Scientific Anglers' notable developments include the introduction of PVC coated designs of contemporary floating fly lines in 1952 and the development of sinking fly lines in 1960. Their introduction of PVC coated  fly lines was largely responsible for the decline of the old line sizing system that used letters—HCH—to designate the taper and weight of silk fly lines. Because PVC coated lines were significantly different from silk lines, a new system evolved that identified lines with their grain weight in the first 30 feet of line (i.e. 5 wgt) and a two letter designation—DT (Double Taper), (ST-Single Taper) or (WF-Weight Forward) to identify the line taper. Scientific Anglers is subsidiary of Orvis, and currently has a design lab in Midland, Michigan.
