Why I Chose the Yi Action Camera Waterproof Case Kit

Let me tell you a story. Last summer, I took my Yi Action Camera on a snorkeling trip in the Philippines. I was so excited to capture the vibrant coral reefs and tropical fish—until I realized my camera wasn’t fully protected. I had a cheap, generic case that leaked after just 10 minutes underwater. The result? A foggy lens, water droplets on the sensor, and zero usable footage. That’s when I decided it was time to invest in a reliable solution: the Yi Action Camera Waterproof Case Kit.

Since then, this case has been my go-to companion for everything from kayaking to scuba diving. Whether you’re a weekend warrior or a full-time content creator, protecting your action camera is non-negotiable. The Yi Waterproof Case Kit promises to be the ultimate shield against water, dust, and impacts—but does it deliver? After months of real-world testing, I’m here to share my honest take. From build quality to underwater performance, I’ll cover everything you need to know before hitting “buy.”

What’s Included in the Yi Action Camera Waterproof Case Kit?

Unboxing the Kit: What You Get

When I first opened the box, I was pleasantly surprised by how thoughtfully the kit is packed. It’s not just a case—it’s a full ecosystem for underwater shooting. Here’s what you get:

• Yi Waterproof Housing: The star of the show. Made from high-strength polycarbonate with a silicone O-ring seal.
• Standard and Diving Backdoors: Two interchangeable backdoors—one for surface use, one for deeper dives.
• Anti-Fog Inserts: Pre-cut desiccant pads to prevent condensation inside the case.
• Quick-Release Mount: Lets you attach the case to helmets, handlebars, or tripods.
• Lens Cap: A protective cap for the front of the housing.
• User Manual & Cleaning Cloth: Simple instructions and a microfiber cloth for lens care.

I appreciated that everything fits neatly into a compact, reusable storage box. It’s perfect for tossing into a backpack or dive bag without worrying about loose parts.

Compatibility: Which Yi Cameras Work?

The kit is designed for the Yi 4K Action Camera and Yi 4K+. If you own an older Yi Lite or 1080p model, double-check compatibility—some parts may not fit perfectly. I tested it with my Yi 4K+, and the fit was snug with no wobbling. The buttons align perfectly, and the touchscreen remains responsive through the case.

One small caveat: if you use a wide-angle lens attachment, the front of the case might interfere slightly. I noticed a tiny vignette in my ultra-wide shots, but it was easy to crop out in post. For most users, this won’t be an issue.

Build Quality and Design: Built for the Wild

Materials That Withstand the Elements

The housing is made from reinforced polycarbonate—the same stuff used in riot shields and bulletproof glass. I’ve dropped it from waist height onto rocks, sand, and even concrete, and it didn’t crack or scratch. The hinges are metal, not flimsy plastic, which gives me confidence in its longevity.

The silicone O-ring seal is thick and pliable. After months of use, it shows zero signs of drying or cracking. I’ve seen cheaper cases where the seal degrades after a few dives, but Yi’s feels premium. The case also has a double-locking mechanism—a primary latch and a secondary safety catch. This prevents accidental openings, which is crucial when you’re 30 feet underwater.

Ergonomics and Usability

The case is surprisingly lightweight (about 180 grams) and doesn’t add much bulk to your camera. The buttons on the side are large and textured, making them easy to press even with gloves on. I’ve used it in cold water (around 15°C/60°F) with 3mm neoprene gloves, and the buttons responded instantly.

The touchscreen works through the case, but it’s slightly less responsive. You’ll need to press a bit harder than usual. For quick settings changes (like switching from 4K to 1080p), it’s fine. But if you’re editing footage or adjusting complex settings, I recommend doing that before sealing the camera.

Ventilation and Anti-Fog System

Nothing ruins underwater footage faster than fog. Yi tackles this with pre-installed anti-fog inserts that absorb moisture. I’ve used the kit in tropical humidity (85%+) and cold mountain lakes, and I’ve never had fog issues. Pro tip: replace the inserts every 3-5 dives, or whenever they feel damp. You can buy replacements online for a few dollars.

The case also has tiny ventilation channels near the lens. These let air escape during dives, preventing pressure buildup. I tested this by submerging the case in a pool and watching the bubbles—it’s a small detail, but it works.

Underwater Performance: Dive Deep, Shoot Clear

Depth Rating: How Far Can You Go?

The kit is rated for 40 meters (130 feet), which covers most recreational diving and snorkeling. I took it to 35 meters during a dive in Palau, and it performed flawlessly. The pressure seal held, and the camera recorded crisp 4K footage of manta rays and reef sharks.

