Expansion clamp for seatouch 4 max housing Including Red Filter/Purple Filter +Clamp+Conversion Ring

I would consider this accessory a requirement, and the functionality is now built in to the larger housing. This clamp is great. Can attach red filters and wet lenses easily and can move them out of the way easily as well. On a few dives after moving the lens out of the way a few times I like to check and ensure the screw is still tight, but I can't imagine using the housing without this accessory.

Like others have stated the screw mechanism can come loose resulting in lost components. Mine didn’t but I can see how it could happen and I had to worry about it in the back of my mind. Otherwise excellent quality.

I bought the sea max 4 and it works perfectly for dives and snorkeling! You can see real time what the quality of your images will look like with no surprises later if your camera was not set up correctly! Not only is the set up amazing but the customer service I have received before, during and after my purchase has been incredible! Thank you will definitely be recommending to others

This absolutely helps with color correction. I just wanted something simple to use with my phone. As others have said, it can come loose from the divevolk during use but personally I have had no issue with it coming loose while diving. I tighten it before a dive and then I check it once or twice during the dive. I rarely have to tighten it but I have on occasion. If I never checked it, I could see it being an issue on occasion. With this in particular, I have had a problem with “low light” alert on iPhone 16pro max at about 100-110ft. The photos/videos still come out fairly clearly, just not as crystal clear as at 50-75ft.

I had the original clamp from Divevolk from my Seatouch 3 and i found it to be extremely useful. The clamp system allows for attaching the unit to lights, trays and lights and is a total must have. It also allows for different filters to be used on it. The red filter is very useful to have and the clamp easily allows for the filter to be pushed out of the way during flash/light situations. The original design was a split design that was held together with a tightening screw that also held the filter holder. There was an issue with the old design if the filter screw came loose it would also loosen the clamp. Now DV has introduced this one piece design that eliminates that issue. As it is one piece the clamp stays in place. I am now using this new clamp system on my Seatouch 4 housing. It is so much improved and so useful to enhance my camera system. Totally recommended.

Great addition to DIVEVOLK iPhone case.

I have the Seatouch 3 and the filter fits great and secured. I updated my phone and was forced to buy the Seatouch4 and the filter for it. The mechanism to attach the filter to the housing is not well designed and the first time I used it, it came off and lost it at sea. Why did Divevolk changed the mechanism of the filter is beyond me, but I am no longer a fan.

Really good product, made with good materials. The installation is very straightforward

Perfetto, semplice da utilizzare anche con dei guanti nelle operazioni di fotografia subacquea, oggetto di fondamentale utilizzo per il bilanciamento del bianco per profondità maggiori a tre/cinque metri.

waste of money

Très beau matériel 👍

Cambia por completo la experiencia del buceo, lo uso con el iPhone 16 pro Max. Vale la pena

Arrived quickly with no issues however the red filter lens was extremely loose and rattling around in the ring. The Magenta one was solid and did not rattle however had to return for refund so cannot comment on the product in use. I still need the expansion arm so will probably order another but annoyed that I need to now be out of pocket buying another and having to go to a drop off for a faulty item and then wait on a refund.
