Had our demo this morning on the new I-35 field sprinkler and it's quite interesting but I'll post more on it later this evening or by this weekend. Had the chance to see the PGP blue nozzle in operation right next to a PGP with the red nozzle so we could see the difference. Seems that the blue nozzle does have the "curtain effect" but would have to see a zone difference. We don't use the PGP so I don't have any zones to compare overall watering effectiveness. One of the interesting things brought out about the PGP is that Hunter will be putting out the PGP-B soon and the only difference is that those sprinklers will have nothing but the blue nozzles in their cases. They'll still manufacture the red nozzles for their "standard" sprinkler cases with a few trees of the blue nozzles included in each case. Guess they've had enough contractors wanting only the blue nozzles so they'll accomodate them with the new packaging so they don't have to ask for the nozzles and have to rely solely on their suppliers. At the present time there appears to be no plans to stop making the red nozzles and they will let the market drive the nozzle differences.
