DESCRIPTION Why was the Explorer voted the 2018 Disc of the Year? Straight flight path and controlled glide, that’s what the Explorer brings. Designed to be the workhorse for all kinds of accurate fairway drives. This stable and versatile fairway driver is smooth out of the hand and has a clean stable flight. Opto sparkle is the same as opto, but with some glittery goodness sprinkled throughout the plastic.
