These sprayers are very similar with the main difference being the handle function. The 7-Function Spray Gun
has a trigger whereas the 8-Pattern Flow Control Spray Gun
has a lever, which seems to experience fewer problems. Both are similar in terms of function, with six functions in common including the Centre, Flat, Cone, Shower, Full and Fine Mist functions. The 7-Function Spray Gun also has a Jet Spray function, and the 8-Pattern Flow Control Spray Gun has a Vertical and Stream function.
