CHRF1 Chronograph F1, One Size

Excellent piece of equipment and very, very easy to set up and use once you install your own 9v battery. Switch on and the screen is ready for readings from shooting the air or cartridge rifle. As long as printed instructions are followed by shooting through the detectors at a height of 4" minimum clearance from the photo cells and a 5ft distance away from the Chrony to avoid muzzle blast giving false readings, everything works perfect. My airguns are now proved perfectly legal within UK regulations of less than 12ft/lbs energy for air rifles and 6ft/lbs energy for air pistols. Well worth the cost to remain legal. Ignorance is no excuse in law.

Have used this several times and found it reliable but sometimes infuriatingly it fails to read, usually just when you need to know the velocity urgently. Very easy to use.

A "must have" if you intend to do any work on your air rifle, both so you can make sure your work is positive and so you can make sure your Sub 12 ft lb stays UK Legal. Also recommend some jeweller's scales so you can properly weigh a batch of 19 pellets before running them. Only limit with the basic version is you need a good sunny day to get consistent readings, but they're are lamps available if you need to use it indoors.

Having tried a cheaper alternative that failed and had problems then I did what I should have done in the first place and bought a top quality reliable and accurate instrument. This really does work very well and the build quality is 100%.

Arrived very quickly, and having read a few reviews commenting on how difficult it was to set up I was a little apprehensive. My fears however were completely unfounded. the instruction were very clear, and easy to remember, and on the first outing I had it set up and working perfectly in under two minutes without having to refresh my memory

first time my father has used it due to an illness since christmas and the led display keeps showing error. Happy to speak with the seller and remove this review if we can rectify. Kind regards

A must if you like to tinker with your toys. Been putting off buying one for years due to the price but i'm so glad I picked this up. First thing I did was to Chrono my BSA S10 which had just come back from the RFD who serviced the cylinder due to leaks. To my horror it was putting out 17 foot pounds and was promptly returned to the RFD. The rifle did not feel any different to my other rifle which puts out a constant 11.2 foot pounds. So to be on the safe side get yourself one of these to ensure you stay within legal limits , forget the cheap alternatives they are not as good as a Chrony.

the f-1 shooting chrony is easy to set up and use ,its well made and should last me for a very long time it seems to be very accurate and will fold up for easy storage
