What Your Divot Is Telling You About Your Strike

Most golfers walk past the best coaching aid on the course without looking at it. Every iron shot leaves a mark in the ground, and that mark records exactly where the club reached the bottom of its arc. You do not need a launch monitor to read it — you need to stop and look before you put the divot back.
The divot should start after the ball
This is the one that matters most. With an iron, the ball is struck first and the turf second — the club is still travelling downwards when it meets the ball, and only reaches the ground beyond it.
If your divot begins behind the ball, you are hitting the ground first and the ball is getting whatever energy is left. That is the fat shot, and it is a low point problem, not a swing problem.
“A divot is not damage. It is a printout of where the bottom of your swing actually was, and it does not lie to make you feel better.”
Depth tells you about shaft lean
A shallow divot the depth of a bank note is what you are after. Deep, narrow gouges usually mean too much forward shaft lean and a steep angle of attack: the club is digging rather than sliding.
The fix is rarely "swing shallower". It is usually pressure — get your weight moving to the lead side earlier in the downswing and the club has room to travel forward as well as down.

Direction exposes your path
Now look at which way the divot points. A divot aimed left of your target line with a straight-ish ball flight means an out-to-in path — the same path that produces a slice when the face is open to it.
A divot pointing well right of target suggests the opposite: an in-to-out path, which is where blocks and hooks come from.
Take a photograph of three or four divots the next time you practise. Patterns show up across a session that you will never spot on a single swing.
Where to go next
Read the divots before you change anything. Most players arrive at a lesson convinced they have a swing fault, when what they actually have is a low point that moves around from shot to shot.
