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

Product Information

A superb chronograph made of high quality materials – no complicated lighting / shields etc. needed. We have an optional storage bag available for the LMBR R2A chrono what protects the measuring sensors against dust and keeps the chrono in mint condition. We are going to mention some very frequent uses but there are undoubtedly many others that right now we cannot even imagine. Q: A lot of airgun shooters at my local club have their own chronograph, which they use when shooting from the bench. Is this an important accessory to have, and what are its uses?

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: 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) Knowing the speed of the projectiles is useful for many things but mainly, in the subject that concerns us, to obtain ballistic information of the projectiles fired.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. 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. If 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.

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.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 bluetooth connector module that can be seen assembled in the main image is not included in the sale price of the chronograph) El equipo no necesita luz, o sea, puede medir disparos en total oscuridad. Se sitúa a poco más de un metro para realizar las mediciones con armas de fuego, (unos cms con las de aire), con lo que lo tenemos perfectamente a mano sin tener que salir al campo de tiro, ni soportar los problemas o imposibilidad de adaptación a distintos tipos de armas como los Magneto speed, los problemas de lectura del Steinert y su display vertical que nos obliga a ir hasta el para comprobar las lecturas, multitud de errores en los ópticos tradicionales, etc. However, if I put the JSBs through the wrong gun, this will drop to 590fps. There is no doubt that a faster pellet will take less wind and have a flatter trajectory, and there can also be a bigger difference between pellets with different head sizes. The other day, my rifle was feeling ‘wrong’, and when I shot it over the chronograph, it was running at 730fps, so I knew that either a seal had failed, or something more catastrophic had happened, and when I took the rifle apart, I found that I had a broken spring. So, having a chrono’ immediately pointed me toward a problem.

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. 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. Antes de continuar quiero deciros que no podemos conocer a día de hoy el resultado a largo plazo de éstas nuevas tecnologías, o dicho de otro modo, la durabilidad de éstos equipos, pero esto es algo que también nos ocurrió con los CHRONY, CALDWELL, MAGNETO SPEED, STEINERT, etc. Lo importante es que en las pruebas a las que fue sometida esta primer unidad que llegó a mis manos, y posiblemente la primera también en ponerse en circulación en nuestro país, los resultados fueron formidables. Podríamos decir que hemos encontrado un producto que cumple con las tres “B” (bueno, bonito y barato). El equipo se presenta en un formato bastante discreto de tamaño, es portable en cualquier bolsa de tiro normal. Se trata de un equipo compacto que hace todo el trabajo tal cual viene, sin cables, sin pantallas difusoras, sin abrazaderas ni agarres, “una maravilla”. Todo su armazón es metálico, se ve robusto y bien hecho además de atractivo en su diseño. Podemos ponerlo directamente sobre una mesa o enroscarlo en un trípode convencional para cámara fotográfica. Posee un display retroiluminado que podemos desactivar si lo deseamos, el cual está muy inteligentemente orientado hacia el tirador, por lo cual observaremos las mediciones directamente.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 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 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. 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.) Of the three screws that appear on the front, above the screen, the one on the left is used to start the program, tighten it, with it we enter the mode of loading the projectile weights. With the other two buttons, indicate the weight of the projectile, one of the buttons raises and the other lowers the weight. Once you have reached the appropriate weight, press the left button again, in this way the weight of the projectile is fixed and the device is ready for 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. 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) 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 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.
