Introduced in 2000, the AirMix nozzle was developed to provide a low pressure entry level Venturi nozzle, primarily with the European market in mind.

2005 saw the introduction of the TurboDrop TwinFan nozzle using a TwinCap with two different spray tips to deliver medium and fine droplets. In 2007 the TurboDrop Variable Rate nozzle was released as both a single fan and twin fan model to deliver three times the flow rate range. A streaming fertilizer version was released in 2009. The TurboDrop Asymmetric DualFan nozzle (TADF) became available in April 2011. This full season nozzle uses an alternating configuration on the boom to deliver four spray angles in one pass.
