About this deal

The inherent robustness doesn’t translate into bulk; with an overall weight just shy of 1kg, and vital statistics of 210 x 105 x 100mm, it’s easily portable to take to the range, and doesn’t take up much room on the workbench, either.

Un diseño de herradura abierta lo cual nos permite usarlo con armas de aire, armas de fuego, arcos y ballestas. 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. Let’s start with the construction; fabricated from 1.2mm steel, coated with a textured paint that brings to mind cameras from the 1960s, or indeed the dashboard of a classic MG sports car. In one word, probably best summed up as ‘robust’ with the overall im==ression that providing you don’t shoot it, it’s something that’s going to be with you for the long haul.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.

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.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. With four buttons, the Skan is simple and intuitive to operate. You can enter the weight of the pellets you are using, and the unit will not only provide a reading in fps, but it will provide an energy reading in ft-lb.

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. 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. 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. 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.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.

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? El sistema de alimentación también ha resultado una absoluta comodidad, utiliza dos pilas AA que pueden ser alkalinas o recargables.


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.) We are going to mention some very frequent uses but there are undoubtedly many others that right now we cannot even imagine. 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.
