths you normally dive
- Think about how often you work in low light
- Consider whether you actually need 8K
- Decide whether slow motion matters to your work
- Think about how much colour grading you want to do
- Factor in the Protective Housing for deeper scuba diving
Think about how you actually shoot
- Do you need something tiny beside a main rig?
- Are you mostly snorkelling or freediving?
- Do you create both horizontal and vertical content?
- Do you film fast wildlife behaviour?
- Will you use GP-Log2 and 10-bit footage?
- Do you want something simple enough to always carry?
GoPro MISSION 1 PRO Underwater FAQ
Is the GoPro MISSION 1 PRO waterproof?
Yes. The MISSION 1 PRO is rated waterproof to 20 metres / 66 feet without an additional housing.
How deep can the MISSION 1 PRO go with the Protective Housing?
GoPro's Protective Housing is rated to 60 metres / 196 feet.
Can the MISSION 1 PRO record 8K underwater?
Yes. The camera can record up to 8K60. Whether that is the best mode for a particular dive depends on the available light, required frame rate and how you plan to use the footage.
Can it shoot slow motion underwater?
Yes. The MISSION 1 PRO can record up to 4K240, with even higher frame-rate options at lower resolutions. High frame rates need more light, so they are most useful in brighter conditions.
Does the MISSION 1 PRO shoot RAW photos?
Yes. It can capture RAW still images at up to 50MP.
Is Open Gate useful underwater?
It can be particularly useful if the same wildlife encounter needs to be reframed for both horizontal and vertical edits later.
Is it a replacement for a professional mirrorless underwater system?
I see the two as different tools. A larger system offers far more control, lens choice and specialist options, while a GoPro offers a much smaller and simpler package that can be carried into situations where a full rig may be impractical.
Final Thoughts
What made this test interesting to me was not simply that GoPro had added a bigger sensor or more resolution.
It was seeing what those changes meant once the camera was actually underwater.
Real wildlife conditions expose weaknesses very quickly.
Light changes.
Colour changes.
Visibility changes.
Animals move.
And you do not get to repeat the moment because the camera was not ready.
That is why I wanted this review to be based around actual dives rather than idealised test footage.
The MISSION 1 PRO has an unusually ambitious specification for such a small camera, but the part that matters to me is how useful it can be when the ocean stops cooperating.
