The Insta360 Ace Pro 2 is pushing the boundaries of what an action camera can do. With dual imaging chips, a Leica lens, 8K filming capabilities, and a massive 50MP photo resolution, this camera delivers some of the most cinematic footage available in a pocket-sized form. But is it practical for scuba diving, or does it lean too far into professional filmmaking?

We tested the Ace Pro 2 across different conditions—from bright coral reefs to murky low-light wrecks—to see how well it performs as a diving camera. Does it stand out among competitors like the GoPro Hero 13 Black and DJI Osmo Action 5? Let’s find out.

About this review

To help you find a Underwater Action Camera that will fit your needs, we’ve tested, researched, and reviewed the best ones available today.
We test both in the water, diving in various conditions - and in our lab - so we can give you accurate answers on quality, performance, and the overall value.

Things we like:

  • Can film up to 8K
  • The rear screen can flip-up for selfie mode
  • Produces great footage in a range of scenarios

Things we don't like:

  • The front screen is matrix only, so no selfie screen when in a dive case
  • Prone to overheating when filming in 8K

Initial thoughts and unboxing

The Ace Pro 2 is built with high-end imaging in mind. The dual-chip processing sets it apart from every other action camera on the market, ensuring smoother low-light performance, better noise reduction, and AI-enhanced stabilization. The Leica lens further improves clarity and sharpness, especially in challenging lighting conditions.

One standout feature is the flip-up rear touchscreen, which makes framing shots easier, especially when filming yourself. However, the front screen lacks a live preview, which is a drawback for vloggers and divers using a housing.

Test results: How does it perform underwater?

Color accuracy and exposure balance

Video

The Ace Pro 2’s Leica lens and dual imaging chips help it produce natural and accurate color balance underwater. Unlike some competitors that oversaturate blues or reds, the Ace Pro 2 retains realistic tones, particularly in well-lit conditions.


White objects like sand and fins don’t get overexposed, and darker subjects like coral shadows hold detail well.


Stabilization and motion handling

Video

The AI-powered stabilization ensures smooth video, but it’s not as refined as GoPro’s HyperSmooth 6.0 or DJI’s RockSteady 3.0. Fast movements underwater can cause minor jitters, but for standard diving conditions, the stabilization is excellent.


Low-light and murky water performance

Video

The Ace Pro 2 performs exceptionally well in low light compared to its competitors. Its larger sensor and dual imaging chips allow it to capture details in shadows that GoPro and DJI struggle with. This makes it ideal for wreck diving or deeper reefs where natural light is minimal.


Depth rating and diving suitability

Video

The biggest downside of the Ace Pro 2 is its limited depth rating of 39 feet (12 m) without a housing. For snorkelers, paddleboarders, and free divers, this is fine, but scuba divers will require a dive case. With the official Insta360 housing, it can reach 196 feet (60 m), making it suitable for deep dives.


Accessories: what you’ll need for diving

While the Ace Pro 2 excels in video quality, divers will still need a few extra accessories:

  • Insta360 Dive Case: essential for diving beyond 39 feet (12 m)
  • Floating hand grip or tray: helps stabilize footage while filming underwater
  • Red or magenta filter: helps correct underwater color loss
  • Extra storage cards: 8K footage takes up massive amounts of space

Price/Quality Ratio

At just under $500, the Insta360 Ace Pro 2 is one of the most expensive action cameras on the market. However, it delivers industry-leading imaging performance, making it worth the price for filmmakers and content creators who need top-tier video quality.

For divers, however, the additional cost of a dive case and lack of built-in underwater features make it a less compelling choice compared to the DJI Osmo Action 5 or GoPro HERO13.

Do we recommend the Insta360 Ace Pro 2?

Yes, if you’re looking for the absolute best action camera for video quality. The Ace Pro 2’s 8K capabilities, Leica lens, and AI-powered processing make it the most cinematic action camera available today.

However, if you’re primarily a scuba diver, you might find better value in the GoPro HERO13 Black or DJI Osmo Action 5, which offer stronger underwater-specific features and built-in dive capabilities. If 8K filming isn’t a necessity, there are more practical choices for divers.

For filmmakers and professional content creators, though, the Insta360 Ace Pro 2 is a groundbreaking camera that sets a new standard in action cinematography.
