{"product_id":"sig-sauer-zulu4-10x42mm-hd-marine-binocular","title":"Sig Sauer ZULU4 10x42mm HD Binocular","description":"\u003cp class=\"nvn-hero\"\u003eThe Sig Sauer ZULU4 10x42mm is a premium HD binocular built for boaters who want a sharp, bright sight picture from sunrise to last light. High-definition glass, proprietary anti-reflective coatings and an IPX7 waterproof magnesium body make it a dependable companion for glassing the water.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen you're on the water, a good pair of binoculars earns its keep. The \u003cstrong\u003eSig Sauer ZULU4 10x42mm\u003c\/strong\u003e is built for boaters who care about what they see, whether that's reading a distant channel marker, picking a mooring ball out of a crowded anchorage, or watching birds work a bait ball on the horizon. It's a premium HD optic that pairs a bright, high-resolution sight picture with a body tough enough for real marine use.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the ZULU4 is Sig Sauer's high-definition glass, engineered for exceptional clarity and superior brightness. Paired with proprietary anti-reflective coatings, SpectraCoat, LensArmor and LensShield, the glass cuts glare and holds its edge in the harsh, reflective light you deal with out on open water. The result is a clean, color-accurate view that stays sharp from bright midday sun through the low, flat light of dusk. The 10x magnification and 42mm objective lenses strike a practical balance, close enough that you can hold them steady by hand, wide enough to gather plenty of light when the sky goes gray.\u003c\/p\u003e\n\u003cp\u003eThe build is where the ZULU4 really shows its intent. A reinforced magnesium housing keeps the optic light in your hands without giving up strength, and it's wrapped in rubber armor that shrugs off knocks against a console or a hard landing on a wet deck. It's IPX7 waterproof and fogproof rated, so a rogue wave, a driving rain squall or a quick dunk over the side won't put it out of commission. The internal purge keeps the lenses from fogging when you step from an air-conditioned cabin into humid morning air.\u003c\/p\u003e\n\u003cp\u003eHandling has been thought through for people who use their gear hard. The redesigned focus wheel has a precision contour overmold that gives you ultra-fine focal adjustment, so you can dial in a crisp image even with damp or gloved hands. The locking diopter ring lets you set your personal correction once and trust it to stay put, and the two-position twist-up eyecups work whether you wear sunglasses on deck or glass with the naked eye. Eye relief runs a comfortable 16mm, which keeps the full field of view available even for eyeglass wearers.\u003c\/p\u003e\n\u003cp\u003eOut at anchor or on a slow troll, you can mount the ZULU4 to a tripod using the standard 1\/4 inch by 20 threaded insert, which is a real advantage when you're scanning a shoreline for a long stretch and want to spare your arms. When it's time to stow, the newly molded EVA carrying case gives the binocular streamlined protection in a locker or a ditch bag, and the included neck strap keeps it within reach at the helm. The interpupillary distance adjusts from 56mm to 70mm, so the ZULU4 fits a range of faces and lets everyone aboard share the same pair without fuss.\u003c\/p\u003e\n\u003cp\u003eOn the water, that combination of light gathering and glare control matters more than raw magnification numbers on a box. Sun bouncing off chop can wash out a lesser optic and leave you squinting at a gray smear where a marker should be. The ZULU4's coatings keep contrast high and color true, so a red buoy reads red and a distant hull separates cleanly from the waterline behind it. When you're running an inlet or feeling your way into an unfamiliar harbor, that clarity is what turns a guess into a confident call.\u003c\/p\u003e\n\u003cp\u003eEvery detail here reflects a simple idea, that your optic shouldn't be the weak link when the water gets rough or the light gets tricky. You get a 60 degree apparent field of view, a twilight factor of 20.5 for solid low-light performance, and Schmidt-Pechan prisms that keep the package compact. At 26.7 ounces it's easy to carry all day, and the near focus of 1.8 meters means you can even study something close aboard.\u003c\/p\u003e\n\u003cp\u003eIf you're outfitting a center console, a sailboat or a bay boat and you want glass you can count on, the ZULU4 10x42mm delivers elite performance without the fuss. It's covered by Sig Sauer's reputation for building gear that holds up, and it's ready to ride along on every trip you take. We're glad to help you match it to the way you run your boat, so reach out if you have questions.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eHigh-definition glass delivers exceptional clarity and superior brightness for a high-resolution sight picture\u003c\/li\u003e\n  \u003cli\u003eProprietary anti-reflective coatings, SpectraCoat, LensArmor and LensShield, reduce glare and resist wear\u003c\/li\u003e\n  \u003cli\u003e10x magnification with 42mm objective lenses balances reach with hand-holdable stability on a moving boat\u003c\/li\u003e\n  \u003cli\u003eIPX7 waterproof and fogproof rated for rain, spray and humid conditions\u003c\/li\u003e\n  \u003cli\u003eReinforced magnesium housing wrapped in rubber armor for lightweight durability\u003c\/li\u003e\n  \u003cli\u003eRedesigned focus wheel with precision contour overmold for ultra-fine focal adjustment\u003c\/li\u003e\n  \u003cli\u003eLocking diopter ring holds your personal setting, plus two-position twist-up eyecups\u003c\/li\u003e\n  \u003cli\u003eTripod mount capable via standard 1\/4 inch by 20 threaded insert for long glassing sessions\u003c\/li\u003e\n  \u003cli\u003eIncludes molded EVA carrying case and neck strap\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sig Sauer reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eAre the Sig Sauer ZULU4 10x42mm binoculars waterproof?\u003c\/summary\u003e\n    \u003cp\u003eYes.
