Frequently Asked Questions

What is the Infiray Jerry-31 and what makes it notable in the night vision market?

The Infiray Jerry-31 is a Chinese-made binocular night vision device that represents a more affordable entry into the analog night vision market. It utilizes NNVT Gen 2+ white phosphor tubes and is designed to offer dual-tube depth perception at a lower price point than many US-made alternatives.

What are the main cost-saving factors in the Infiray Jerry-31 compared to higher-end night vision?

The Jerry-31 saves costs by employing NNVT Generation 2+ intensifier tubes instead of more expensive US-made Generation 3 tubes, and by using smaller, lower-quality objective and ocular lenses which can also lead to more noticeable chromatic aberration.

What are the key features and potential drawbacks of the Infiray Jerry-31's auto shut-off function?

The Jerry-31 features an automatic shut-off for its pods when articulated upwards. However, the accelerometer-based system is noted as unreliable during movement, potentially causing flickering or unintended shut-offs, leading experts to recommend disabling it for serious use.

How does the optical quality of the Infiray Jerry-31 compare to other night vision devices?

The Jerry-31 uses smaller lenses than standard PVS-14s, requiring closer eye relief for a full field of view. These lenses also exhibit more significant chromatic aberration, particularly in the peripheral view, compared to higher-end optics.
