An equalizer trigger is a special trigger seen only on the Buzz Bee Water Warriors Power Shot blasters.
Note the white tab on the Power Shot's triggers. That is to switch between the 2 modes.
They are essentially squirt gun triggers with a little switch than can be toggled between normal and power shot mode. When on normal mode, it behaves like a regular squirt gun trigger, but when on power shot mode, the trigger is a little hard to squeeze, but results in slightly better performance.
