DIG's 300 series adjustable micro sprayers are available with three different spray patterns that include full, half and quarter circle. They have an adjustable flow feature of 0 to 26.1 gph at 25 psi. The available models include 300B, 308B and 309B (packs of 2) with 10/32 thread and 300-1B, 308-1B and 309-1B (packs of 1), fully assembled with a 13 in stake, 12 in PE riser and 1/4 in barb. These micro sprayers have an adjustable knob that allows control of flow to reduce or increase the diameter or wetting area of the spray pattern. Used for residential gardens, flowerbeds, groundcovers, shrubs and trees, the adjustable micro sprayers are ideal for areas where low-flow overhead irrigation is desired or for areas where drip emitters or conventional sprinkler systems are not practical.
