What is the difference between the MagnetoSpeed Sporter and V3?
The main difference is that the Sporter can fit on barrels from . 5″ to 1″ in diameter. The V3 can fit on barrels and suppressors from . 5″ to 2″ in diameter.
How does a MagnetoSpeed work?
MagnetoSpeed’s barrel-mounted ballistic chronographs use patented electromagnetic sensors that are designed to operate in the harsh environment at the muzzle of firearms. Using the provided spacers, the shooter adjusts the bayonet so that the bullet will travel just above unit’s sensors.
How accurate is Magneto speed?
What is the accuracy of the MagnetoSpeed Chronograph? The accuracy of our chronographs can be expected to be between 99.5% and 99.9%.
How does a speed chronograph work?
The modern chronograph consists of two sensing areas called chronograph screens, which contain optical sensors that detect the passage of the bullet. The bullet is fired so it passes through both screens, and the time it takes the bullet to travel the distance between the screens is measured electronically.
Does Magnetospeed affect group size?
Any time you change the weight at the end of a barrel it can affect both poi and group size. My experience with the Magneto speed is mostly with carbon barrels and the group size is affected very little if any.
What is a tachymeter bezel?
A tachymeter bezel is used to calculate speed or, in other words, measure elapsed time over a fixed distance. As daunting as the bezel looks, it’s incredibly easy—and surprisingly intuitive—to read a tachymeter scale rating. To use a tachymeter bezel, press the chronograph pusher to start the stopwatch.
How far does a chronograph go?
You need to be far enough away that the muzzle blast doesn’t affect the screens; the gas exiting the muzzle is faster than the bullet and can cause false readings if it reaches the screens. With rifles and the higher pressures they run, you need to be further away – 15′ is usual.
How do you use a tachymeter bezel?
To use a tachymeter bezel, press the chronograph pusher to start the stopwatch. Once the object (for instance, a car driving one mile) passes the finish line, press the pusher again to stop the stopwatch. Then reference the tachymeter scale marker adjacent to the second hand; this figure tells you the speed of the car.
What is a chronograph for use with ammunition?
In a nutshell, a chronograph lets you measure the speed that the bullet leaves the barrel. The speed the bullet leaves the barrel, often expressed in FPS (feet per second) or MPS (meters per second) is known as it’s velocity. This is often given to you on the outside of factory bought ammunition.
What a tachymeter is used for?
The most common use of a tachymeter is for measuring the approximate speed of a vehicle over a known distance. e.g.) Based on how many seconds it takes a vehicle to travel 1km or 1 mile (the available measuring range is up to 60 seconds), the average speed within the distance can be calculated.
