The Twin Expedition is the first single-handled dual ascender designed to meet the needs of industry leading arborist professionals. The EXPTWIN easily accommodates three rope techniques - 2:1 doubled rope technique (DdRT), 1:1 single rope technique (SRT), and 1:1 twin line ascent (DbRT). It is intuitive and easy to use, has redundant safety features, and is the first ascender on the market to use one finger to actuate both cams for one handed downward adjustability. One ascender, two handles!
