Things I liked:Fills my air rifle as advertised. I found the guage to be accurate to what the manometer on my rifle says. Things I would have changed:i would like both BAR AND Psi readings. This guage only reads in BAR. Not really all that big a deal but would be nice. What others should know:Leaks a bit at high pressure.. can hear it hissing out from where it attaches to the Yolk, just in front of where it attaches to the tank. I expect some teflon tape will cure that. leak is slow and still fills my rifle.
Things I liked:Ease of use; compact- folds up in an easy to carry and store unit; Accurate; gives read-outs of not only fps but in a series: high fps, low fps, average fps, extreme spread and standard deviations; Grate value for the money- I can remember when owning a chronograph was way out of the average persons budget. Thanks Chrony!! Things I would have changed:Nothing. This unit has everything your typical range rat could ever want. What others should know:You must buy the lighting accessory if you plan on using it indoors. While the Chrony itself is a great value, the lamps are quite overpriced for what you get. That being said, the chrony and light package together is still a great value, just a little less so due to the overpriced lamps.
