Buying Guide

What to consider when choosing a backpack sprayer

• Tank capacity and design: A 4-gallon tank balances portability with enough volume for moderate tasks. Look for translucent tanks and wide openings for easy filling and cleaning.
• Pump type and pressure: Higher PSI supports dense coverage; choose piston or diaphragm options based on chemical use and area size. A lockable shut-off helps maintain consistent spraying.
