DiveVolk SeaTouch 4 Max Smartphone Housing Review

A touchscreen compatible smartphone case for scuba diving!
By Nirupam Nigam

The DiveVolk SeaTouch 4 Max has taken the dive & snorkel world by storm. As the top touchscreen compatible smartphone housing, its popularity has begun to eclipse bluetooth controlled smartphone housings like the SeaLife SportDiver and the Kraken KRH08 Universal Smartphone Housing. The SeaTouch 4 Max is surpisingly affordable, coming in at $199. It is compatible with most smartphones on the market. Natively, it works with most modern iPhone models from the iPhone 6p to the iPhone 14 Pro Max. If it does not work with your phone, or you have an Android, Huawei, etc, you can order a custom 3D printed tray from Bluewater Photo for $10 or receive a free STL file from Bluewater

The DiveVolk SeaTouch 4 Max in the Field

We took the DiveVolk SeaTouch 4 Max diving at Catalina Island, California with a wide range of accessories to see if it truly lives up to the hype. The housing does indeed accomplish the amazing feat of allowing you to take photos and videos on your phone's native applications using the touch screen. However, there are important distinctions that should be made between the SeaTouch 4 Max and other smartphone housings that use Bluetooth control. So read our full underwater review of the DiveVolk SeaTouch 4 Max to see if it's the housing for you!

DiveVolk SeaTouch 4 Max Design and Durability

As you can see by the specifications, the SeaTouch 4 Max is a very simple underwater smartphone housing compared to others on the market. It's is built with a firm polycarbonate and aluminum body and designed to be taken to depths up to 60 meters (200 ft). In order to install your phone, you place your phone in a plastic tray and insert it into the housing. Then you screw down the housing door with a built in compression o-ring.

Reading this article, you may be wondering if the housing is safe enough for your precious phone. At first, we were surprised that there was no vacuum system like bluetooth smartphone housings such as the SeaLife SportDiver and Kraken KRH08. It was a little unnerving watching the housing go underwater without knowing if it was watertight. But our fears quickly melted away as the housing withstood multiple dives. We dived in rough waters in both California and the Galapagos - full of surf and current.

Touchscreen Controls

You may be wondering how the housing allows you control your phone. The back of the housing has a clear plastic film filled with a glycerin-like gel. When you push firmly on the gell you are able to use your phone's touchscreen almost like you would above water. We found that you had to be a little more forceful than when the phone is not in the housing - but it did a pretty good job. I didn't even have to worry about unlocking my phone with the security code - I could do it just fine underwater. One important thing to note, however, is the fact that you cannot use the touchscreen controls with gloves. You need to use bare skin to use the touchscreen. If you are diving in cold water with gloves, you will need a DiveVolk touchscreen finger cot. 

We did notice one idiosyncracy with the DiveVolk housing - while flying the housing seemed to develop bubbles in the gell. However, that's nothing to worry about as the bubbles go away when you use it underwater.

DiveVolk SeaTouch 4 Max Accessories

DiveVolk Lens & Filter Adapter

This lens and filter adapter is a must have accessory for the SeaTouch 4 Max. It allows you to get creative with your photos and videos by adding color correction filters and wide angle & macro lenses to the front of your phone. The adapter can also be used to help you attach an underwater tray and lighting system to your system.

DiveVolk Macro 8+ Wet Lens Close Up

The DiveVolk macro +8 wet lens is a great option for underwater photo and video shooters that want to take up-close of small subjects - about the size of a golf ball.  

DiveVolk Underwater Wide Angle 0.6x Conversion Lens

DiveVolk Underwater Wide Angle 0.6x Conversion Lens

The DiveVolk wide angle conversion lens allows you to get closer to your subject with a wider field of view. This is great for shooting large subjects as well as for getting close for better detail and color in your image. This lens is designed for your phone's normal 1x camera, not the wide angle lens.

DiveVolk Red and Magenta Filters

DiveVolk red and magenta filters are great for correcting colors underwater. In blue water, we recommend the DiveVolk red filter to bring back red colors lost at depths of 5 meters to 25 meters. The DiveVolk magenta filter corrects colors in green water at depths of 5 to 15 meters. 

These beautiful colors were captured using just the red filter!

DiveVolk monitor

DiveVolk SeaLink Contact Type Underwater Wifi Signal Transmitter

Perhaps the coolest application of the DiveVolk SeaTouch Max 4 housing is the fact that it will allow you to use your smartphone as an underwater monitor for your camera. The transmitter transmits WiFi signal from your smartphone to your camera. It allows the user to operate the camera using the smartphone or use the smartphone as a monitor!
