What is the certified depth of the SeaTouch 4 versions?
All versions (Max Plus and Platinum) are certified to 196 ft (60 m). The difference is not about depth but about phone compatibility, CNC aluminum vs polycarbonate build, and access to the Almighty optical accessory mount.
Is the Platinum really better for macro?
It is more stable for additional macro lenses thanks to the integrated Almighty mount. However, the TG-7 remains superior for extreme macro at 1 cm without any additional accessory.
Is the Max Plus compatible with the iPhone 16 Pro Max?
Yes. The Max Plus was specifically designed to accommodate the iPhone 16 Pro and 16 Pro Max, whose camera bump protrudes more than previous generations. Always check the official Divevolk compatibility list before buying.
Can you switch phones and keep the same housing?
In principle yes, if the new phone is on the compatibility list and fits within the internal dimensions of the housing. The Max Plus is more flexible on this point than earlier generations.
Does the SeaLink work with both versions?
Yes, the SeaLink (real-time video transmission) is compatible with the entire SeaTouch 4 range. The Platinum has a slightly cleaner interface for attaching the optical cable.
Is the Platinum worth the price for a beginner?
No. The price difference (about 150 euros depending on the kit) brings nothing photographically decisive for the first 50 dives. Get the Max Plus, dive a lot, and reassess in a year if you want to move to additional lenses.

Can you change your phone and keep your enclosure?
In principle, yes, if the new phone fits the compatibility list and the internal dimensions of the enclosure. The Max Plus is more flexible on this point than the earlier generations. Always check the compatibility list before changing your phone.
How much does it cost to replace the seal?
Between 15 and 25 euros depending on the model, directly from Divevolk. Replace every 200-300 dives or as soon as visible signs of wear are apparent.
Is there a warranty?
Divevolk offers a one-year manufacturer's warranty. The after-sales service is known to be responsive - this is a point that I have personally verified during my incident with an empty enclosure (details in the article [iPhone + DiveVolk](/en/blog/iphone-divevolk-why-i-replaced-all-my-underwater-photo-and-video)).
Does the Platinum justify its price for a beginner?
No. The price difference (around 150 euros depending on the kits) does not bring any photographic advantage for the first 50 dives with an enclosure. Take the Max Plus, dive a lot, and re-evaluate in a year if you want to upgrade to additional lenses.
Divevolk SeaTouch 4 Max Plus vs Platinum: Scuba Dive Test & Buying Guide (2026)
The Divevolk SeaTouch 4 housing comes in two primary configurations: the Max Plus, which has become the versatile standard model, and the Platinum, which is the CNC aluminum flagship. Both models share the same certified depth of 196 ft (60 m) and full underwater touchscreen access via a patented conductive gel membrane. The difference lies in phone dimensions, chassis construction, optical accessory mounts, and pricing. Here is our field guide to choosing the right model for your diving.
Why a Certified Housing is Mandatory: Factory smartphone ratings (IP68) certify only 5 ft to 20 ft (1.5 m to 6 m) in still fresh water for 30 minutes. Real scuba diving introduces saltwater corrosion, wave turbulence, and depth pressure that would instantly destroy an unprotected phone. Both SeaTouch 4 models are pressure-tested to 196 ft (60 m). Divers seeking electronic button alternatives with vacuum leak pumps can also explore the SeaLife SportDiver Ultra (130 ft / 40 m) and Kraken Sports KRH08 V2 (262 ft / 80 m).

What Both Versions Have in Common
Before delving into the differences, let us highlight the core shared engineering: both versions of the SeaTouch 4 are certified to 196 ft (60 m), feature a full-touchscreen gel membrane display underwater, incorporate a gel pouch that compensates for hydrostatic pressure changes, and have physical button cutouts for zooming and shutter actuation.
Both use the same secure screw-locking latch (no clips that can accidentally pop open under current) and the same philosophy of zero internal electronics. Divevolk's mechanical approach means there are no internal batteries to charge, no Bluetooth pairing to fail, and nothing to corrode between the seal and your phone.
There is no added depth reliability on the Platinum: both are rock-solid down to 196 ft (60 m).
The SeaTouch 4 Max Plus: The Model Preferred by Most Divers
The Max Plus was released at the end of 2024, primarily to accommodate the iPhone 16 Pro and 16 Pro Max, whose rear camera exceeds previous generations. The interior space has been enlarged to accommodate these formats.
In practice, if you have an iPhone 15 Pro, 15 Pro Max, 16 Pro, or 16 Pro Max, or a Samsung Galaxy S24/S25 Ultra, the Max Plus is the right choice. It is also compatible with the Pixel 8 Pro and Pixel 9 Pro via adapters.
