Expansion Clamp for Sea Touch 4 Underwater Housing Including Red Filter/Purple Filter Clamp + Conversion Ring

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.

As described Would like the ability to mount both filters rather than have to swap them out Used it on a weeks sea dive - will see how it holds up to seawater

I recently purchased the lens attachment for the SeaTouch 4 Max, expecting it to elevate the functionality of the base unit. Unfortunately, I was left feeling that this is a feature that should have been included in the original SeaTouch 4 Max—and after using it, I can see why it wasn't. Straight out of the box, the attachment's metal components were covered with an odd, multicoloured, oily sheen giving it an eroded look. This immediately raised concerns about the quality and durability of the materials used. Worse still, two of the mounting screws showed signs of rust or corrosion before I even touched them, which is unacceptable for a product designed to be used underwater. When I attempted to attach the unit, the screws wouldn’t thread in properly, making it impossible to securely mount the lens. Even if I had been able to, the fit was poor. It felt like the attachment was too small for the base unit, causing it to bend in areas where it clearly shouldn’t. I wouldn’t trust putting any additional attachments onto this, as it feels like the whole thing could break under pressure. Overall, this attachment falls short of expectations. The fit, finish, and durability issues make it hard to recommend, and it's disappointing that such a key feature was left out of the base model, only to be executed poorly in this add-on. Not worth the investment.

The clamp would just not screw on. I had to order another one as I spent hours trying to screw it on and it just wouldn't happen. There was not enough place at the bottom for the screw to fit in.

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 👍

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.

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