WEEDitimproves at night because there is lessinterference from sunlight and weeds areoften less stressed meaning the reaction tochlorophyll is greater. Unlike other makesof weed detection equipment, the WEEDitsystem also utilises a speed sensor toincrease or decrease the reaction time ofthe nozzles, meaning a more accurate andefficient job across the paddock.BACKGROUND CALIBRATIONChanges in background conditions is asignificant issue for other makes of weeddetection equipment, mainly causedby changes in soil type and stubble.The WEEDit is inherently less sensitiveto changes in background conditionsbecause it is only measuring chlorophyll,and background calibration happensautomatically For the operator this meansless downtime and ultimate performanceacross the entire paddock.WEEDitSENSOR AND NOZZLE PLACEMENTWEEDit sensors are placed every 1 metreacross the boom and control 5 nozzles(individually) on 20cm spacings. Benefitsfrom this design are less weight dueto less sensors being required, and asmaller spray footprint when a weed issprayed. This set-up provides greatersavings on chemical compared to othermakes of weed detection equipmentavailable in the market. The nozzlespacing of 20cm also allows for anarrower angle nozzle to be used withthe benefit of reducing spray drift.ENHANCED ELECTRICAL SYSTEMAny weed detection system places largedemands on electrical supplies. TheWEEDit overcomes this issue by runningat 48 volts. This not only gives superiorsolenoid operation but current draw is4 times less than other weed detectionequipment using 12 volt systems. Fastersolenoid operation also means quickerspraying speeds in the paddock.SUPERIOR PRODUCTIVITYThe WEEDit system provides high speedoperation of up to 25k/hr which is up to10k/hr faster than other weed detectionunits in the marketplace. High speedoperation gives you greater productivityand better utilisation of your investment.22
