Im looking at getting a split tank sprayer, 50 gal+ 50 gal, instead of a single 50 are 100. Id like to know if anyone has used one, and what are the benifits and drawback's. Im looking at this so I dont have to invest in 2 spray rigs. It will be mostly for pre and post in lawns, and flowerbeds. Im thinking I will have to spray pre and post on a lawn,and just pre in the beds, are on the next lawn.
