Miguel Ollero (@OlleroR3scates) has spent 30 years diving and 35 years as a professional firefighter in Spain. He's a dive instructor, a trainer of multidisciplinary rescue teams, and a specialist in aquatic and underwater rescue. He sent us his experience with the DIVEVOLK SeaTouch 4 Max in his own words. What follows is his account, translated from Spanish and lightly edited for length.
I Almost Bought an Action Camera
I had the money set aside for a dedicated action camera. Then I started reading about underwater smartphone housings and stopped.
I want to be clear about why I stopped. It wasn't because I was convinced. It was because the whole idea made me uncomfortable. Look at what a housing actually asks of you: take an expensive phone, the one carrying your contacts, your photos, your work and your bank, and deliberately put it in the water. That takes some talking into. I came to the DIVEVOLK housing as a skeptic.
Why I Bought It Anyway
What decided it was an argument about equipment that I apply to everything I buy for work.
I didn't want to spend a fortune on a good action camera plus its own underwater housing and then have the whole kit sit in a drawer between dives. That happens more than people admit. You buy the camera for a trip, use it twice, and it ends up in a cupboard with a flat battery while the phone in your pocket does the actual work.
My rule is simple. If you already own a tool that does the job, use it and make it pay for itself. Don't duplicate. Make it serve the activities, the work and the hobbies you actually do.
So I read the SeaTouch 4 Max specifications properly, and I bought one.
The First Dive: 32 Meters
The hard part was the first descent. After that, nothing.
Once I got past the reluctance to actually put my phone in the water, the housing beat my expectations by a wide margin. I've since taken photos and video down to 32 meters with it.
What made the difference was that I didn't have to change the way I shoot. The touchscreen works, so I frame, switch between photo and video, change cameras and check what I've already recorded, all with the phone sealed inside. No guessing. No surfacing to find out the last ten minutes were pointed at my fins.
Canyons, Kayaks and Rescue Drills
Since then the housing hasn't stayed in the dive bag. Canyoning descents, kayak runs, paddle surf, heavy swell and strong current. I also use it while teaching water rescue courses for emergency services personnel, and professionally that's the use I care about most.
In training, a camera isn't a souvenir. It's a teaching tool. When a team crosses a river in current, or recovers a casualty onto a raft, ask them afterwards what happened and you'll get five different accounts of the same fifteen seconds. Everyone remembers their own hands and nothing else. Footage ends the discussion.
What I hadn't anticipated when I bought it is how much the phone itself matters there. The image quality is whatever your phone can do, and phones are capable of a great deal now. But the real gain is that the pictures are already where you need them. No card to pull, no transfer, no laptop, no cable, no waiting until you get home. I can show a trainee the exact second their body position let the current take over while we're still standing on the bank, wet, with the drill fresh in everyone's head. The debrief happens that same afternoon instead of the following week.
The rest is peace of mind. The phone stays properly protected, and DIVEVOLK sells enough kit and accessories that you can adapt the setup to whatever you're doing: a dive light when the water goes dark, a lens or filter when I want a wider frame. The core of it doesn't change.
One Thing I'd Change
I should be honest about wear, because I use this housing in places it was never specifically designed for.
Diving is a controlled environment. Canyoning, rescue drills and boat work are not. Between rock, gravel, boat tubes and the occasional unplanned drop, mine has picked up scratches over the months. It hasn't affected the seal in any way. It's purely cosmetic. The housing just looks older than it is.
What I miss is an accessory: a full silicone or rubber skin, like the ones people put on their phones to survive drops. Easy on, easy off, not too thick, but enough to take the abrasion from boats and rocks and to absorb a knock. I can't see it costing much to make or to buy, and I think almost every owner would pick one up. Offer it in a few solid colors, some mixed or camouflage ones, and I suspect it would sell itself.
That's my suggestion. Until it exists, I do what I tell my own trainees to do: rinse it thoroughly after every session and store it properly. DIVEVOLK's guide to cleaning and maintaining a housing after a dive covers the routine, and the housing care and accessories guide is worth reading before you take one anywhere rough.
What I'd Tell Another Diver
If you're hesitating for the reason I did, because putting an expensive phone in the sea feels reckless, I understand. It's a fair thing to worry about. Mine lasted one dive.
Since then the SeaTouch housing has been to 32 meters, through gorges, down rivers, and into training scenarios with firefighters and emergency crews. It replaced a purchase I was about to make, and it gets used far more than that purchase ever would have.
Buy the tool you'll actually carry.
