Combine Binoculars

The spotting scope is an object that temporary Combine soldier encampments use to scope out faraway areas.

Appearance
The spotting scope is a black, tripod-mounted scope with a shimmering blue lense set into a small, compact set.

G-Man
In chapter 7: Highway 17 of Half-Life 2, one spotting scope can be found in an abandoned shack being used by three Combine soldiers as a camp. When one clears out the soldiers, then looks through the scope, they can see one of the most elusive, and arguably, most interesting, G-Man sightings in the game; the G-man conversing with Colonel Cubbage at the New Little Odessa.
