Chronograph for Shooting Buyer’s Guide
If you don’t know much about shooting chronographs, then you may not know why muzzle velocity is so important. Heavy bullets that travel at slower speeds will start to fall to the ground sooner compared to a lighter bullet that travels at faster speeds at the same target. A chronograph for shooting can measure this type of difference. For many beginners, a shooting chrony is something they don’t consider using, mainly because these devices seem intimidating to use. But if you want to improve your shooting skills, this type of diagnostic tool can be invaluable. Below, I’ll start this buyer’s guide off by going over how these devices work and the different types available.
How a Shooting Chronograph Works
While a shooting chrony may seem complicated, these devices are pretty simple to use. Once you switch on the device, it will start up a crystal oscillator. The oscillator works sort of like a stopwatch and will turn off and on when rounds pass over the photoelectric cells.
When you fire a round, it creates a shadow when it passes over the first photoelectric cell. The change in light makes the oscillator stop. Since the device knows the exact distance between the cells and how fast a round covered this surface, it’s able to calculate the speed of a round.
Types of Shooting Chronographs
You’ll come across a few standard types of chronographs. Each unit has the same goal of measuring the rate of a projectile, but each type will rely on different types of technologies to get an accurate reading.
A chronograph looks at the light below or above a couple of sensors that are set ten to twelve inches apart. The device waits for the light to be disturbed on each sensor, then it calculates the rate.
Other types of chronographs will work using a similar method, but instead of using a light, the unit is equipped with small electromagnetic sensors. A projectile will disturb the electromagnetic field, then it will calculate the rate and provide a result.
A shooting chrony that uses doppler radar technology is all the buzz in the shooting community. But are these radar shooting chronographs better than light or electromagnetic models, or is it all just hype? If you’re shopping online for a new device, you may have stumbled across an article or two that discusses radar chronology technology and use.
Labradar is one of the leading manufacturers in the industry. Its release of the Labradar doppler radar chronograph comes with a steep price, but some gun enthusiasts claim this model is well worth the money.
When not equipped with artificial illumination, optical models can run into issues with accuracy. Too little light or too much light can produce system errors or missed shots. The use of electromagnetic sensors are meant to solve these inaccuracy issues, and while they can help, these tools are not without their limitations. Labradar chronographs don’t use the same type of doppler radars that the military uses because products that are sold for civilian use must meet FCC regulations. These regulations limit transmissions, which impacts the device’s radar range and sensitivity. However, Labradar’s shooting chronograph is sensitive enough to capture bullet velocity, with the help of an acoustic mic.
Labradar Offers an Alternative to Older Tech
Unlike other technologies, the Labradar shooting chronograph doesn’t capture the velocity by determining the amount of time it takes a bullet to shoot between the start and stop sensors that are separated by a fixed distance. Instead, the acoustic mic is used to establish the start and stop time of each shot, then it calculates the velocity backward to the muzzle from doppler returns that are reflected off the bullet’s base. During this time, the radar constantly pulses so that reflections are kept at random ranges for every shot with a range of 15 to 25 feet. Chronographs that use doppler radar technology do not measure velocity between sensors. Instead, a reading is processed using firmware that predicts the muzzle velocity. Of course, the right electromagnetic or light system can offer the type of accurate readings all shooters are looking for, without the steep price that comes with a doppler radar style system.
Which Type of Chrony is Right for You?
The word is still out concerning how reliable the chronograph radar systems are, and they also come with their own slew of problems, such as issues with standard deviation, high power needs, and difficulty aiming the shooting chronograph precisely down range to get an accurate reading. For now, most shooters still prefer the standard electromagnetic and light chronys that have been around for decades, due to their ease of use, lower price tag, and reliability.
Before you order one of these devices, there are some important factors you should consider. These factors will determine how reliable, accurate, and easy to use a device is, and whether or not it’s compatible with your firearm.
When you’re shopping for a shooting chronograph, accuracy is by far the most important factor to consider. The ability to find a bullet’s true velocity is heavily dependent on how accurate a device is.
Fortunately, most models are calibrated right out of the box. However, it’s important to be aware that accuracy can vary from model to model. In terms of accuracy variation, it’s usually only a one to two percent difference. Although, when it comes to any type of measuring tool, this can be a major difference.
If you want to learn just how accurate one of these devices is, make sure you read shooting chronograph reviews, where you can read reviews from real customers who have experience with each particular model you’re interested in.
On most devices, you’ll find a display that lists important data and statistics. A large LCD display allows you to easily review your data in bright and low light conditions. However, you may also come across a low quality display that is difficult to read in bright light. Many of the leading models come equipped with an LCD display that can easily be read in a variety of light conditions, whether you’re indoors or outside. Steer clear of any device that received low marks for display quality or design.
Typically, the display can easily be controlled with the use of 1-2 buttons that are used to scroll through the stored data.
