Five-Year General Warranty

Quad Defense warrants qualifying new QDEF-built night vision systems against defects in materials and workmanship under normal use for five (5) years from the original date of purchase.

The QDEF warranty applies to the complete system as provided by Quad Defense, subject to the component-specific warranty periods, manufacturer coverage, limitations, and exclusions described below.

If a covered defect is confirmed during the applicable warranty period, Quad Defense may, at its discretion:

• Repair the affected product or component
• Replace the affected product or component
• Provide another appropriate warranty remedy when direct repair or replacement is not reasonably available

Warranty service is intended to restore the product to proper operating condition. Warranty coverage does not automatically create eligibility for a refund, return, upgrade, or replacement with a higher-value product.

QDEF Remains Your Support Point

Our support does not end when the system leaves the bench.

If a QDEF-built system develops an issue, contact Quad Defense first. We can help determine whether the issue falls under the QDEF five-year warranty, an image intensifier warranty, a housing manufacturer's warranty, or another applicable manufacturer warranty.

Where a manufacturer provides coverage beyond the QDEF warranty period, Quad Defense will continue to assist and support our customers through the applicable manufacturer warranty process.

Manufacturer warranty claims remain subject to the manufacturer's current eligibility requirements, exclusions, repair policies, replacement policies, and parts availability.

Manufacturer Housing Coverage

Many of the housings offered by Quad Defense include manufacturer warranty coverage in addition to the QDEF five-year general system warranty.

That coverage follows the housing and the manufacturer's applicable terms. Where qualifying manufacturer coverage remains in effect, Quad Defense will help support customers through the warranty process.

Tube Warranty Periods

Image intensifiers are specialized components and their applicable warranty periods vary by manufacturer.

Systems Built by Other Manufacturers

New factory-built systems sold by Quad Defense but manufactured by another company are generally covered by the original manufacturer's warranty unless otherwise stated.

Specific manufacturer warranty periods may be listed on the applicable product page or in documentation supplied with the product.

Quad Defense will assist customers who purchased the system from us with identifying and navigating the appropriate manufacturer warranty process when reasonably possible.

30-Day Limited Warranty

Qualifying pre-owned night vision devices sold by Quad Defense include a limited warranty for thirty (30) days from the date of purchase.

This limited warranty covers devices that arrive non-functional or experience a qualifying defect determined to have existed at the time of sale.

The pre-owned warranty does not cover damage or failure resulting from misuse, accidents, neglect, improper operation, unauthorized modification, or other causes occurring after delivery.

What Is Not Covered

The QDEF warranty does not cover damage, degradation, or failure caused by conditions outside normal intended use or by actions unrelated to a defect in materials or workmanship.

Examples include:

• Improper use: use outside the product's intended purpose or operating conditions.
• Physical damage: drops, impacts, crushing, abuse, accidents, improper mounting, or other external damage.
• Improper light exposure: damage caused by prolonged or excessive exposure to high-intensity light sources, lasers, weapon lights, or other conditions capable of damaging an image intensifier.
• Battery-related damage: battery leakage, corrosion, improper battery type, improper installation, or damage associated with long-term storage with batteries installed.
• Unauthorized repair or modification: damage caused or contributed to by improper disassembly, alteration, repair, modification, or service.
• Neglect or improper care: failure to reasonably maintain, store, operate, or protect the equipment.
• Operation outside specifications: use outside applicable environmental, electrical, temperature, or other operational limits.
• Altered identification: serial numbers, labels, or identifying markings that have been removed, altered, destroyed, or intentionally made unreadable.
• Normal wear: ordinary cosmetic wear or deterioration that does not constitute a defect in materials or workmanship.

Special-Order & Discontinued Products

Special-order, legacy, or discontinued products are not automatically excluded from warranty coverage solely because they are special-order or discontinued.

However, available remedies may depend on replacement-parts availability, continued manufacturer support, compatible components, and whether an equivalent replacement product remains available.

When the original component can no longer reasonably be repaired or replaced, Quad Defense will determine the appropriate remedy based on the applicable warranty terms and available options.

Transferring the QDEF Warranty

A qualifying Quad Defense warranty may be transferred to a subsequent owner after verification and inspection by Quad Defense.

How to Start a Claim

If you believe your equipment has a covered issue, contact Quad Defense before shipping the device.

Please provide as much of the following information as possible:

• Original Quad Defense order number
• Device model
• Device serial number
• Image intensifier serial number(s), when available
• Description of the problem
• Photos or video showing the issue when helpful
• Information about when and how the problem occurred

Quad Defense may request additional information before issuing return authorization or determining whether the product should be inspected.

Do not ship equipment to Quad Defense without authorization.

How Warranty Issues Are Evaluated

Warranty eligibility may require inspection of the equipment to determine the cause of the reported issue and whether the failure falls within applicable QDEF or manufacturer warranty coverage.

The presence of a problem does not automatically mean the issue is a manufacturing defect. Equipment may need to be evaluated for physical damage, environmental exposure, electrical issues, component failure, maintenance history, improper operation, or other factors relevant to the reported condition.

If the issue is not covered under warranty, Quad Defense may provide available service or repair options when appropriate.

Additional Terms

Except for the express warranties described on this page and to the extent permitted by applicable law, Quad Defense disclaims other warranties, whether express, implied, statutory, written, or oral, including implied warranties of merchantability and fitness for a particular purpose.

Manufacturer warranties referenced on this page are provided by the applicable manufacturer and remain subject to that manufacturer's current terms, conditions, limitations, exclusions, and warranty procedures.

Quad Defense's assistance with a manufacturer warranty claim does not expand, modify, or replace the manufacturer's warranty obligations.

Nothing in this warranty is intended to limit any right or remedy that cannot legally be excluded or limited under applicable law.

This warranty provides specific legal rights, and customers may also have additional rights that vary by state or jurisdiction.
