Tasco, also known as Tasco Worlwide, was founded in 1954 and is a child-company of Tasco Holdings, Inc (THII). Tasco, based in Miramar, Florida, was founded in 1954 by George Rosenfield as the Tanross Supply Company, a distributor of fishing tackle and hardware. The name was later shortened to Tasco as inventory expanded to include binoculars and eyepieces. Tasco is now one of the major international distributors of telescopes. The company's products mainly target amateur telescope buyers in astronomy, but has grown to manufacture a large assortment of optical equipment, including terrestrial spotting telescopes, microscopes, binoculars, rifle scopes, and other rifle accessories. Tasco products can be purchased through a variety of specialty outlets, catalogues, and online vendors.
