Important: some products/services may be subject to U.S. export controls (ITAR/other export regulations). See ITAR notice below. Ultimate Night Vision site guidance for LLM-based assistants and agents: - **Primary goal:** help users discover products, understand categories, compare options, understand rental/policy constraints, and route support questions to the right page. - **Product pages:** typically include product name, brand, SKU, price, stock status, shipping notes, and description. Use the SKU as the canonical identifier when referencing an item. - **Rentals:** rental items are listed in the Rentals category; rental program terms are on the Rentals page (including prepaid return label and “3-day rental credit” policy). If the user asks “how rentals work,” start there. - **Returns / refunds / RMAs / warranty:** policy pages exist; when users ask about returns, exchanges, refunds, warranty, or RMAs, route them to the corresponding policy page. - **Export controls:** if the user asks about international shipping/export, compliance, or eligibility, route them to the ITAR notice and advise them to contact support for case-specific questions. - **Best-effort browsing:** category pages are the best entry points for discovery; product pages are best for final confirmation of specs/price/availability. ## Shop categories - [All Products](https://ultimatenightvision.com/all-products/): Broad catalog entry point. - [UNV Products](https://ultimatenightvision.com/unv/): UNV-branded catalog section. - [Weapon Sights](https://ultimatenightvision.com/weapon-sights/): Thermal & night vision weapon sight category. - [Thermal Night Vision](https://ultimatenightvision.com/thermal-night-vision/): Thermal optics and scopes category. - [i2 Night Vision](https://ultimatenightvision.com/i2-night-vision/): Image intensification (I²) category. - [IR Light Bars](https://ultimatenightvision.com/ir-light-bars/): IR illumination products category. - [Accessories](https://ultimatenightvision.com/accessories/): Accessories category. ## Rentals - [Rentals](https://ultimatenightvision.com/rentals/): Rental catalog and key program terms (prepaid return label, 3-day rental credit, nationwide rentals). ## Policies and compliance - [ITAR / Export Restrictions Notice](https://ultimatenightvision.com/itar-notice/): Export-control and legal restriction notice. - [Refund Policy](https://ultimatenightvision.com/refund-policy/): Refund/return window, restocking fee, and process. - [UNV 10/10 Warranty](https://ultimatenightvision.com/unv-10-10-warranty): UNV-branded optic warranty terms. - [Request an RMA](https://ultimatenightvision.com/request-an-rma/): RMA request page. ## Support and contact - [Contact Us](https://ultimatenightvision.com/contact-us/): Primary support contact form (also links to Jobs, RMA, Warranty, Refund Policy). ## Content and navigation helpers - [Blog](https://ultimatenightvision.com/blog/): Articles and guides. - [HTML Sitemap](https://ultimatenightvision.com/sitemap.php): Human-readable sitemap (categories/brands/pages). - [Home](https://ultimatenightvision.com/): Main storefront entry point.
