Wow, I tried out my new battery powered Jacto sprayer today spraying for PLC. What a huge improvement over my pump sprayer!
Pro: high pressure flow throughout spraying, great coverage, easy to carry, no pump lever pieces to break
Cons: only holds 2 gallons so need to refill
As a wimp, I was never able to wear 4 gallons of spray as a backpack. 2 gallons over the shoulder is easy
One thing I noticed was that when I was using the hand pump I consumed a lot less spray - because I wanted to get through spraying as fast as possible. So not good if you start daydreaming while holding down nozzle of battery sprayer!!
