Placing pins is done by "feel" and experience. Typically, a greenskeeper lets the weight of the cup cutting tool dangle so that gravity makes it vertical and plumb. Then the greenskeeper twists the handles to slice the round cutting cylinder into the green while trying to keep the tool in a vertical position. After the tool cuts in, it lifts a cylindrical core out of the new hole. This core of soil is saved to repair the old or previous hole after the cup is snagged and lifted out. Once the old hole is plugged with the soil and turf core, the greenskeeper places the cup into the new hole.
