Capacity Matters

When I was selecting my sprayer, I considered the tank capacity. The Field King Backpack Sprayer usually offers different sizes, and I opted for one that holds around 4 gallons. This capacity allows me to cover a large area without needing constant refills, making my gardening sessions much more efficient.
