The new PVS-31C-MOD is a dual-tube goggle system with more ergonomic design and improved functionality. It accommodates features such as a dedicated Instant-On-IR button to quickly and momentarily engage IR illuminator without having to operate the switch. The connector located at the front of the unit is used to supply power to the unit from almost any power source: external battery pack, USB power bank, 12V car socket and so on.
