Mr. Osborne also designed the photo-recording transit for making panoramic records of forest conditions, as well as a collapsible water-bag knapsack for firefighting (patented in the US in 1935). Many fire finders were manufactured from 1920 through 1935, but the manufacturer, Leupold & Stevens, Inc., stopped production of replacement parts ...
From these fire towers, using an instrument called the Osborne Fire Finder, or an alidade, and topographical maps, trained fire observers are able to spot and triangulate the location of possible wildfires. After ascertaining the location, the observer will file a "smoke report" which will be investigated and appropriate action taken by a local ...
A fire lookout tower, fire tower, or lookout tower is a tower that provides housing and protection for a person known as a "fire lookout", whose duty it is to search for wildfires in the wilderness.

Once a possible fire is spotted, "Smoke Reports", or "Lookout Shots" are relayed to the local Emergency Communications Center (ECC), often by radio or phone.

This is a list of notable fire lookout towers and stations, including complexes of associated buildings and structures. This includes lookout cabins without towers which are perched high and do not require further elevation to serve for their purpose, and also includes notable lookout trees .
Coincidence rangefinders were important elements of fire control systems for long-range naval guns and land-based coastal artillery circa 1890–1960. They were also used in rangefinder cameras. A stereoscopic rangefinder looks similar, but has two eyepieces and uses a different principle, based on binocular vision. The two can normally be ...
