The Discraft ESP Zone GT takes the reliable overstable flight of the Zone and adds a Groove Top, a thumb track molded into the flight plate that gives your release something to hold onto. ESP is the grippy premium plastic that makes the groove feel locked in instead of slick.

Flight Numbers: 4 / 3 / 0 / 3

ESP on the Zone GT feels a little wider and taller in the hand than a standard Zone because of that groove, and a thumb settles right into it on both backhand and forehand grips. It is torque resistant, so a hard flick will not spin it out of your hand, and it breaks in slowly enough to hold its overstable flight for a long time.

Out of the box it flies close to the standard ESP Zone: torque resistant, moderate glide, and a reliable overstable finish. On hyzer it cuts hard and gives you the flare and skip you want on tight approach shots into the green. It sits between the softer Jawbreaker Zone and the stiffer standard ESP Zone in feel, which makes it a good pick for anyone who throws a lot of flexy upshots or works shots around corners on hyzer. New players get a disc that is hard to mis-release; advanced players get a groove that inspires confidence on the forehand.

Bag it next to this: the Discraft ESP Zone if you want the same flight without the groove. Want a deeper rim in the same flight? Check the Rubber Blend Zone GT. See the rest of our overstable putters.
