Diving the Signal always feels like stepping into a cold, dark history book. She’s not one of those meticulously preserved wrecks, but a proper Scottish West Coast experience, rough and ready. We love the way she sits, broken but defiant, her plates slowly disintegrating into the seabed. You'll find yourself navigating through chunks of twisted metal and exposed ribs, each revealing a little more of her story. It’s a dive for those who appreciate the raw beauty of decay, where the structure itself becomes an artificial reef. Visibility here can be a bit of a gamble, often swinging from decent to “where’s my buddy?” within minutes, especially after a storm. But that’s part of the charm; it adds to the adventure. We’ve had some cracking dives exploring her, finding crabs scuttling in the shadows and lobsters tucked into every crevice. Look out for the nudibranchs, often clinging to the rust-coloured metal, their colours popping against the gloom. This isn't a beginner's wreck; the conditions, particularly the surge and chill, mean you need to be comfortable in colder, darker water. But for experienced wreck divers, it's a solid day out, a chance to connect with a piece of maritime past.
