Steinert SuperChrono + Case
(Acoustic Chronograph)

The Steinert SuperChrono is not dependent on available light. It is an acoustic instrument and will measure any supersonic projectile. It can be used for rifles, handguns and shotguns, provided the speed exceeds 1150fps at sea level.

SOME ADVANTAGES
1. The reading area that one shoots through, on the Steinert SuperChrono, is more than 5 times bigger than the usual optical chronographs.

2. The Steinert SuperChrono is easy to set up and far less prone to interference by wind.

3. The Steinert SuperChrono is not dependent on the available light. It can be used indoors, outdoors and even in moonlight.

4. The Steinert SuperChrono does not attach to the firearm and cannot change the point of impact in any way.
Determining BC is easy with the SuperChrono, where it is impossible with some machines and risky with others.

5. The Steinert SuperChrono is easy to use. It is important to set it up parallel to the bullet path, otherwise the chrono will give either a higher or lower reading than actual. Take care with this, aim it, shoot over it and read it.

How the SuperChrono Works

The SuperChrono is a shooting chronograph that detects the shockwave of a supersonic bullet (1150fps and higher). 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 this figure, 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.

Set up in seconds and measure bullet speeds at any distance

Built-in sight lines and - front and rear sights - make it easy to set up the SuperChrono for bullet speed readings at muzzle level, downrange and at target.

The link given here, is a video about the correct ways you can follow, so that you do set the SuperChrono up parallel to the bullet path. This is of the utmost importance to the SuperChrono in order to measure your bullet speeds 100% correct.

SuperChrono set up procedures.


Convincing test at the National Proof House in Italy.

The national proofhouse at Gardone, Brescia employs a STAS IRBA to test bullet velocities.
This is a state of the art chronograph that comes at a price of pound Sterling 30,000 ($40,500).
On October 28th, 2013 it was used to test the precision of the SuperChrono along with two PVM 21/BMC 18 from Kurtzzeit. These chronographs are priced at pound Sterling 760 in Europe and $750 in the US.

Below are the data from the test shooting:



National Proof House in Italy.


As you can see, the SuperChrono readings are on the average just 0.3% from the STAS's.
The PVMs show a slightly higher deviation than the SuperChrono. Where the SuperChrono has a deviation of 7.4 ft/s below the average of the STAS, the PVMs are respectively 13.6 and 10.5 ft/s above.

The SuperChrono has a higher precision than the PVM 21. A great bargain, considering it cost only half as much. The STAS costs almost 100 times more than the SuperChrono and the difference in speed readings is only 0.3%!

This proves again the validity of the acoustic principle used in the Steinert SuperChrono and tallies with the convincing test in the German weapons magazine Visier.


Just as a matter of interest, the following two photos give you an idea of what the supersonic shock waves look like in reality.

A bullet traveling through air at about 1.5 times the speed of sound can be seen in this image. When a moving object breaks the sound barrier, a shock wave and often turbulence are created. In this image, the curved line at the nose of the bullet is a shock wave. Other shock waves can be seen alongside the bullet, and a turbulent wake trails behind it.

The Mini-Tripod's design makes it possible to be used perfectly with the Steinert SuperChrono, since it's height allows you to shoot easily and safely over the SuperChrono.
Furthermore, the Mini-Tripod is specifically designed to be used on rough and uneven surfaces, thereby allowing users to still have a firm, steady platform required by the Steinert SuperChrono.

Absolutely steady for use with the Steinert SuperChrono, especially when larger caliber's are used on the range to get accurate velocity readings from your chronograph.

Durable, stylish protective case in which the SuperChrono acoustic shooting chronograph, fits very snugly. A separate, zippered compartment holds spare batteries and allen key.


Due to a question asked by one of our customers recently, re the country of origin of the Steinert SuperChrono, we think it is neccessary for our customers to be fully and correctly informed re the exact origin of the SuperChrono and other Steinert products.

The Steinert SuperChrono acoustic chronograph was designed by Swedes and Steinert Sensing Systems personnel - an outright European design and developed product.

Manufacturing is done in China in a factory owned and managed by a Swiss company, where electronic production is done by using German and American machines, on behalf of Steinert Sensing Systems, purely to keep the total cost of the assembled unit as low as possible.
As stated by Steinert themselves: "European production would have tripled the price" of the SuperChrono.

The Neopod light weight bi-pod from Steinert Sensing Systems, is again manufactured in Taiwan - more expensive though, "but they are the high tech gurus of the world", as Steinert's Managing Director puts it.

Maklike aanwending en gebruik van M98 -

Wend jy M98 net so skoon aan met die wol mop?

"Ek het een mop vir olie en 'n ander vir M98.
Die M98 een was ek onder die kraan skoon na gebruik.
Ek vat die droë mop, maak hom aan sy voorpunt nat met M98, stoot hom deur die loop van die kamer se kant af en, wanneer hy so halfmas uitsteek by die tromp, maak ek die voorpunt weer nat met M98 en trek hom terug terwyl ek die geweer se loop skuins na bo hou.
Dan drink ek 'n koppie tee en stoot hom deur met 'n nat lappie. Ek skiet selde meer as 20 of 30 skote op 'n slag en selfs met my 'hotrod' 224 is dit gewoonlik genoeg." ~ Gerard Schultz, GS Custom, samesteller en vervaardiger van M98.

N/B Brushes fit onto Parker Hale cleaning rod thread. WHY do I need a Nylon Bristle Brush (N/B Brush)?

When doing load development it is essential to run a dry nylon brush through the barrel after each 3 shot group. The N/B Brush gently removes all the powder residue from the barrel so that your next 3 shot group can be fired without any interference caused by a build up of unwanted material in the barrel.
More accurate loads are developed by doing it this way.
Run a dry N/B Brush through the barrel before you apply M98 bore cleaner. In doing it this way you allow the M98 to fully clean the barrel and remove all copper, brass, bronze and nitro fouling effectively.