For context, most scuba divers stay within 30 meters. The 40m rating gives you a safety buffer, which I appreciate. That said, if you’re a technical diver (40m+), you’ll need a specialized housing. This case isn’t designed for extreme depths.

Image and Video Quality Underwater

Underwater colors tend to shift (reds disappear first), but the Yi camera’s built-in color correction helps. The case’s flat glass lens preserves image sharpness. I compared shots taken with and without the case, and the difference was minimal. The only noticeable change was a slight reduction in low-light performance due to the glass thickness—but that’s true of all waterproof cases.

One thing I loved: the case’s anti-reflective coating. Sunlight reflecting off the glass is a common issue, but Yi’s coating minimizes glare. I got stunning shots of coral reefs at noon, with no annoying sunspots.

Real-World Test: Snorkeling, Kayaking, and Surfing

I’ve used the kit in three different environments:

• Snorkeling (0-5m): The camera stayed dry, and the anti-fog inserts kept the lens clear. I captured a sea turtle gliding past—no leaks, no fog.
• Kayaking (splash protection): The case shrugged off waves and rain. The quick-release mount held firm even when I capsized.
• Surfing (saltwater exposure): After a session in the Pacific, I rinsed the case with fresh water. No corrosion, no salt buildup.

The only hiccup? Sand. On a beach in Bali, sand got into the latch mechanism. I had to rinse it thoroughly to avoid scratching the O-ring. Lesson learned: always rinse with fresh water after saltwater use, and check the seals for debris.

Accessories and Mounting: Flexibility for Every Adventure

Quick-Release Mount: Versatile and Secure

The included mount is a game-changer. It’s compatible with GoPro-style accessories, so you can use it with your existing gear. I’ve attached it to:

• A chest harness for kayaking.
• A helmet mount for mountain biking.
• A tripod for time-lapse videos.

The mount clicks into place with a satisfying “snap,” and the release button is easy to find with one hand. I’ve never had it come loose during intense activity.

Optional Upgrades: What You Might Need

While the kit is comprehensive, a few extras can enhance your experience:

• Extra Anti-Fog Inserts: Keep a pack in your dive bag.
• Neoprene Floaty Backdoor: Prevents the camera from sinking if you drop it. (Yi sells this separately.)
• External Microphone Adapter: For vlog-style audio. (Note: audio quality is muffled when the camera is in the case.)

I wish Yi included a floaty backdoor by default—it’s a $20 add-on. For the price, I’d expect it to be part of the kit.

Storage and Transport

The storage box is a nice touch, but it’s not waterproof. If you’re traveling to a rainy destination, consider a dry bag. The case itself is compact enough to fit in a small camera pouch. I’ve carried it in my carry-on luggage for flights, and it passed security checks without issues.

Pros, Cons, and the Verdict: Is It Worth It?

The Good: What I Loved

• Reliable waterproofing: 40m depth rating with zero leaks in my testing.
• Durable build: Survived drops, saltwater, and sand.
• Anti-fog system: Kept my lens clear in humid and cold conditions.
• GoPro-compatible mount: Works with existing accessories.
• Lightweight and compact: Doesn’t weigh down your gear.

For the price (around $50-$70), it’s a solid investment. I’ve seen cheaper cases fail after a few uses, but this one feels like it will last years.

The Not-So-Good: Areas for Improvement

• No floaty backdoor included: A missed opportunity for added safety.
• Touchscreen sensitivity: Slightly less responsive underwater.
• Sand vulnerability: Requires careful cleaning after beach use.
• Limited to Yi 4K/4K+: Not compatible with older models.

None of these are dealbreakers, but they’re worth noting. The floaty backdoor issue is the biggest gripe—it’s a safety feature that should be standard.

Final Verdict: Who Should Buy This?

If you own a Yi 4K or 4K+ and plan to shoot underwater, this kit is a must-have. It’s reliable, well-designed, and priced competitively. I wouldn’t trust my camera to anything else for snorkeling, diving, or water sports.

For casual users who only need splash protection (like hiking in the rain), a cheaper case might suffice. But if you’re serious about underwater content, the Yi Waterproof Case Kit delivers peace of mind. After my Philippines disaster, I’ve never had a leak or fog issue—and that’s priceless.

One last tip: always test the case in shallow water before deep dives. Submerge it for 5 minutes, then check for moisture. It’s a simple step that could save your camera.
