For accuracy, we recommend you follow the process without the presence of a saddle pad.
STEP 1) Place the saddle in riding position on your horse/pony's back and make a reference point directly under the saddle nail - we suggest you carefully separate your horse's hair as a marker.
STEP 2) Remove the saddle. Place the PE Gullet Gauge on your horse's withers, aligning the gauge with the reference point you made earlier.
STEP 3) Make sure the bearing area of the gauge rests comfortably against the horse. Make sure the gauge is clear of the horse's withers.
STEP 4) The tool will then indicate the color of the eyelet corresponding to your horse in the PE interchangeable eyelet range.
We recommend repeating this procedure every three or four months.
We recommend consulting a qualified saddler to adjust your saddle.
