8 iron distance at 55 mph

A 8 iron swung at 55 mph carries about 96 yards and totals 100 yards on the published tour table, with a smash factor of 1.26 and 69 mph of ball speed. The tour average for the club is 87 mph and 160 yards of carry, so 55 mph sits -32 mph and -64 yards from it.

The number

Ball speed is club head speed multiplied by smash factor: 55 multiplied by 1.26 is 69 mph. Carry is ball speed multiplied by the club’s 1.39 yards per mile per hour from the published tour row: 96 yards. Roll adds 4 percent on a fairway landing, for 100 yards total. The smash factor sits 0.06 below the tour value of 1.32 because the model eases strike quality by 0.01 for every 5 mph below the tour speed.

What strike is worth

At 55 mph a strike that moves smash factor by 0.02 moves ball speed by 1 mph and carry by about 2 yards with a 8 iron. Speed is the expensive way to add distance; strike is the cheap one, and a launch monitor session shows which of the two is limiting yours.

The rest of the bag

A golfer who swings a 8 iron at 55 mph swings a driver at about 71 mph on the model, since every club runs at the same fraction of its tour speed. That driver speed maps to about a 36 handicap on the handicap model and beyond the oldest band on the age model. The bag below is every club at that fraction.

In PinFlag

Import a launch monitor session and PinFlag turns your 8 iron into a pattern of your own carries, labeled Measured, that stands behind every target you price on the course. Shot Cloud draws the real shots around the spot you are considering, on the hole in front of you, so a tucked pin is compared with the middle of the green on your real spread, not a single yardage.

Every shot you log with the 8 iron on the course records the target and the result, so the pattern keeps growing from real rounds, and Insights shows the club’s proximity, the shots it cost and the shots it won across a season.
