What Targets Does FreeETarget Support?
Who Uses FreeETarget?
FreeETarget is used world wide on all of the continents except Antartica. FreeETarget is designed as a low cost electronic target for training use. Some of the users are:
- Olympic athletes
- National teams
- Junior Olympic trainees
- Anyone who wants to shoot more and better
How Does FreeETarget Work?
freETarget has four microphones placed just behind the target. Located at the 2, 4, 8, 10 oclock positions, they listen for the sound of the target paper tears. As the projectile goes through the paper, a counter is started, and using the time difference between the microphones the firmware figures out the location of the hit.
The projectile location is transmitted to a PC which puts the score on the display and keeps track of your score.
What are the Design Goals?
We wanted freETarget to be accessible to a wide variety of users regardless of where they live in the world.
- Low cost parts
- No export barriers on components
- Limited technical expertise
- Use indoors or out
- Easy to assemble on site
- Support both pistol and rifle use
Putting all of this together, freETarget uses a PC laptop as the display device, and connects to the acquisition hardware using a long USB cable or WiFi.
How Accurate is FreeETarget?
The accuracy is a function of how precisely assembled the target holder is. Another source of accuracy is the management of the witness paper. With a bit of care, the average error is in the order of 0.2mm per shot or about 0.1 points on an air rifle target.
What Targets Does FreeETarget Support?
freETarget supports all of the ISSF targets from 10 meter airgun up to 300 meter guns. The initial design was for 10 meter events, but by changing the target size and backing material, rimfire and centerfire cartridges will work.
Special national targets are supported. New targets can be added as needed.
Some work is being done for F-Class at 1000 meters, but the results are not yet in.
How Do I Make FreETarget?
There are three ways you can build freETarget
- Visit Github.com/ten-point-nine/freETarget for the complete design files
- Buy the circuit and assemble it into your own target housing
- Buy one of the complete kits and assemble it yourself
Can I Buy the Parts?
Yes, the circuit is available for purchase at $230 US plus postage. Visit the Store page to setup purchase and shipping. https://free-e-target.com/store
Many of the builders have made 3D printed parts available. Look up the 3D parts at Community Made Parts
Will You Take it Back?
No
freETarget is a community based open source project that relies on the user’s to make it work. This is not a commercial product that you can call customer support for. Ask somebody in your club for technical help, there’s bound to be a computer nerd who can help.
