Each Shooaway unit has an effective range of about 700mm-1 meter diameter. So one Shooaway is perfect for using by the BBQ or on a smaller 4 seater table to keep flies away.
Often two Shooaway’s if ideal as one can be used when cooking the BBQ food to keep flies off the BBQ food and the other can be used to keep flies away from salads and other nibbles being prepared in the kitchen. Then when the food is ready take both outside (or inside) and use on your outdoor picnic table.
Two Shooaways will normally cover off a standard 6-8 seater outdoor table and keep flies away from landing and walking on your food when eating.
