Well-balanced and shoulder pads were comfortable. Provided good coverage. I use it to maintain a 15-tree home orchard. Works well.


I have worked with hand-sprayers and backpack sprayers for nearly 50 years. I'd been buying a sprayer that cost approximately $120 and was marketed by a company that I'm very fond of for their power equipment. However, I could never get the 2nd year with their sprayer-I always had to buy a new sprayer. I found the Field King Backpack here at Forestry Suppliers about 4 years ago (perhaps 5 yrs. even) and the sprayer has never failed me.


I have used several different sprayers of this type, and I believe this is an excellent value. Not a lot of frills, but I have had no problems with it. It does not leak, and it is easy to maintain a consistent pressure. Everything works very well. I have used it for several months with no problems whatsoever. For a simple sprayer that is easy to assemble and maintain and does its job very well, this is well worth the money.
