If you already shoot with a SeaTouch 4 Max Plus, the useful question is whether the SeaTouch 6 Pro changes anything about the parts of a dive that currently annoy you. DIVEVOLK has published an item-by-item comparison between the two generations alongside the launch, and the honest reading is that some of those items will change your dives noticeably and some will not matter at all depending on how and where you shoot.
Here is the official comparison, followed by what each row means once you are in the water, and a section on when staying with the housing you own is the right call.

The Upgrades You Will Feel on Every Dive
The Swipe-Up Gesture Comes Back
This is the one that changes muscle memory. On a SeaTouch 4 Max with a large phone, you could not swipe up from the bottom edge to return to the home screen, so the workaround was AssistiveTouch: an on-screen button standing in for a gesture the membrane could not reach. It worked, and it also meant an extra tap every time you left the camera app to check something. The SeaTouch 6 Pro reworks the touch window to cover more of the screen, restores the native swipe-up, and makes edge touches register more easily. DIVEVOLK also says newer phones can keep their screen protector on inside the housing.
If edge gestures have been your daily irritation, this is the row that justifies the upgrade on its own. Our SeaTouch 4 Max touchscreen troubleshooting guide describes the behavior this generation is designed to remove.
A Red Filter You Do Not Have to Assemble
Water strips red light out of the spectrum in the first few meters, which is why shallow shots come back blue, as NOAA's National Ocean Service explains. The SeaTouch 4 Max Plus had no filter in the box, so shallow color correction meant buying a filter and usually a clamp to hold it. The SeaTouch 6 Pro ships with a snorkeling red filter tuned for 0 to 10 meters that clips directly onto the lens window with no bracket at all.
For a diver who mostly works below 10 meters this row is close to irrelevant, since deeper color still comes from a filter tuned for range or from a video light. For anyone who snorkels, freedives, shoots in pools or takes the housing to the beach, it removes a purchase and a setup step.
Fog Control
The SeaTouch 6 Pro has a built-in desiccant pad slot and pads in the standard package. The previous generation was not compatible with a pad, and its lens could fog when a warm housing hit cold water. If you dive somewhere with a real thermocline, or you load your gear on a hot deck and descend into 15 degree water, this quietly saves dives. If you dive tropical water year-round and have never seen your glass fog, it will not.
The Shutter Fits Either Hand
The Underwater External Shutter mounts in two positions on the SeaTouch 6 Pro instead of one, so it lands under the thumb whether you hold the rig left- or right-handed, and the inverted position puts the lens closer to the seabed for low-angle macro. That matters most to macro shooters and to anyone whose grip was fighting the single mounting point. Both generations are button-free housings, so a phone sealed inside cannot have its volume or power buttons pressed, and this Bluetooth trigger is the only tactile shutter either housing has. Our external shutter write-up covers how it pairs.
The Upgrades That Depend on What You Shoot
18 mm of Clearance
The internal envelope grows from 15 mm to 18 mm and takes phones up to 180.0 × 82.5 × 11.2 mm with a camera bump as tall as 17 mm. That opens the housing to thick-module Android flagships such as the vivo X300 Ultra and Xiaomi 17 Ultra, which did not fit the previous 15 mm ceiling, alongside every iPhone through the iPhone 17 Pro Max and the Samsung Galaxy S26 Ultra.
Read this row as insurance rather than as a feature. If your current phone fits your current housing, nothing changes today. If your next phone has a camera module the size of a cookie, which is where the industry has been heading, the extra 3 mm is what keeps the housing usable through that upgrade. Check your intended model against the current compatibility list through technical support before committing.
The Dome Port
The new housing has an integrated dome port mounting slot, so the second-generation Dome Lens attaches with no extra adapter, and its larger window covers the main and ultra-wide cameras at once. The previous dome covered one lens, which meant repositioning it if you wanted to switch phone cameras mid-dive. For split-shot work, one click of the AquaLock structure holds a steady waterline between dome and housing glass. Anyone who shoots half-and-half regularly will notice this immediately; anyone who has never owned a dome will not. The technique side is in our dome port guide, the optics are in lenses and filters, and the PADI Blog covers the composition habits that decide whether a dome earns its space in your bag.
Membrane Lifespan
The swipe endurance standard rises from 100,000 cycles to 150,000, with a new material and a new multi-layer assembly process behind it. This is a bench standard from DIVEVOLK's testing rather than a warranty term, and it describes the film's designed durability. What it does not do is override care: a membrane that gets sunscreen, sand and dried salt left on it will not reach any number. Divers Alert Network makes the general point about pressure-bearing gear, and our O-ring maintenance guide covers the specifics.
Weight and Trim
On land the SeaTouch 6 Pro is 40 g heavier at 475 g. In the water with an iPhone 16 Pro Max it is 5 g lighter at about 150 g, which is marginally closer to neutral. Neither number changes your weighting on its own. What changes trim is what you hang off the rig, so if you are moving lights and lenses across from an older setup, sort your buoyancy out on the first dive rather than the third.
What Did Not Change
The depth rating is 60 meters on both, roughly twice where recreational diving takes place, and pressure still climbs about one atmosphere every 10 meters regardless of what the housing is rated for, as NOAA notes. Both housings run the phone's own camera and any third-party app through the membrane with bare fingers, with no companion app and no special mode to configure. Both pass GPS and cellular at the surface. Both let you review footage underwater. The core idea of the line is intact, which is the argument for the SeaTouch 4 Max Plus remaining a good housing rather than a superseded one.
When You Do Not Need to Upgrade
Several situations genuinely do not call for a new housing.
Your phone fits, your membrane is healthy, and you shoot mostly between 10 and 30 meters with a light. In that case the red filter, the desiccant slot and the 18 mm clearance all address problems you do not have, and the swipe-up fix may be worth less than the cost of replacing a working housing.
You have a SeaTouch 4 Max Platinum V2. That revision already brought a fifth-generation touchscreen reinforcement, so the membrane gap between it and the sixth generation is narrower than the table suggests. The Platinum V2 launch note and the product page cover what it includes.
You dive a handful of times a year. A 100,000-cycle membrane standard is not a constraint at that frequency, and money is better spent on a lens or a light that changes your images than on a housing that changes your workflow.
You are mid-way through a phone. If you plan to keep your current model for another year and it already fits, buy the housing when you buy the phone, not before.
The clearer upgrade cases are the opposite of those: you shoot shallow and want color without assembling anything, you fight fog, your large phone has been stuck behind AssistiveTouch, you shoot macro and want the shutter on the other side, or your next phone is thicker than 15 mm.
If You Do Move Up
Wet lenses and lights generally carry across, but the parts bolted to the body changed. DIVEVOLK rebuilt the Expansion Clamp for this generation, enlarged the travel case so the housing packs with clamp and dome attached, and moved the dome to an integrated slot. Confirm any specific old accessory with technical support before assuming it transfers. For the difference between a full-touchscreen housing and a button-controlled one, which is a separate question from generation-to-generation, see our comparison of touchscreen and button housings, and the older generations are laid out in the SeaTouch 4 comparison guide.
