How many different positions does the vari-nozzle have?

The vari-nozzle is designed with the capability to adapt to various operational needs by providing multiple positions for water discharge angle and flow rate. Specifically, it features three different positions, which allows the user to control the direction and intensity of the water stream effectively. This flexibility is essential in firefighting scenarios, enabling the operator to adjust the nozzle for optimal performance depending on the circumstances, whether they involve fighting a fire, cooling down a hot area, or performing a rescue.

The other choices indicate a different number of adjustable positions for the vari-nozzle, which does not accurately reflect its design and function in practical applications. Understanding how these settings on the vari-nozzle can be utilized effectively is key for a boat crew member dealing with emergency situations.
