Hi there,
First post here.
I'm looking to set up nozzles in a fairly large lawn area where existing sprinkler heads are about 24 ft apart. I wonder which kind of nozzle would provide the following features:
- works w/ somewhat low water pressure (28-30 psi)
- provides adequately large coverage (24 ft for existing head-to-head distance)
- clean and good edge coverage
- does not require 100% head-to-head coverage (has nozzle head coverage already, i.e. no dry spots around the nozzle head)
- does not take too much time to provide adequate water precipitation
I've been using some Rainbird rotary nozzles but in practice w/ the low water pressure
- it barely covers enough (21 ft w/ current water pressure),
- seems to have some head coverage so doesn't require 100% head-to-head coverage so that's good
- coverage along the edge is poor -- spray length is very short when it gets close to the edge => dry spots along the edge. Only workaround is set wider arc => overspray.
- takes double the time to provide enough water for the lawn. For the front lawn alone it takes 5 hours.
I tried the Hunter MP Rotator MP3000 but the edge coverage issue is similar (much shorter length when close to the edge).
Any great ideas pls feel free to provide.
I've heard about Toro's Precision Spray Nozzle, but it'd only cover 15 feet -- not enough for my situation (24 feet required).
How about Toro Precision Stream Rotating Nozzle? Does it cover correctly along the edge--or not?

Or Rainbird rotors: 3500,5000 series?
Do gear-driven nozzles last just as long as non-gear driven nozzles? More maintenance (like debris/minerals)?
Thx.
