Electronic Measurement in the Horizontal Jumps – Mark Heckel – 2010 - Page 9
When the competition is over
Even though you have periodically checked your check mark, you should
repeat the process that you used in setting up. Run the steel tape out
parallel to the lane boundary, and measure the same points that you
measured during the setup process. Your measurements should match.
Notes:
•
Be sure to have a couple of towels available to cover the spotting laser and
the measuring device between rounds, especially in wet or sunny
conditions.
•
You will also need some type of lubricant for the beam. Depending on its
material makeup, silicon or WD-40 will work very well.
•
You may need to periodically wipe down the beam, as sand and grit will
tend to accumulate on it.
•
Green lasers work best for outdoor competition, while red lasers tend to
work best for indoor competition.
•
Have a tablet or small notebook to record your setup measurements and
your checkmark measurement.
•
A small torpedo level should be part of your kit to check the level of the
beam.
•
Have some wood shims in case they are needed to level the beam.
•
A steel tape of at least 25’ (long jump) or 50’ (triple jump) should be used.
Normally, these are part of the horizontal events crew bag.
