As William Ainsworth Inc., production of the Pocket Transit™ continued; the same basic design remains in production today, in numerous versions and configurations. In 1970, the company introduced the Brunton Cadet, a simplified evolution of the Pocket Transit incorporating a compass and clinometer, intended for use in training students in the fields of geology, forestry, mining, and surveying. The company soon began marketing the Cadet to instruct Boy Scouts in the principles of surveying. In 1972, the newly formed Brunton, Inc. began compass and transit production in Riverton, Wyoming. Compasses included the Pocket Transit, Cadet, and an emergency compass called the Life Card, designed to float in a bowl of water. This was followed in 1981 by the Model 8040 Sportsman's Compass™, a map (baseplate) compass with folding cover and mirror sight. In the same year, Brunton introduced the Model 9020. This small baseplate compass was designed for hikers, outdoorsmen, and hunters. Over the next ten years, Brunton would introduce a full range of map or baseplate compasses based on a liquid-filled vial with no-tools adjustment for magnetic declination. This new line included Models 8010, 8020, 8040, 9020, and the compact 9030 Trailbuster. Brunton baseplate compasses with a G suffix (i.e. 9020G) featured bright 'optic green' acrylic baseplates combined with a 'deep well' capsule and top-hat mount needle pivot in order to function in most magnetic zones. Brunton often included UTM and map scales with these compasses for U.S. standard 1:24,000 and 1:62,500 USGS topographic maps. The Model 9030 Trailbuster™ was intended to replicate the popular Boy Scout Trailblazer pocket compass discontinued by Taylor Instrument Co. The 9030 omitted the usual acrylic baseplate in order to minimize bulk (it weighed only 1 ounce), yet could still be adjusted to hold a set course or take bearings from a map. In 1991, the U.S. military purchased a number of Brunton Model 8010 Smoke Chaser™ compasses originally produced for U.S. Forest Service fire-fighting crews. Assigned an NSN stock number, the compasses were stocked in survival kits for U.S. Navy and Marine flight crews. These Model 8010 compasses used clear baseplates and were equipped with lanyards. The compasses were shipped in plain cardboard boxes with military stock number NSN 6605-00-553-8795. Brunton discontinued all 8000- and 9000- series compasses in 2011. After being acquired by Silva, Brunton began selling Silva of Sweden compasses and GPS devices. The Brunton 'Nexus' line included the Silva Model
