I just recently bought a SuperChorno Acoustic Chrongraph. A little spendy but solves a lot of misread problems due to sun, clouds, whatever and does things downrange other chornos can't do. Have not had a chance to use it yet, but impressed with what it claims to do. So much simpler to use without the headaches.The World’s First Acoustic Shooting Chronograph!
After 30 years of optical chronographs, Steinert Sensing Systems finally delivers a new technology that gives you reliable shot speed readings in any lighting conditions.
99% precision or better
The SuperChrono’s supersonic shockwave processing technology offers unsurpassed precision independent of lighting and weather conditions. Every SuperChrono is individually calibrated to give a precision of ±0.5% of measured velocity or better.
No more undetected shots
No more worries about sunlight orientation, uneven cloud cover, shadows, reflections from snow or water on the ground, low or indoor lighting, shiny projectiles, shadows or any other changes in light intensity that can cause problems with optical sensors. The SuperChrono detects shots even with rain or snow on its sensors.
Huge shooting area
As an added bonus, the SuperChrono’s supersonic shockwave processing technology offers an optimum shooting area up to 300 times larger than the tiny 2x2 inch area for optical chronographs. This makes it easy to get velocity readings from close to the muzzle to any downrange distance as long as the bullet is supersonic.For the first time it’s easy to get downrange velocity readings and to calculate exact ballistic coefficient.
It has never been easier to get total control over bullet trajectory!
Set up in seconds and measure bullet speeds at any distance
Built-in sight lines, front and rear sights and a spirit level make it easy to set up the SuperChrono for bullet speed readings at muzzle level, downrange and at target.
Easy to use as a diagnostic tool
Use the SuperChrono to check for variations in bullet speeds if you find an odd flyer in your shot group or if the groups are not as tight as expected.
Works with any calibre
It doesn’t matter if it’s a tiny .17 HMR or a rocket; if it’s supersonic, the SuperChrono gives an accurate reading of its velocity.
No menus. No loose parts
The SuperChrono is simplicity itself. No menus to learn and no loose parts to mislay.
How the SuperChrono Works
The SuperChrono is a shooting chronograph that detects the shockwave of a supersonic bullet. A subsonic bullet does not generate a shockwave and so would not be detected by this product.
We use ultrasound microphones to detect the bullet's shockwaves. As you can see from the last picture, the shockwave first hits sensor one at T1 and then hits sensor two at T2.
The SuperChrono's incredibly fast electronics sample the sensors 40 million times every second. When T1 and T2 are registered, its microprocessor calculates and displays the velocity of the bullet.
As an example, let us say the difference between the readings at each sensor is 0.00025 seconds, while the distance between the two sensors is 200 millimetres. The time it takes the bullet to travel one metre is therefore 0.00025 x 1000/200 = 0.00125 seconds. This gives a bullet speed of 1/0.00125 = 800 metres per second or 2625 ft/s.
