The ELF-31H is an upgraded version of the original J31, which earned a reputation as a reliable, cost-effective night vision binocular. The new model maintains that same affordability but raises the bar with a larger F1.2 lens, capturing more light for a noticeably brighter and clearer image.
It also features an anti-reflective coating on the optics to reduce glare and enhance contrast—making it easier to pick out details in low-light conditions. If you liked the J31, the ELF-31H is everything it was, only better.
