SPRINKLER ZONE CALCULATOR

The Hunter Sprinkler Zone Calculator is your all-in-one tool for calculating flow and zone capacity. It guides you through nozzle selection using built-in performance charts and helps you determine the ideal sprinkler head quantity to maximize flow.

This tool calculates one zone at a time.
