ED stands for extra-low dispersion — the glass elements are engineered to reduce chromatic aberration, the coloured fringing you get around high-contrast edges at dawn or dusk. Standard HD glass improves transmission and contrast but doesn't fully solve fringing. On something like the Forester 8x42 ED or the Alta 12x50 ED, you'll notice it most when scanning a treeline in flat autumn light. If you're using binoculars mainly in good midday light, HD is fine. Low-light field work — stalking, coastal watching — ED earns its price.

The Coastline 10x50 HD is built for exactly that. Higher magnification, larger objective, and the HD coating stack handles the haze and glare you get off open water. The 50mm objective pulls in enough light for early morning watches. If you're on a tripod-mounted setup and need to hold at range for long periods, the Stonepass 80mm Angled Spotting Scope is the better tool — but for handheld coastal work, the Coastline 10x50 is what we'd reach for.

Yes, we ship to all three. Norway and Switzerland sit outside the EU, so orders may attract import duty on arrival — that's determined by your local customs authority, not us, and we can't predict the exact figure. UK orders are handled the same way since Brexit. We declare goods accurately on all customs documentation. Turnaround from order to dispatch is typically two working days, and we send tracking information as soon as the parcel is on its way.

Manufacturing defects in materials and assembly — for the life of the product. That means if a prism shifts, a coated element delaminates, or a focus mechanism fails under normal use, we repair or replace it. What it doesn't cover: physical impact damage, water ingress from a missing O-ring you left out, or wear from field use over many seasons. Send it back to us with a short description of the fault. We'll assess it and come back to you within five working days.

Yes. Thirty days from receipt. The optic needs to come back in the condition you received it — original case, caps, any included accessories. We don't charge a restocking fee. If you're unsure between the Ridgeline 7x35 Porro and the Forester 8x42 ED, honestly, try one and see. The Porro gives you a wider, more three-dimensional image. The ED corrects colour fringing. They're different tools. We'd rather you had the right one.

Start dry. A soft brush or lens blower removes dust and grit before you touch the glass — that's where most coating scratches come from. For smears, a microfibre cloth and a small amount of lens-specific cleaning fluid, worked in light circular strokes from the centre out. Don't use shirt fabric, tissue, or anything that's been in your pocket with sand in it. The coatings on the ED and HD ranges are durable, but they're not indestructible.

Objective size drives low-light performance and maximum magnification ceiling. The 65mm straight scope is lighter and packs smaller — it's the one to carry if you're covering ground on foot. The 80mm angled scope is the choice when you're set up on a fixed position: a high seat, a headland, a long coastal transect. The angled eyepiece is easier to share with a companion and more comfortable over extended sessions. Both accept the same eyepiece range.

We do, on a case-by-case basis. Bring in or describe what you have — brand, model, condition — and we'll give you an honest assessment. Good glass holds its value. If it's something we can service and resell, we'll offer store credit against a new purchase. We won't take in anything with significant impact damage or missing elements, but a well-kept 10x50 from a respected maker is usually worth having a conversation about.
