This review is from: Shooting Chrony F-1 Chronograph (green) (Sports)
I have used this product for 4 years now and love it. If you reload then you really need to have a chronograph, their are so many variables involved including things like chamber dimensions that vary from gun to gun so the load manuals aren't always accurate. The F-1 has proven to be accurate and durable (I clipped it with a 223 bullet once that peeled back the metal housing a bit and it still works perfectly) especially for the price. I would recommend setting it up on a cheap tripod so you can easily adjust it to the best height and this will make it very easy to level it on rocky or unlevel terrain. One thing I will mention to the folks who get a lot of errors with this unit, make sure to read the manual, sometimes you want the shade screens up, sometimes you dont. Also you will sometimes get errors when shooting subsonic bullets up close to the unit as the muzzle blast will get to the unit sooner or soon after the bullet does. Also take your time setting it up at the distance recommended in the directions and shoot thru it level and 4 inches above the sensor. Keep in mind at close range to account for the sight being X inches above the barrel!
