The String Measure
The string measure is ideal where the jack and bowls are too far apart for a box string measure to reach, or where the jack or at least one of the bowls is in the ditch. It’s a length of string wound around a reel at one end and a fixed pointer at the other end. There is a second (moveable) pointer that you can slide along the string that must have a lockable device to ensure that the measure does not slip once in use.
As an alternative, when a string measure is not long enough, a boundary string (shown right), modified by the addition of a fixed and a movable pointer, can be used instead. In countries where a boundary string measure does not form part of the standard equipment, the long tape should be used when a string measure is not long enough.
When using a string measure or a modified boundary string:
- Make sure you follow the Common Procedures for conducting a measure described earlier.
- Maintain communication with your assistant at all times.
- Have your assistant place the fixed end of the measure against the jack.
- Extend the string to the bowl.
- Check with your assistant that the pointer is just touching the jack and the string is in a straight line from jack to bowl before you set your measurement.
- Without altering the setting of the measure, check the measure from the jack to the second bowl.
- If the measure is to a jack or bowl in the ditch, make sure that the string crosses the ditch in a straight line between the jack and the bowl. Also, make sure that the string does not cut into the green at the point where it crosses the edge of the ditch.
