Ratings and reviews

I have no doubt that the ability to run a chronograph during our matches has increased my hit ratio. It will also ensure that you don't chase (making a correction) when a round runs slower or faster than normal. if you correct off the slow round and then run normal speed on the correction you just missed again because you were to high. I have the original version and it misses between 3 and 5 rounds per 100 the newer version misses 1 or less out of 100. Very good product

A major flaw in this application and device is that if you close the application, intentionally or by accident, when you re- open the application, it will not Connect again unless you get up, go to the device, turn it off and then back on again. Then use Connect again. All time lost in a competition and just infuriating if not. Please fix.

50/50= Works half the time,Picks up 1/2 the time, Reads out half the real velocity.Longshot Target Cameras is where I bought it. They are kind,courteous and helpful.They can't help this chrono doesn't meet expectations.If a new one does not come out soon I will be buying the new Garmin Chrono..This review above was on Gen1. The Gen 2 version is a Lot better. My partner has Gen 3 and it's even better. Rep. Klara Kozak fixed me and my partner up. I like my Gen 2. It has not missed a shot.
