There are three new Apex irons from Callaway: a player’s distance club called Apex 21 targeted largely at people with handicap indexes that run from 5 to 15; a player’s performance version dubbed Apex Pro 21 for golfers who range from +5 to 5 and a game-improvement offering known as Apex DCB, geared largely for those carrying indexes of 12 or more.
Each model is forged from 1025 carbon steel, and they all boast Flash Face Cups designed with the help of artificial intelligence in an effort to bolster ball speeds. The irons also use Tungsten Energy Cores, which allow company engineers to precisely position the center of gravity throughout the set, for better launch and more forgiveness on off-center hits. Another attribute they share is the use of urethane microspheres to help optimize feel and sound at impact.
But the Apex irons possess different features and performance attributes as well. The Apex Pro 21, for example, has up to 90 grams of tungsten per club, while the tungsten in the DCB version weighs in at 50 grams each. The DCB relies on a deep cavity back and enhanced sole width to provide the sort of forgiveness, easy launch and solid turf interaction wanted by golfers looking to take their games to the next level. In addition, the offset for those irons is described as “moderate,” with that for the Apex being “standard” and the Apex Pro “minimal.” The head shapes vary as well and run from compact to moderate to enhanced.
What works best all depends on a golfer’s level of play.
