What method is recommended for calibrating a spot gun?

The method recognized for calibrating a spot gun is the 20 squeeze method. This technique allows operators to determine the amount of pesticide being delivered per squeeze of the trigger. By consistently squeezing the trigger 20 times and measuring the total volume dispensed, one can easily calculate the flow rate. This is particularly useful for ensuring that the application is both accurate and efficient, as it allows for adjustments to be made based on the specific requirements of the task or the characteristics of the pesticide being used.

The 20 squeeze method is straightforward and enables the applicator to maintain control over the application rate, which is essential for effective pest management and promoting environmental safety. Proper calibration ensures that the correct amount of pesticide is applied to the target area, minimizing waste and reducing potential harm to non-target organisms.

Other methods, while they may have their own applications, do not specifically provide the same level of ease and accuracy for calibrating a spot gun as the 20 squeeze method.
