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

Product Information

Okay, but how will all of this help me to improve my shooting?’ I hear you ask. Well, it will help in four main areas:

Making use of pellet weight, the LMBR calculates individual power, as well as average if you shoot a string, even if that string extends to 250. All this will be delivered with an accuracy of 1% measured at a velocity of 1,000 M/S. To test the validity, I took a comparison from my benchmark chrono’ - Skan Pro 1, which gave near identical results.When the cover is replaced, be careful that the two slots allow access to the sensors below. It is possible to fit it the wrong way round, which means the sensors are occluded and the device becomes inoperative. 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. 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. Buenos días a todos, tal y como sospechaba creo que ya puedo comunicaros con firmeza una estupenda noticia tras varios meses de trabajo e investigación sobre la pesadilla de los cronógrafos balísticos, y es que…… “YA TENEMOS EL CRONO GANADOR”.

The chronocan displaymetric (m/s) or imperial (fps) readings and it will calculate the power settings based on pelletweight and pelletspeed. It is suitable for arrows, airgun pellets and BB. The LMBR chronograph is the brainchild of Radoslaw Koziol an electronics/ telecommunications engineer based in Bartag, a small village in Poland. His original work started in 2007/08, and in his own words, was more a hobby than anything else. As often happens, matters started to get a bit more serious, and he changed the brief to produce a reliable practical device capable of producing data that would be useful to the shooting community. From my findings, I think he has achieved his brief and then some, but I’m getting ahead of myself. The essential companion for anyone involved with airgun maintenance.The LMBR R2A Chronograph is a speedometer for measuring speed and energy of your airrifle. An absolute must have when you want to set up your airrifle for the best concistency. Crudely put, chronographs measure the time it takes for a pellet fired from a gun to pass between two sensors. To work out the energy output, the feet per second (fps) reading has to be multiplied by itself, then multiplied by the weight in grains of the pellet and divided by 450,240. 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. 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.

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.) Chronograph readings can be very useful in diagnosing faults, particularly when there are instances of inconsistent velocities causing inaccuracies down-range. I hope I’ve given a few good reasons for you to rush out and buy one, which of course, leads to the question of choice because the market is awash with models of various prices.I already have a couple of chronographs that I use regularly – a Skan, and an FX Radar, which are excellent and come highly recommended, although they both have one limitation. Both are difficult to use down-range, particularly if you don’t want to damage them. If recording terminal energy is your bag, like our own Gary Wain, then you need a chronograph, which with care can be used down-range. So, if this is you, and you also want a chronograph that can be used in the workshop, then the LMBR R2A could be your new best friend. FROM POLAND TO YORKSHIREIf when making a series of shots with an airgun the readings are irregular with large jumps in the speed of the projectile, we already have a major problem because the rifle will not group correctly. Different speeds of the projectile, very different, will cause defects in the grouping of the impacts, this denotes a malfunction of the valve / regulator in a PCP rifle or in the spring and compression system of a piston rifle or any other failure related to this and that can occur in pneumatic rifles (friction, dragging, pieces or broken tires etc.) in any case a defect or fault that must be found and fixed so that the constancy of the shots is adequate again. If you take testing your air rifles seriously, you’ll really want to take a look at this chrono which is the last in our list of chronographs for airguns. According to Skan, police forces use a version of the product here to test potentially errant air rifles and pistols. Many airgun manufacturers are customers too. Obtain directly in joules (or in ft / lb - Imperial System) the energy of the projectiles of your pneumatic weapon or firearm (Cal .22 LR or similar), you just have to provide the weight of the projectile to the device, recording it in it by operating the buttons that appear on the front of it. Shoot through the window, the device will inform you of the speed of the projectile and the energy calculated directly in joules or in ft / lb depending on whether we choose the metric system or the imperial system. For example, a ‘chrony’ will determine the sweet spot on your PCP – the fill pressure range where your rifle is most consistent. It will also help you identify potential problems, and for you tinkerers out there, it will validate the effectiveness, or otherwise, of your labours. (Looking for a compressor for airguns – take a look at our list of the best options.)

Shoot through the chronograph window with a distance from the muzzle (for airguns) of about 10/20 cm. and about 40/50 cm in the case of a 22 LR caliber firearm. or similar. The apparatus will give the projectile velocity and energy readings in joules directly. Although it will handle projectiles weighing up to 49.9 grains and 4,000 fps, the Skan is designed purely for air rifles. Don’t be tempted to use it on your powder burners, as it will damage the sensors. A chronograph is a device that is used to read the speed of the projectiles that we launch with any type of weapon, from a humble slingshot to an Express rifle for big game hunting.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). 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 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)