The price of the Max Plus ranges from €400 to €450 depending on the chosen kit. This is the option I recommend as an entry-level option for someone who wants a serious housing without paying for options that they will not use in the first few years.
The Max Plus provides access to the Divevolk additional lens system via a standard port, but the range of lenses that can be directly mounted on the housing is more limited than on the Platinum.
The SeaTouch 4 Max Platinum: For whom and why
The Platinum has won the German Dive Award twice (2024 and 2026) and was the star of the Divevolk stand at the DRT Show Shanghai in March 2026. This is not just a marketing ploy: the Platinum offers something that the Max Plus does not.
The first advantage is the Almighty Kit system. The Platinum features a mount that allows you to directly attach wide-angle and macro lenses to the housing, without the need for an additional adapter. On the Max Plus, additional lenses are installed via a standard threaded port. With the Platinum, the mount is integrated into the housing design and holds the lenses more stably, without the risk of them coming loose underwater.
Specifically for macro photography, the difference is measurable. A macro lens attached to a dedicated mount, without any mechanical play, gives more consistent results than a lens on a standard threaded port. If you regularly practice macro photography (nudibranchs, cleaner shrimp, small gobies), the Platinum gives you greater optical stability.
The second advantage is cosmetic but not insignificant for traveling divers: the Platinum housing is made of aluminum, not polycarbonate. It is more scratch-resistant, better thermally insulated (less overheating on the surface), and more neutral in buoyancy.
The price of the Platinum with the complete Almighty kit is around 550 to 600 euros.
The Compatibility Question: Check Before You Buy
Before choosing between the Max Plus and Platinum, the number one question is compatibility with your phone. Divevolk regularly updates its compatibility list on its website, but here are the key points as of May 2026:
iPhones Pro and Pro Max from the 13 Pro are compatible with both versions. The difference lies in the internal storage: if you have a 16 Pro Max, make sure the version you are targeting has sufficient space for the camera bump.
Samsung Galaxy S23 Ultra, S24 Ultra, and S25 Ultra are compatible, but some models require an adapter. The Max Plus is generally more flexible in this regard.
Google Pixel 8 Pro and 9 Pro work with both versions using an adapter. The Platinum has an advantage here because the Almighty kit holds the adapter more securely.
If you have a phone outside of these ranges (mid-range, older phone), you may experience compatibility issues with both versions. Check the Divevolk list before ordering, or browse our underwater smartphone housing comparator to review over 120 tested phone models.
My advice, based on your profile
Are you a beginner or an occasional diver (5-20 dives per year): Choose the Max Plus. The price difference between the two versions often represents one to two nights of accommodation on a liveaboard. Invest that money in more dives instead of an aluminum housing, where you won't see a difference in your photos at this stage.
Are you a regular diver and enjoy macro photography: The Platinum is worth the price difference. The Almighty Kit system will simplify your underwater life (no need to unscrew a lens between two sites) and the optical stability in macro is real.
Are you producing professional content or teaching: The Platinum with the SeaLink (the real-time video transmission system that Divevolk presented in early 2026) is the most consistent option. Seeing what DiveVolk showed with this combination in the smartphone category at UPY 2026 gives you an idea of the potential.
Do you already own a SeaTouch 4 Max from a previous generation: Keep it. The difference between the old Max and the Max Plus is mainly the compatibility with iPhone 16. If your current phone is compatible with your existing housing, you have no reason to change.
What the two don't do
One point that many people forget when comparing versions: neither the Max Plus nor the Platinum compensate for light. Your phone produces images based on its sensor and ambient light. The housing, regardless of the version, is a neutral container.
If your underwater photos look blue or murky, the housing is not the issue. The culprit is light physics: water absorbs warm wavelengths, requiring proper white balance, proximity to the subject, and an understanding of ambient sunlight angles. Mastering these natural light techniques is the core mission of the AquaExposure training program.
The housing, on the other hand, only does one thing: it keeps your phone safe underwater. Both versions do this very well.
The Maintenance Question
Both versions have the same maintenance requirements. Before each dive, check the main seal and the gel pouch. Rinse with fresh water after each dive. Store in the shade, never in a car trunk during the summer.
The seal requires replacement approximately every 200-300 dives, or as soon as it shows signs of deformation or initial crushing. Divevolk sells replacement seals separately.
A point that is not always mentioned in the descriptions: Never dive with an empty case. The waterproof gel is designed to work with the pressure created by the phone inside. Without the phone, the water pressure deforms the case differently, and you risk the design not being suitable for handling.
What I've found in my camera bag over the past few years
What I can say here is: the difference between the Max Plus and the Platinum won't change the quality of your images. It will change your workflow if you use additional lenses, and it will change the cosmetic durability of the housing if you dive frequently while traveling.
Neither is a bad decision. It's a matter of budget and preference, not photographic quality.
