Im switching guns so that when i apply the dye that it will look more uniform and not splotchy.... what tip do you guys prefer to cover the best area?
The usage of dye was a step in arriving at what equipment would apply a treatment evenly to a turf area, providing good coverage without run off from the target weeds. Even on a hand piece using a single tip, my preference is for an Air Inducted flat fan. A 11008AI operated at 40 PSI at a moderate walking pace of 2 MPH held 18" off the ground will apply about 2 gallons per 1000. A 11004AI will apply 1 gallon. Dye was also useful in determining what set up favored off target deposition of the spray. A non air inducted flat fan nozzle or even a flood jet nozzle had lots of dye on me, landing in flower beds or on hard surfaces.
