The new HyperSonic ”V” Fine Tune iron features 2 weight ports in the heel and toe to accommodate 8 gram tungsten screws (optional) to increase MOI for maximum forgiveness. This fine-tuning allows a golfer who e.g. makes contact on the toe side, to place more mass in the toe port for improved stabilization at impact. Each iron head comes standard with two 2-gram brass screws.

Deep undercut cavity moves Center of Gravity farther back and low.
