Sounds like a promising nozzle. Any of you guys using them?
These have been available for at least 2-3 years. I have some, haven't used them though.

I tried them over a year ago and wasn't convinced of coverage... so I replaced them with 5 ft nozzles and turned them down a little.

Did they redesign them? Or is this just a marketing push? I got a postcard yesterday too.

Don't know. I got them just to have for a "quick fix". I would never design a system using these. For areas that small, SDI is the better option IMO.

The originals were called XPCNs (for Xeri Pressure Compensating Nozzles) and the flow was stated in gph... for instance:

In the "first" position @ 40 psi the H at 3.0 ft radius used 13.7 GPH and a precip. rate of 1.22 in/hr.

Yet at the "second" position @ 40 psi the H at 4.0 ft radius used the same GPH, but a precip. rate of .54 in/hr.

Both of these as laid out with no overlap.

I didn't really look at the post card yet to see whether these are the same thing or something different.
