Introducing the MagnetoSpeed V1 & V2 Chronographs

A revolutionary barrel mounted ballistic chronograph technology with patent pending magnetic sensor technology. Highly accurate, portable and easy to use. Works with your rifle, handgun or shotgun.



All shooting chronographs currently marketed to the general public use optical sensors.  The MagnetoSpeed uses electromagnetic sensors (patent pending) to detect the presence of the bullet.  These sensors are immune to muzzle blast, which allows the sensors to be located near the muzzle.  As an added benefit, these sensors are immune to common light problems such as fluorescent lights, low sun, bright sun, etc.



Our unique method determines velocity by sensing the difference in time between a slight disturbance in two magnetic fields as the bullet passes by.  This is somewhat similar to the way that an electric guitar senses the vibration of its strings to produce amplified tones.

Magnetospeed custom prototype testing at the Southwest Research Institute.



MagnetoSpeed LLC worked with Southwest Research Institute(SwRI) to quantify the ballistic accuracy of the MagnetoSpeed sensor package.  SwRI uses a bench top range setup to do ballistic tests on ammunition and uses a double Oehler sky screen setup to accurately capture bullet velocity.  In the table above, seven shots were taken all using the same  ammunition (7.62x51mm M80) with the MagnetoSpeed sensor as well as the double skyscreen Oehler setup.  Velocity 1 above is the velocity measured at the first set of skyscreens and Velocity 2 is read at the second set.  When the muzzle velocity is back calculated based on the distance between skyscreen sets and the muzzle we obtain the "Calculated Muzzle" velocity in feet per second (fps).  Comparing this to the Magnetospeed data we get percent differences of less than half a percent.  This data series shows that the MagnetoSpeed is at least 99.6% accurate to the Oehler system used at SwRI for this test.
