    The above chart show the pressure used and the % of driftables in various senarios for a chosen speed and application rate. Each filled cell indicates a possible combination of bubble jets. The colour & size above and to the left of each cell indicates the two bubble jets that can be used

    The twin cap gives an alternative application method by using two nozzles (either the same size or different sizes) in one cap.

    • Excellent spray coverage from front and rear jets
    • Faster speeds and higher volumes
    • Increased crop penetration and coverage
    • Ideal for foliage crops, potatoes and sugar beet
    • Easily assembled
