Electronic scoring system

Electronic scoring systems or electronic targets are automated scoring systems used for sport shooting where the shot placement and score is automatically calculated using electronics and presented on screens to the organizer and shooters. The score may also be shown on a big screen for audience at the shooting range, and this has in many ways revolutionized the shooting sport.

With traditional paper targets the audience has to understand the signals used for scoring, and perhaps managed to monitor the scoring of maximum two targets at once, while with electronics the current scores can be shown on big screens only fractions of a second after the shot is fired and the audience can easily see how different shooters compare to each other. Some systems even allow real time publishing on the internet. The scoring can also be held back by the Range Officer until the string of fire is finished, so that scores for each competitor can be shown in ascending order.

Electronic targets are used for all types of sport shooting ranging from 10 meter air rifle to over 1000 meter long range shooting competitions, for "running targets" (moving on rails) like the ISSF 50 meter running target or "Running Moose" competitions (popular in Scandinavia), and electronic knock down targets are also used for sport shooting and by many militaries. Targets are available for calibers ranging from air gun pellets up to the 105 mm tank shell.

Some advantages of electronic scoring systems are:

Some disadvantages of electronic scoring systems are:

All types of electronic targets use some form of trigonometric equations to triangulate the position of bullet impact.

Sound-chamber targets is the oldest type of electronic targets, and uses the Mach wave of the bullet to determine its position as it passes through the target. The first sound-chamber system for big bore rifles was patented in 1975, and was used for the first time in a world championship in 1982.
