The MagnetoSpeed V3 Chronograph offers widely adaptable mounting options, making it suitable for barrel diameters from 0.5 inches to suppressors of 2.0 inches. This ballistic chronograph is a real workhorse and reliably picks up shots due to its design. It does not depend on light to obtain measurements and instead uses magnetism, thus enabling the user to take readings on cloudy days and even at night unlike so many others. This ability makes it one of the best rifle chronographs available today.
After the velocity of a shot is recorded, Standard Deviation, Average Velocity, Minimum velocity and Maximum velocity are updated in real time. Information for a string of shots can be stored and recalled later. The user has complete control over the memory storage and can keep data for a group as long as they wish.
The MagnetoSpeed V3 Chronograph is configured for standard rifle velocities as supplied but there are user accessible settings for sensitivity making the system compatible with air rifles and shotguns. Setup requires the use of the supplied spacers to adjust the unit to the diameter of the barrel or suppressor. An alignment rod is included and is used to ensure the ‘bayonet’ type sensor is the correct distance below the muzzle. Once the correct number of spacers is determined they can be semi-permanently fixed the the screws provided if desired.
The MagnetoSpeed V3 is powered by either a 9V battery or two CR123 standard photographic batteries. If you do not have experience with the CR123 you should try them. They were originally designed for very sensitive photographic equipment and provide very constant voltage for their entire lifespan. Packaged in a hard case, there is no reason you can’t take this device with you every trip to the range.

I have other chronographs which have to be set up down range and retrieved to get the data. This is very inconvenient as the range has to stop shooting while you go forward. Embarrassing! 👎🏻
I have used a Labradar; no one in my club has managed to set it up and get consistent results, yet.👎🏻
No such problems with the Magnetospeed. I fitted it onto my 2” diameter Wildcat moderator (no shims needed) attached it to my 6.5 Creedmore, Ruger Precision Rifle, connected it to the ‘brain’ module, loaded, aimed, fired and scored a 3 ring first shot at 1000 yards on Bisley’s Stickledown range. I recorded muzzle velocities for 10 rounds and was very happy with the data. I then removed the sensor rail and my groups closed up; so it Does affect the barrel harmonics/accuracy, but not badly. I will use the rail adapter on my Desert Tech when it comes back from proof as it mounts the sensor onto the bottom picatinny rail, thus the free-floating barrel cannot be affected.
The only chronograph I have used that was possibly better (only because it didn’t attach to the weapon) was in a ballistics laboratory testing bullet resistance, but cost £thousands, needed mains power, and was not mobile.
The Magnetospeed V3 is undoubtedly top of the pile and is now my only choice.

1st is with the sensor rail.
2nd is without the sensor rail.
