Electronic Measurement in the Horizontal Jumps – Mark Heckel – 2010  - Page  7 

Move the spotting laser to the second checkmark, read and verify the 
distance. 

As an in-event checkmark, pick a distance that you can quickly move the 
spotting laser to. Place a small marker, such as a small piece of tape, on the 
ground outside the landing area that will not be disturbed. This can serve as 
a checkmark during the competition.  

Record this distance on a separate sheet of paper. Between flights or 
between trials and finals, you can move to the check mark and verify that 
the beam has not moved. 

Measuring the landing mark 

1.

 

Once the athlete has exited the pit, insert the stake into the sand. Make 
sure the stake is placed so the middle of the white tape is inside the 
depression made by the jumper, rather than in front of the depression. 
The tape must be on the side facing the guide rail. 

2.

 

Slide the scope carriage down the rail until the spotting scope beam is 
aligned with the edge nearest the take-off board of the white line on the 
stake. Once it is aligned, step back from the rail. 

3.

 

Record the distance with the measuring laser. Press the 

On/Dist

 button 

to turn the laser on. 

4.

 

The screen will display three hashes, signifying the laser is on and ready 
to take a measurement.
