    StandoutExceptional marine biodiversity

    Alright, the Erme Ingot site. We love this one for its sheer simplicity and genuine historical weight. You’re not getting a grand, intact wreck here. Instead, it’s a scatter, a field of ancient tin ingots lying on the seabed at a gentle 10 metres. The water often has that Cornish emerald tint, soft light filtering down, illuminating these metallic lumps that have been down there for centuries. It’s a quiet dive, best suited to those who appreciate history and the slow creep of the sea claiming human artefacts. We’d suggest going at slack tide, really taking your time to trace the pattern of the ingots. Some are half-buried, others completely encrusted with dead man’s fingers and small anemones. Look closely among them, and you’ll find gobies darting between the crevices, tiny crabs scuttling. It feels like you’re diving through a forgotten cargo hold, an almost meditative experience. This isn’t about big pelagics or vibrant corals; it’s about touching a piece of Britain’s maritime past, letting your imagination run a little wild about the vessel that carried them.
