To put it in simple terms the legal limit for a non FAC air rifle is 12ft / lbs of energy ( your old meteor would have produced 9-10), if your rifle is producing over the 12ft / lb limit then you are breaking the law and face prosecution if found out. Well you can still buy meteors and dianas so not everything has changed. Gone are the days when a BSA Meteor or Diana with open sights did for a few rats and starlings in my boyhood it seems. Please call our shop for more information on +64 3 379-8888 in Christchurch, New Zealand.I stumbled into this thread and I have to admit that although it is fascinating reading absolutely none of it makes any sense to me as a non air rifle shooter. We have the largest range of guns, ammo & accessories available now, online in New Zealand. We have been selling, importing, exporting, manufacturing, customising and repairing firearms & accessories since 1978. Gun City is NZ's largest firearms dealer. Set legal limit if required, e.g., UK limit for rifles is 12.0 ft-lbs.Imperial or Metric - Choose mode for speeds in feet per second, weights in grains and power in foot pounds or Metric for meters per second, weights in grams and power in Joules.Pellet weight: As power depends on weight the chronoscope needs to know the weight in grains of the pellet.You can change the display to show in turn the average, the minimum and finally the maximum of the value selected.Īccurate to within 1% but can be fine tuned to match another chronoscope If the power is below the power set as the legal limit the display shows LEGAL. The cb625 remembers which you selected last and returns to that display after a new shot is fired. Press the FPS button for speed and PDS button for power. It then uses the pellet weight to calculate the actual power and then displays one of them. The second sensor sees the pellet and calculates the velocity in feet or meters per second. The counts are made at four millionth a second as the pellet travels the 2.346 inches. Once a pellet has been detected by the first sensor the cb625 starts its timer going and waits for the second sensor to report. Takes LR44 button batteries, mass market product that can be had cheap from many online battery sellers. We highly recommend buying extra batteries as we cannot guarantee how long they will last. The unit comes with batteries (standard button watch type) but these are used for by Combro to test the unit.
