From March 6 to 8, 2026, the DRT Show Shanghai turned the Shanghai World Expo Exhibition & Convention Center into the largest underwater trade floor in Asia. Over three days, divers, content creators, and industry partners packed the aisles to see what is next in underwater imaging — and the DIVEVOLK booth became one of the show's most crowded stops, driven by two products that represent where smartphone underwater photography is heading: the SeaLink WiFi signal transmitter and the SeaTouch 4 Max Platinum Almighty Kit.
A booth backed by international awards
Walk up to the DIVEVOLK stand and the first thing visitors noticed was not a product — it was the award wall. Above the hands-on display sat two internationally recognized honors: the German Dive Award (Tauchen innovation prize, both 2024 and 2026 cycles) and a Scuba Diving "Best Buy" seal. For a brand built around a single, ambitious idea — making a smartphone fully operable underwater — external validation from two of the industry's most respected testing programs set the tone for every conversation that followed.
The booth itself was designed around two product stories. On one end, the SeaLink live-streaming rig ran a continuous loop of underwater footage broadcast in real time to the display screens above. On the other end, a full SeaTouch 4 Max Platinum Almighty Kit sat under acrylic — dual video lights, wide-angle lens, macro lens, and color-correction filters all mounted on the signature platinum aluminum housing. Between them, tables stacked with SeaTouch 4 Max PLUS retail boxes made it clear: DIVEVOLK came to Shanghai with a full product ecosystem, not a single hero SKU.
SeaLink: bringing live streaming up to 30 meters below the surface
The headline product was SeaLink, a WiFi signal transmitter that does something the diving world has been asking for since Instagram Live launched: broadcast a real-time stream from depth without surfacing first. Visitors watched an iPhone, sealed inside a SeaTouch housing, streaming a shipwreck dive sequence with live comments scrolling up the screen. The demo rig was plumbed with SL50-class video lights and DIVEVOLK's external shutter controller, mirroring what a working creator would actually take into the water.
One spec deserves to be called out up front: SeaLink's live-streaming depth is capped at 30 meters / 100 feet, set by the length of the surface-buoy tether cable. The SeaTouch housing the phone sits inside is rated to 60 m / 200 ft, but real-time broadcast itself stops at 30 m — beyond that, the phone keeps shooting and recording, but the live signal no longer reaches the surface buoy. Plan dive profiles around the 30 m streaming ceiling, not the housing's pressure rating.
The rest of the spec sheet does the heavy lifting: broad phone compatibility spanning iPhone 12 through iPhone 17 plus the major Android flagships, and third-party app access for Filmic Pro, Slow Shutter, and manual-mode RAW shooting. At surface, the same unit supports phone calls, video calls, GPS readout, and compass navigation — the underwater equivalent of not having to choose between being a diver and being reachable.
What landed with visitors, though, was not the spec sheet. It was the realization that underwater creators no longer need a separate dive camera, a topside operator, and a post-dive editing session to share a reef story. SeaLink collapses that workflow into a single smartphone-based rig — which is why the DIVEVOLK team framed the product with a single tagline across the booth wall: "开启全民水下直播时代" — ushering in an era of underwater live streaming for everyone.
Hands-on demos ran all three days
Booth traffic was steady from the 9 a.m. open, but the queue for hands-on time with the housings stayed consistently long. Visitors were handed a fully rigged SeaTouch setup — phone, housing, dual lights, shutter trigger — and walked through the touchscreen response, the quick-release lens swap, and the shutter half-press behavior at depth equivalents.
The most telling moment in every demo came when a first-time user tapped the screen and watched the focus point shift on-screen exactly the way it would in open air. DIVEVOLK's patented underwater touchscreen has been in production across four generations now, and the "wait, it actually works" reaction never gets old.
For creators already shooting underwater on dedicated cameras, the value proposition shifted as the demo progressed. Watching native iPhone 4K ProRes, computational photography, and in-app color grading work through a fully sealed housing reframes what a smartphone underwater can produce — especially at a price point a full-frame housing rig cannot touch.
SeaTouch 4 Max Platinum Almighty Kit: the full-stack creator rig
The second product centerpiece was the SeaTouch 4 Max Platinum Almighty Kit, displayed fully assembled with every accessory a working underwater creator typically adds over a year of incremental purchases.
The Platinum version swaps the standard polycarbonate shell for a machined aluminum body — visibly the most premium housing DIVEVOLK has ever shipped, and the one most directly aimed at professional photographers and videographers. Core specs:
- 60 m / 200 ft full waterproof depth rating
- 30 m / 100 ft confirmed touchscreen operational depth
- Phone compatibility up to 180 × 82.5 × 11.2 mm, accommodating iPhone Pro Max models through the current generation and most large-format Android flagships
- 100,000-operation touchscreen lifespan rating
- Dual 1/4-inch threaded mounting bases for accessory flexibility
- Multi-layer gasket sealing design
The Almighty Kit bundles the Platinum housing with two SL50 video lights (5,600 lumens each), a 0.6x wide-angle lens and +18 diopter macro lens, red and magenta 67 mm color-correction filters, a dual-handle tray with 447 g float arms, the DIVEVOLK external shutter, and a protective travel case. For creators building a rig from scratch, the kit removes the guesswork — every piece is engineered to mount, seal, and balance against the housing without third-party adapters.
Pair the Platinum kit with any current DIVEVOLK video light or browse the complete dive housing lineup to see how the ecosystem scales across use cases from snorkeling vloggers to commissioned reef-science documentation.
Live presentations and partner voices
Throughout the show, DIVEVOLK ran scheduled demo sessions on the hour, walking visitors through the SeaLink streaming workflow, the SeaTouch touchscreen architecture, and the kit-building logic behind the Almighty bundle. Community partner DIVE FOR LOVE (潜爱) shared the stage — a reminder that underwater imaging is only as impactful as the ocean-conservation stories it amplifies.
The presenter format worked. Booth visitors stayed for 15- to 20-minute blocks, asked follow-up questions about streaming bandwidth, deep-water performance, and conservation use cases — the kind of engaged, technical audience trade shows are supposed to attract but rarely actually do.
What DRT Shanghai 2026 signaled for underwater content creation
Three days of conversations made one trend obvious: underwater content creation is no longer a niche intersection of dive skill and specialist hardware. With SeaLink, a smartphone becomes a live broadcast studio at depth. With the SeaTouch 4 Max Platinum Almighty Kit, the same smartphone competes with housings costing several times more, in a form factor any traveling diver can actually pack. The two products do not compete — they stack, and the audience at DRT Shanghai clearly understood that.
For divers who could not make it to Shanghai, the same products are in full distribution. Start with the SeaLink live-streaming transmitter if broadcast and real-time sharing is the priority, or jump directly to the SeaTouch 4 Max Platinum Almighty Kit for a complete pro-level underwater smartphone rig ready for the first dive out of the box. Questions, compatibility checks, or deployment guidance — the same team that ran the Shanghai booth is available by email and regional distributor.
Shanghai was a milestone. The next step is getting these tools into the hands of every diver who has a story below the surface worth sharing.
