LMBR Chrono R2 Airgun Air Rifle Pistol Chronograph Shooting Imperial/Metric Ft/lbs

Product Information

Having a rifle that is consistent over the chronograph is very important. I know that my TX200HC with weighed pellets will always be within 5fps either side of 775fps. However, over the years I have shot chrono’ strings in the heat and the cold, and I now know that if the ambient temperature is over 75°F, my rifle will slow down, and if it’s below 40°F it will speed up. The R2A chrono is supplied with 2 AA batteries and it is possible to connect the R2A chrono with a external power adapter (optional). Alsocan it be connected to your PC with a USB to RS232 cable (not included) Made in the USA, the ProChrono DLX Chronograph has a velocity range of 20 – 9,999 feet per second, memory capacity of up to 9 strings of up to 99 shots each, and a shot timing resolution of 31 nSec (8000 counts @ 4,000fps). Its crystal controlled accuracy is +/- .5% of measured velocity or better, making it a reliable and accurate tool for measuring the velocity of projectiles in various shooting sports. There really is no excuse for exceeding the legal power limit and that’s where chronographs for airguns are useful kit. Manufacturers go to extraordinary lengths to ensure their products comply, and licensed gunsmiths know that any breach would have serious consequences for their livelihood. (Read our list of the best airgun pellets.) The big advantage of a chrono’ like the LMBR R2a is the ability to place it downrange. The large 120mm aperture means that you can shoot it safely from a distance, and unless you are having a very bad day, you can shoot it safely.

A superb chronograph made of high quality materials – no complicated lighting / shields etc. needed. In rifles or air pistols, chronographs are usually used to find out the constancy of the speed of the projectiles fired in such a way that if the readings are very similar and there are hardly any variations between one and another, that is, between the speed of the projectile one shot and the next, and so on in a series of X shots we can see that the weapon has a good valve or a good regulator or a spring in good condition that makes the projectiles all fly at the same or very similar speed. That is the first step to a good weapon accuracy.The Combro cb-625 mk4 is a competent and effective tool. The unit is designed specifically for airgun use, while claiming (a little confusingly) to handle a maximum of 2,000+ feet per second. We are going to mention some very frequent uses but there are undoubtedly many others that right now we cannot even imagine. Ignorance, it is said, is no defence in law. Responsible airgunners know that without a Firearm Certificate (FAC), possessing a rifle that pushes out more than 12 foot pounds (ft-lb) will not only get you into trouble, but fuel the argument of those who’d like to see our sport disappear. (Read how to get an FAC for your air rifle.) The unit comes with a lead to transfer information via a data port to a computer, and a charging cable which also attaches to a PC. The Shooting Party recommends the Ballistically Brilliant Chronograph be fully charged before use, and says it can handle velocities up to 2,789 fps.

Sus lectores más anchos que los habituales en los equipos ópticos actuales, nos permiten la suficiente imperfección en los ángulos de disparo para que la lectura sea correcta. De hecho se puenteó con un CHRONY y mientras éste daba sus típicos errores de lectura si la luz del cielo cambiaba o el transito del proyectil no era bastante alineado, el nuevo equipo no dio UN SOLO ERROR DE LECTURA durante la semana que se sometió a pruebas intensivas. The Caldwell Chronograph G2 is also designed for powder burners and even bow users, capable of measuring projectiles up to 9,000 feet per second. Presented in a carry bag, the G2 comes with its own tripod, which can be adjusted between 80 and 170mm high. Do not buy imitations of the LMBR brand, they only look alike on the outside, see that the LMBR brand is engraved on the front of the device. Only the original brand guarantees correct operation, meets guarantees and satisfies all the functions offered) El equipo admite previamente ajustes para entregar su máxima precisión, calibración de lectores, así como para indicarle si vamos a usar armas de aire o de fuego. No obstante he de señalar que con el ajuste de fuego, el crono realizó también las mediciones con aire a la perfección. The MagnetoSpeed Sporter chronograph kit is designed for use on barrels from 1/2 inch up to 1 inch in diameter and can accommodate muzzle brakes and flash hiders up to 2.7 inches in length. It is ideal for contoured rifle barrels (sporter barrels).

The use of one pellet or another, with one shape or another and with one weight or another will provide variations in the speed of the projectile. With the chronograph, we can find the pellet that most closely approximates the ideal speed for the caliber we are using for the sake of maximum precision or for any other purpose. We can say that the chronograph is a magnificent tool that provides us with information that we cannot obtain in any other way, without it we are blind, that is the matter. By shooting trough the LMBR R2A chronographthe display shows you the exact pellet speed and power of the rifle. The simple and decent design makes the chronovery easy to use. To start the process, you are going to need to input your pellet weight, which has a maximum available value of 600 grains – imagine the trajectory of that pellet! Once done, shoot down the centre of the open aperture, where you will have a choice of viewing various items of valuable data, available in imperial and metric units. At the very least, you are going to want to see velocity, and this over a series of shots. From a string of shots you can choose to see the maximum, minimum, average, and the difference between maximum and minimum velocities. So, let’s say your .22 rifle gives a reading of 530 fps. With 16 grain pellets, that would be: (530 x 530 x 16) / 450,240 = 9.98 ft-lb. Fortunately, if maths isn’t your thing, plenty of calculators on the internet will do the number-crunching for you. A chronograph is also essential if you plan to tune your airgun by adjusting factors such as regulator pressure and hammer spring tension. The measurements you take will reveal what effect your adjustments are having on the pellet’s velocity and your airgun’s muzzle energy.
