Why HDZero Goggle 2 Costs More — And Why It’s Worth It

HDZero Goggle 2 adds meaningful upgrades that enhance performance, durability, and convenience:

• Improved Optic Module – Now dust-resistant and redesigned for greater image clarity. This upgrade involves injection model tooling modifications and raises production costs, yet it results in a sharper, more refined viewing experience.
• Built-in High-Sensitivity Analog Receiver – No need to buy a $50 analog expansion bay or a separate analog receiver (often $80-160+).
• Integrated WiFi Mirroring – Effortlessly mirror your FPV feed to a phone or PC with no extra gear.
• Included Hard Shell Case – A $20 value included to protect your investment in transit and storage.

Together, these upgrades offer more than $150 in added value, while the new optic module significantly improves your day-to-day flying experience. The price increase reflects both the added features and the higher manufacturing cost — and we believe it’s a solid upgrade for any pilot.

OLED Display Disclaimer

Due to the nature of OLED technology, the presence of dead pixels is not uncommon and may occur during manufacturing. Please note the following guidelines:

• Single dead pixel: This is considered normal and does not affect product peformance.
• Two consecutive dead pixels (in any direction--horizontal, vertical, or diagonal): Acceptable if the total number does not exceed four instances.
• Three or more consecutive dead pixels (in any direction): This is considered abnormal and may qualify for warranty evaluation or replacement.

OLED displays can provide more vivid colors than traditional LCD panels, however, if they are displaying the same content for an extended period of time, it may come across issues like "image retention" or "image burn-in".

Warranty evaluations and returns for these tems must be handled through HDZero's support and warranty process. If a return or warranty claim is warranted, Five33 can assist in coordinating communication with HDZero to help facilitate resolution.
