Good with the right battery. - VECTRONIX SHOOTING SOLUTIONS Vector X 42 MSR-DMR 10x42mm Rangefinding Binocular

The glass is as clear as any high end binoculars I've used, software and UI are great with unparalleled ranging. The only issue I had was with the included Panasonic CR123, it only ranged once then the device would just turn off from what I assume was voltage drop. I tried with other good CR123 batteries that I use for my thermal scopes and had the same issues. Luckily I also have a Streamlight that uses rechargeable batteries and those worked fine. I'd recommend investing in Paleblue USB-C rechargeable CR123s or 18650s as the included battery is likely to let you down in cold weather.
