My Chapin 1949 sprayer came with 0.5 gpm and 1.0 gpm fan tips, and here I bought the 0.2 gpm and 0.1 gpm fan tips to fill out my rack. This has the finest droplets for my Chapin 1949 sprayer. It provides a steady consistent fan pattern that allows for deliberate complete coverage in a horticultural setting. When I compared this to the larger 0.2 gpm Chapin Brass Fan Tip nozzle, I had to make a few passes over a leaf with this, while the larger nozzle might cover a leaf in one pass. So this 0.1 gpm version is the best for getting 100% coverage because you're going to be much slower, while you waste less and examine your target more closely. The 0.5 gpm version that came with the sprayer puts out too large of a drop for a canopy, but is a good size for soil coverage or concrete. Like screwdrivers, you'll want one of each size if you're like me. At this price DoMyOwnPestControl is really fantastic.
