I’ve been filming underwater with my iPhone 16 Pro inside the DIVEVOLK SeaTouch 4 Max Plus for years while freediving, so when DIVEVOLK released the new SeaTouch 6 Pro, I wanted to see what had actually changed for someone who already uses one of these housings all the time. In this article, I put all three next to each other for a DIVEVOLK SeaTouch 6 Pro vs 4 Max Plus vs Platinum comparison.

The quick answer: On land, the 6 Pro gives me an easier swipe-up gesture and a better one-handed grip than my 4 Max Plus. Its shallow-water filter and new dome are also simpler to attach, while the Platinum feels much heavier in my hands.

So, What Actually Changed?

Here is the quick comparison. The weights are from my own scale, with no phone or adapter inside; the product details come from DIVEVOLK’s 6 Pro comparison, 6 Pro product page and Platinum product page.

Unboxing the SeaTouch 6 Pro Water Sports Kit

What Came in My Box?

My shipment included the SeaTouch 6 Pro housing, an adapter for my iPhone 18 Pro, a second phone adapter, the new dome, the clip-on snorkelling red filter, a desiccant pad, an outdoor lanyard and stickers. The Water Sports Kit listing also includes a protective cover and travel case, but those two are being shipped to me separately, so they aren’t in my unboxing photos yet.

The Water Sports Kit does not include the new expansion clamp, so you need to order that separately if you want to use an external wet lens.

Does the iPhone 18 Pro Fit the SeaTouch 6 Pro?

Yes. With the SeaTouch 6 Pro adapter made for the iPhone 18 Pro, my phone fits properly, and I can use the touchscreen and swipe up while it is inside. I also checked the camera view with the phone in place, including from 0.5× to 8x zoom.

For this first test at home, I left my phone’s screen protector on and the phone still fitted. I’ll remove it before taking the housing into the ocean, though. DIVEVOLK’s FAQ recommends removing a protector because extra thickness can affect touch response or make a phone difficult to remove.

DIVEVOLK SeaTouch 6 Pro vs 4 Max Plus vs Platinum: Size, Weight and Grip

I put the three empty housings on the same scale, without phones or adapters: my 4 Max Plus weighed 451 g, the 6 Pro weighed 508 g, and the Platinum weighed 760 g. 

The interesting part for me is that the 6 Pro feels better in my hand than the lighter 4 Max Plus. It is bigger, but I can get a more comfortable one-handed grip on it, which I didn’t expect. I often have to hold the camera with one hand while I’m freediving, so that is very important to me than a small difference on a scale. I can also attach the lanyard on either side of the new housing, which gives me a little more choice in how I carry it.

The Platinum feels quite different because of its metal body. I like how solid it feels, but at 760 g on my scale it is noticeably heavier to carry around, and I don’t find it as comfortable for my usual freediving setup. 

Useful SeaTouch 6 Pro Updates for Underwater iPhone Photography 

Touchscreen and Swipe-Up

Full touchscreen control is the reason I’ve stayed with DIVEVOLK in the first place. When I film, I tap to focus, change between 0.5× and 1×, lower exposure when the surface is too bright, and sometimes move between apps without taking my phone out of the housing.

On my 4 Max Plus, AssistiveTouch has been part of that routine because the normal swipe up from the bottom of the screen can be awkward. On the 6 Pro, the gesture works directly with my iPhone 18 Pro, and the whole screen feels smoother to use during my test at home. I can imagine that saving me a few annoying taps when something appears suddenly underwater.

If you’re more interested in the camera settings and filming techniques I use once the phone is inside the housing, I explain those in 👉 How to Film Underwater With an iPhone.

The Included Red Filter and Anti-Fog Pad

I mostly freedive and film in relatively shallow water, so the new filter is one of the accessories I most want to test. My older red filter can make footage look too red when I’m close to the surface. The filter included with the 6 Pro looks less strongly red to me and, according to DIVEVOLK’s specifications, is intended for 0–10 m.

It clips onto the housing without an expansion clamp, which makes it much easier to bring along for a quick snorkel or freedive. Another nice update is, there is now a place for a desiccant pad behind the phone adapter. With my old setup, I normally put my phone in the housing before getting on the boat to avoid the forggy lens. The pad would give me a bit more flexibility.

