CMP Readies Electronic Target System for Oklahoma CMP Games
Report by Johnny Fisher
The Civilian Marksmanship Program has just finished temporary installation of 15 traveling electronic Kongsberg Targets at the Oklahoma City Gun Club in Arcadia, OK. These high-tech targets will be employed during the Oklahoma CMP Games, slated for April 6-10, 2016. All the High Power rifle events during this year’s Oklahoma Games will be run exclusively on these electronic targets. Competitors will be scored electronically with match results being processed in real-time. Notably, this means High Power competitors will not have to do “pit duty” the entire week since manual target-pulling and shot-marking is no longer required.
The majority of shooting at the Oklahoma CMP Games will be fired at the 200-yard line for the Garand / Springfield / Vintage & Modern Military (GSMM) matches. However, the electronic targets have also been readied for use in the scheduled Excellence In Competition (EIC) and Vintage Sniper matches. Those events require additional firing from 300 yards and 600 yards.
Electronic Target Technology — How Kongsberg Targets Work
CMP Targets technician Bryan Parris explains what makes these targets so special: “These targets were designed by the experts at Kongsberg Targets exclusively for the CMP to fit the standard US target dimensions of 72″ square target backers. What shooters discern as the black of the aiming bull is actually black rubber sheeting that is the entire size of the backer. A layer of white corrugated plastic then covers this rubber with a center hole having been cut out to reveal the appropriate sized bull for that yard-line. All that is required as competitors move further back through the course is to change out the plastic cover to reveal a larger aiming black.”
This acoustically-scored target system uses four microphones to locate the bullet as it passes through the target. The microphone closest to the bullet traveling through the target actuates the remaining three to triangulate the exact shot location for the scoring system and simultaneously display the shot on the shooter’s monitor.
Behind the coroplast face and inside the foam insulation, the target is wrapped with rubber to form a type of chamber. This helps insulate the target’s four microphones stay insulated from extreme temperature changes and also helps keep out ambient noise. This chamber need only exist to the extent that it separates itself from the other targets. Parris states: “We’re building these targets to last a great long while. They are extremely durable and can have anywhere from 3000 to 5000 rounds fired through them before any maintenance is required whatsoever.”
The entire system can be powered via battery, generator, or combination of both. The target line communicates wirelessly with the firing line computer system for timing courses of fire and recording scores. And of course, there is virtual real-time communication with monitors set up on each firing point to display shot / group location and value.
When fully assembled, each target weighs about 200 pounds. They are a little cumbersome in their current form, but the CMP’s target technicians are “still working some things out [for] potential future travel games.”
Registration Still Open for Oklahoma CMP Games
The 2016 CMP Oklahoma Games will be held at the Oklahoma City Gun Club in Arcadia, OK from April 6 – 10, 2016. Registration is still available. For more information about these Kongsberg Electronic Targets, contact Bryan Parris of CMP Targets at (256) 835-8455 or bparris@thecmp.org.

Just wondering, if a shooter sights in his rifle at one firing point will that zero hold true on all firing points. I don’t see how the acoustic senors on each target could be exactly the same on all firing points.
Yes – the acoustic sensors would have to be calibrated after the target is assembled. Most likely there is some kind of “wand” that makes a clicking sound, and they poke it right in the center of the x-ring. Once the sensors are calibrated to the target face, they will tell you the real shot position on each target. Kongsberg has been using this kind of technology since the 70s for underwater survey – it’s called long baseline or LBL.
What is that acoustic senor? Can we buy that senor?
