🔧 PVS31 — Pro vs Standard (Differences & Highlights)

PVS31 Digital Night Vision Device Gen.4 0.39 Pro — Upgrade

【New compared to the standard version】

1. Independent housing power supply
2. Brightness control function
3. Switching between green and white phosphor display
4. Highly integrated control switch

【Device highlights】

1. Highly integrated switch: The Pro model has been revised based on the FMA model. Unlike the standard three-stage switch, the Pro version uses a single highly integrated switch that controls all functions: On/Off, IR illumination, colour switching and brightness control. The external appearance and battery cover remain undamaged — no additional drilling is required. The battery pack is conveniently charged via a modern Type-C port, so you don’t need a separate charging adapter when travelling.
2. Robust, integrated design: The internal wiring is routed inside the housing without removing critical axles (no weakening of the housing structure). Protection class: splash-proof for everyday use. The device also features a true 18× optical eyepiece (not cheap acrylic), dioptre adjustable and therefore suitable for glasses wearers. Objective and eyepiece are removable for easy cleaning and maintenance.

Battery difference

The Standard Version uses an external battery box as its default power source. The Pro Version can be operated both with an external battery box and independently with a single 14500 (3.7V) pointed cell directly in the housing.

⚠️ Notes / Safety

• When charging the battery pack, ideally avoid fast smartphone chargers, as excessive power may damage the battery.
• For independent housing power supply, a single 14500 (3.7V) pointed cell is required — insert it with the positive pole facing outwards. Caution: never insert incorrectly. If the battery casing is damaged, remove the battery from use immediately.
• A blue screen or vertical stripes indicate low battery — not necessarily a defect; please recharge in time.
• Switch off IR illumination when idle to avoid overheating or damage.
• Use only the supplied battery box or approved battery types for power supply — do not use foreign power sources.
