The reusable Sure Shot ® Steel Sprayer has a 32 oz. liquid capacity and features metal construction and corrosion resistant working parts. Fill the unit 2/3 full with solution and pressurize to 80-150 P.S.I. with any standard air chuck. You can also use the optional CO2 Pressure Charger Device and the CO2 Charger Bulbs to pressurize in the field. The trigger-operated sprayer emits an ultra-fine mist, which is ideal for latent print development.
