I have been through a variety of handheld sprayers for herbicides in the past, real tired of leaking cheap crap but don't want to break the bank either. I was thinking backpack since I have 1/4 mile drive to epray. No battery operated nothing fancy -just want to spray without getting it on me or wasting expensive product. Didn't find where this had been discussed here. What is your experience and reccomendations? Thanks!
