B1 - Optics

The Google Pixel 9 Pro XL excels in its image processing capabilities. Google has always been ahead in this area. Underwater, and in natural light, this translates into surprisingly accurate colors. The algorithms effectively compensate for the loss of red. You get vibrant shots, even without a red filter. Sharpness is also excellent. Details of corals or fish are well captured. Video Boost is a major advantage. It improves the dynamic range and colorimetry of underwater videos. This is a real plus for the final quality of your films.

For more details: The Google Pixel 9 Pro XL features the Tensor G4 processor. This processor is optimized for advanced image processing and artificial intelligence. It enables real-time adjustments for improved color and light reproduction.

B2 - RAW

The ability to shoot in RAW format is available. This is what matters to demanding photographers. The RAW file offers significant editing latitude. You can correct the white balance. You can adjust the exposure. This allows you to recover information from highlights and shadows. This is an advantage for refining your images after the dive. The internal processing of the Pixel is already very good. But RAW gives you complete control. It's an option not to be overlooked.

B3 - Storage

Storage is a key feature. The Google Pixel 9 Pro XL is equipped with a USB 3.2 port (10 Gbps). It's fast. Very fast. Transferring a full card of photos and videos after a day of diving takes only a few minutes. Wi-Fi 7 is also included. This makes wireless transfers easier. You can quickly back up your photos to the cloud or a NAS. This is a welcome convenience, especially when you have a lot of data to manage. A silica gel pack is mandatory for the phone. It provides protection against moisture. The aluminum and glass body make it susceptible to condensation.

For more details: The USB 3.2 (10 Gbps) port on the Google Pixel 9 Pro XL ensures high transfer speeds. It's ten times faster than USB 2.0. Wi-Fi 7 offers improved wireless performance. It's ideal for fast backups.

B4 - Thermal

The thermal management is good. The Tensor G4 is efficient. We haven't observed any significant overheating. Even during long video sessions. This is important underwater. A phone that gets too hot can slow down. It may even shut down. The Pixel 9 Pro XL maintains stable performance. This is reassuring for your dives. You can focus on taking pictures, not on the device's temperature.

B5 - Battery

The battery life is decent. The Google Pixel 9 Pro XL lasts for a day of three dives. This is with moderate use. If you are filming a lot, consider bringing an external battery pack.

B6 - Autofocus

The autofocus is responsive. That's what matters underwater. Moving subjects are tracked well. The focus is precise, even in low-light conditions. The Pixel 9 Pro XL handles contrast well. It quickly locks onto the subject. This is an advantage for wildlife photography. You won't miss that crucial moment. The speed of the autofocus is a guarantee of success.

B7 - Enclosure

The case is a fundamental element. For the Google Pixel 9 Pro XL, the Divevolk SeaTouch 4 Max is the obvious choice. It is robust. It is reliable. The ergonomics are excellent. You can easily access the phone's functions. The touchscreen remains usable. This is a proven solution. It effectively protects your device. It provides peace of mind. You can dive with confidence.

The safety of your equipment depends on it. Do not take any risks.
