Buying guide
Match the accessory to the camera you actually dive
This range splits cleanly into two systems. If you dive a GoPro you are buying housings, poles, floats, batteries, cases and anti-fog inserts. These are entry-level parts, they are forgiving, and they largely work together without much thought. If you dive a full housing rig you are buying into the Marelux system, where ports, viewfinders and triggers must match your specific housing and lens. Those are premium parts and the wrong one is an expensive paperweight. Work out which system you are on first, then check compatibility before you order. Tell us your camera body, your housing and the lens you want to shoot, and we will confirm what fits before anything leaves the shelf.

Frequently asked questions
Which camera accessory brands does Oyster Diving stock?
Two, and they serve different divers. GoPro covers the action camera side: dive housings, poles, floats, batteries, cases and anti-fog inserts. Marelux covers the full housing side: ports, viewfinders and flash triggers for a proper interchangeable-lens rig. If you need a part for a system we do not list here, ask us and we will tell you straight whether we can source it.
What do I actually need to take a GoPro diving?
Start with the housing. The GoPro Dive Housing for the Hero11 Black Mini and the GoPro Protective Housing are the two we stock, so match one to your camera. After that it is the boring kit that saves dives: anti-fog inserts to keep the port clear, a Floaty so a dropped camera comes back up rather than going down, and a spare Enduro battery. A Shorty mini extension pole tripod or the extension pole with waterproof shutter remote gives you something to hold that is not your own wrist, which steadies the footage more than people expect.
What is a port, and do I need a macro one?
A port is the front section of an underwater housing, the window your lens looks through. Different lenses need different ports, and a macro port such as the Marelux Macro port 32 is built for close-focus work on small subjects. If you want to fill the frame with a nudibranch or a blenny, that is the port you are reaching for. Ports are matched to a specific housing and lens combination, so check the pairing before you order. Send us your housing and lens and we will confirm the fit.
What does a 45 degree viewfinder change?
How you hold the camera. A straight finder means getting your eye directly behind the housing, which is awkward when the subject is on the bottom and you are trying not to flatten yourself into the sand. The Marelux 45 Degree Viewfinder angles the view upward so you can shoot low and still see what you are framing. Macro shooters tend to fit one and then never take it off.
Why does my housing fog up, and how do I stop it?
A sealed housing keeps water out, and it keeps whatever air you sealed inside it in. Load the camera somewhere warm and humid and that trapped moisture condenses on the inside of the port the moment the housing hits cold water. Anti-fog inserts sit inside the housing and pull that moisture out of the air. Fit fresh ones, close the housing in the driest and coolest place you can find rather than on a sunny boat deck, and keep it out of direct sun until you get in.
