The Acer XV Pro iron heads feature the same cutting edge design as the Standard XV heads but are a slightly more compact design and have the reduced offset desired by better golfers. They feature a deep undercut cavity for great forgiveness. These heads have a slightly narrower sole and a thinner topline than the Standard irons. Enhanced heel-toe weighting enables the player to hit more solid shots. This is a great premium iron head offering by Acer for the low to mid handicap golfer.
