Honestly I haven't tested it for depth. The weather is still cooler, so I've only tested in the bath so far, and the Hero 9 itself is waterproof and rated to several feet. Other than that, it really seals the Hero 9 and covers and covers it completely. I love that it has external mounting legs. I was able to attach a floating orange stick to it, so I'm not trying to figure out how easy it is to hold the GoPro for shots. Anti-fog wipes are a nice touch. I plan to do a full test at multiple water sites this summer. I will update later.