The New DIVEVOLK Dome Lens

I’ve used the older dome for split shots, so I was curious about this one. The second-generation dome attaches directly to the 6 Pro’s integrated mount without an expansion clamp, and setting it up at home felt much more straightforward. The opening also covers more of the phone’s camera area. When I switched between the views I normally use during my test on land, I didn’t need to move the dome to line it up with a different camera.

DIVEVOLK calls the new design AquaLock and says it helps hold a cleaner waterline for half-above, half-below shots. That is exactly the sort of result I want to see for myself before judging the images. One important detail if you freedive: DIVEVOLK rates this dome to 3 m, even though the housing itself is rated to 60 m. I would use the dome for surface and very shallow split shots, then remove it for deeper dives.

Can I Use My Old DIVEVOLK Accessories With the SeaTouch 6 Pro?

This is the part I would check before ordering, especially if you already own several lenses and a full filming setup. The old 4 Max Plus expansion clamp does not fit the 6 Pro, so you need the new 6 Pro clamp to mount external wet lenses. The phone adapter and old dome also need replacing with versions made for the new housing.

The good news is that the lenses and other accessories attached to a clamp do not automatically become useless. DIVEVOLK says wet lenses, filters, lights and other rig accessories can generally carry over through the new clamp’s mounts, although it recommends checking the exact accessory before you buy. 

If, like me, you also want to use a separate wide-angle lens, you should include the cost of the new clamp when deciding whether to upgrade.

Where Does the Platinum Fit In?

The Platinum makes more sense once you hold all three together. Compared with my 4 Max Plus, it has a metal body, a built-in lens adapter and mounting points that suit a more built-out camera rig. DIVEVOLK also lists room for a taller phone camera bump than on the Plus, which is one reason someone with a larger phone might have chosen it.

For me, the weight is too much. If I were mainly building a setup with handles, lights and a tray for scuba diving, I could see why the Platinum’s construction and mounts would appeal to someone. For the way I usually freedive and film, I would rather carry the 6 Pro: I find it easier to grip, and it gives me the newer touchscreen, shallow-water filter and dome setup I want to try. 

Which Housing Would I Choose?

If you already have a 4 Max Plus, your phone fits, and you’re happy with the way you film, I wouldn’t replace it just because a newer number exists. I’ve made footage I love with mine.

For my next underwater filming trip, I plan to take the SeaTouch 6 Pro with my iPhone 18 Pro. It is the easiest of these three for me to hold with one hand, and I want to see whether the filter, desiccant pad and dome make the difference I’m hoping for. I’ll update this comparison after I’ve used it underwater in November.

FAQ: DIVEVOLK SeaTouch 6 Pro vs 4 Max Plus vs Platinum

Does the SeaTouch 6 Pro fit an iPhone 18 Pro?

Yes. My iPhone 18 Pro fits with the SeaTouch 6 Pro adapter made for that phone, and I’ve checked its fit and controls on land. 

Can I use my 4 Max Plus clamp and wide-angle lens on the 6 Pro?

You cannot reuse the old clamp; the 6 Pro needs its own expansion clamp. A 67 mm wet wide-angle lens may still be usable with the new clamp’s lens adapter, but check your exact lens model and its alignment before relying on it for a dive.

Do I need an expansion clamp for the 6 Pro’s red filter or dome?

No. The included snorkelling filter and the new dome attach directly to the 6 Pro. You need the new expansion clamp when you want to add an external wet lens or build out a setup with other mounted accessories.

Can I take the new dome as deep as the 60 m housing rating?

No. DIVEVOLK rates the housing to 60 m but the new dome to 3 m. The dome is for surface and shallow split shots, so check an accessory’s own depth limit rather than assuming it shares the housing’s rating.

Is the SeaTouch 6 Pro worth upgrading to from the 4 Max Plus?

If your current phone fits and the Plus already does everything you need, I don’t think the new housing is an automatic purchase. The upgrade makes more sense if you often struggle with the swipe-up gesture, want the shallow-water filter and new dome, need room for a larger phone, or prefer the new grip. My underwater opinion is still to come 🙂
