Overview
An OLED display lens and a manual focus ring drive this Goyojo monocular, which clips to a helmet through a mount with a compass. It runs on lithium polymer batteries and has an infrared illuminator.
A wide view and several color modes make it useful for moving through dark terrain. The charger, bracket, screws and manual are all included. The listing says nothing about water resistance or detection distance.
Who it's for
Someone walking or working at night who wants both hands free and a wide view. A buyer who will use it at long range should look for a model that lists detection distance.

Performance notes