Ease of Use
Generally speaking, a shooting chronograph is pretty easy to set up and doesn’t require much in terms of assembly, aside from putting some sun shields and rods together. Additionally, a shooting chronograph is usually calibrated at the factory, so it’s ready to use right out of the box. If the device comes with a large display, you can reference the user’s manual to learn how to retrieve and save important data. Many modern systems now come with a dedicated app that will display all of the data from past shot strings instantly and store them for later review.
Unfortunately, some apps are more intuitive than others, so you may find yourself struggling to navigate the user’s menu on your phone to access certain features. These problems usually come from newer apps that still have some bugs that need to be worked out.
Read the User’s Manual
Before you try your chronograph for the first time, make sure you read every page of the user’s manual, and an online article or two regarding your specific model. You can also watch Youtube videos, which can be very helpful, especially if you’re a new shooter and have never used a chronograph before.
What Can Impact Chronograph Readings?
Below is a list of factors that can have a negative impact on a chrongraph’s readings.
A bullet’s powder will burn slower when it’s cold out. Because of this, it’s normal for a shooting chronograph to record lower velocities than it will when it’s hotter outside or once the ammo and barrel have had a chance to heat up.
If you’re using a chronograph with light sensors, be sure to check that both sensors are receiving the same amount of light. Don’t expose the sensors to direct sunlight on bright days.
One of the biggest issues that can impact accuracy is muzzle blast. Muzzle blast can interfere with the chronograph’s results if it reaches the sensors before a shot. Because of this, it’s important to keep the device about ten to twelve feet away from the muzzle.
Data a Chronograph Can Provide
The best shooting chronographs can provide shooters with important data, including extreme spread, shot string data and shot speeds.
All of these devices will provide data on speed. Most models will display this info in meters per second or feet per second, so you can choose how you want to display the data, based on personal preference.
Most of these devices can keep track of a string of shots. This provides important info regarding a user’s shooting skills, which makes this tool just the thing some shooters need, if they’re looking for a device that’s accurate and one that can help them advance their shooting skills.
Highest & Lowest Velocity
The highest data shows the user the value of the fastest shot in a string, while the
lowest data provides the value of the slowest in a string.
Average velocity is the average speed of all the shots combined
Not all models are able to measure the power factor, however, some can. This type of data will multiply a shot’s velocity with a bullet’s grain to calculate the power of shots.
Extreme spread info shows the difference between the slowest and fastest round.
The best way to find value for standard deviation is to fire a minimum of ten shots per string. Fewer shots in a string can make the data unreliable, so, if you want a better value, then be prepared to shoot more rounds.
The power factor is the ranking system that’s used in shooting competitions. The power factor measures a round’s momentum and will scale it to its weight. This data is calculated in Newton seconds and is what determines a shooter’s score.
Setting Up a Chronograph
When you’re using a shooting chrony, there are some basic rules you should follow.
You’re not supposed to shoot at one of these devices. This may seem obvious, however, it also happens to be the most common mistake those new to chronograph use have made. You must shoot over the photoelectric cells if you want an accurate reading.
The chronograph’s reading will be more accurate if you’re able to fire consistently over the same spot of the photoelectric cells. For this, scopes, boresights, and red dot sights can be really helpful.
Shots should pass over the light sensors at a minimum of five inches above them. If shots pass higher, the device may not detect it.
If you end up using a red dot sight or a scope, don’t set up the chronograph based on their height. A red dot sight or scope is often positioned a couple of inches above the bore.
Read the chronograph’s instructions and follow them closely. If the instructions don’t mention how far you should stay away from the device when you take shots, make sure you place it a minimum of ten feet away from the muzzle.
- When you plan on using a chronograph, take several guns with you. If you’re using a high power rifle, make sure you give the barrel time to cool down, otherwise, the chronograph may provide inaccurate information.
- To prevent false readings, be sure to set the chronograph at the correct distance.
- Set a target at the same distance as the chronograph, shooting once from each firearm to determine the point of impact at the set distance.
- Before you shoot over the chronograph use the target to determine where to aim over the device. Shots should not be placed closer than two feet or more than four feet above it. Keep in mind, sky screens are not sensors. The sensors can be found on the top edge of the device’s body.
- Keep a notepad on hand to write down the results, noting the type of firearm and load used. You can write down other information, including the temperature, light conditions, and any other information that can impact readings.
- Keep extra batteries on hand. Chronographs tend to die at the most inconvenient times.
- Be sure to mount the chronograph on a sturdy stand or tripod that will keep it securely in place.
- Take shots from a bench rest position. It will be a lot easier to make shots from an off hand position and hit the chronograph. Be sure that the firearm doesn’t touch any part of the rest or bench since recoil can cause the muzzle to jump.
Do I Need a Shooting Chronograph?
A shooting chrony may be useless to the average shooter, but if you shoot competitively or you want to learn how to shoot long range with precision, then using one of these devices will be the best thing to boost your shooting performance. Precision long range shooting is very velocity dependent. While chronographs are considered devices that are more directed toward advanced shooters, they’re actually easier to use than most people think.
