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

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.

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 like the product overall, but while diving, the filter kept sliding down in it's track. No matter how tight I tightened it, it would loosen up when I move it back and forth to use or not use it. So that was a bit of a pain. that being said, i would still buy this product, this is just something to be aware of

The expansion clamp with the red filter is an excellent addition to my Divevolk Underwater Case for iPhone 15 Max Pro. With this attachment it adds back the res color to my photos so they don’t look blue as a result.

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

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.

I just traveled to the BVI and it was perfect for small and compact underwater photography options! This coupled with a Divevolk underwater camera/phone case, divelight attachment and wide angle lense attachments was exactly what I needed for a one week sailing excursion!
