Chronograph ballistics R2H LMBR The perfect chronograph for all projectile speeds. The particularly high-quality product, made from metal with ultra-precise sensors, and works with 1.5 volt batteries. Further, You only need to enter the weight of the projectile, which is recorded in the same, and you can shoot through the window. Furthermore, A direct calculation of the projectile’s velocity as well as its energy will be displayed on the device. In addition to firearms (rifles and pistols), pneumatic weapons (rifles and pistols) and bows, as an illustration the R2H ballistic chronograph model is also recommended.

Firstly, The measurements: air rifles, firearms and archery. Secondly, Firearms_sights_coordination. Lastly, There are two types of system units: metric and imperial.

  • measurement error: <= 1% @ 1000m/s
  • current consumption: 100 mA
  • power supply: 2AA (alkaline or rechargable battery)
  • dimensions R2A ( h x w x d ) 210x105x100 mm
  • dimensions R2H ( h x w x d ) 260x105x100
  • Velocity as V [m/s] and [f/s]
  • Amount of kinetic energy E [J], E [ft/lb]
  • Calculation of shot
  • In IPSC, the power factor is PF (Power factor).
  • In terms of kinetic energy
  • Vavg is the average velocity
  • minimum velocity Vmin
  • maximum velocity Vmax
  • absolute velocity dV=|Vmax-Vmin|
  • standard deviation SV
  • rate of fire RoF
  • bullet weight 0.01 – 50.00 g ( 600 gr )
  • calibration ( settable distance between sensors )
  • memory 250 measurements for velocities
  • data transmision to computer
