The Dramm 30" Rain Wand could potentially be used with a pocket hose as long as the fitting at the end of the hose matches up with the threads. The wand has a handle on it to control water flow at the wand, so you would not have to control it at your spigot.
This Dramm 30" Rain Wand is perfect for garden bed watering and container watering. It was originally designed for nurseries and greenhouses, it provides a gentle and full flow stream for flowers.
