The Knapsack Sprayer is our all-rounder. As opposed to many competing products, the Knapsack Sprayer provides some compelling advantages. Of particular note is the replaceable battery. This allows a nearly seamless use of the Knapsack as long as this is required (only by changing the battery). The standard version of the Knapsack sprayer comes with either one or two lances. In case you require a bigger spray radius, we offer telescopic lances.
