Toro 53817 3-Inch Pop-Up Fixed-Spray with Nozzle Sprinkler, 360-Degree, 15-Feet

The description is loosely written. The sprinkler can spray "up to 15'," correct? The spray radius is fixed, not the range, correct?

Are these 0 to 360 degree? & if so why when I order these do I recieve a mix of 3 and 4 inch sprinkler heads & they are all 180 degree?

3/4 or 1/2”?

Anybody measure the minimum spray distance?
