The Heavy Duty Impact Sprinkler with 5 lb. weighted sled base is a great choice for general use on large areas where you need the sprinkler to operate continuously in a full circle.

It comes with two nozzle sizes, 4mm and 5mm to accommodate a flow range of 3 to 10 gallons per minute and up to 90+ feet in diameter! Applications include large yard areas, vegetable or flower gardens, orchard or shrub areas, and much more! Again, this is not a Heavy Duty Brass Impulse Sprinkler that you will find in local stores and is a great value for the price!
