Great software ... very inconsistent results - Caldwell Ballistic Precision Chronograph G2

I tested this with factory amy from a variety of sources. I was using it outdoors in AZ with an absent tend if 86, in overcast, but bright conditions. Distance to china was 10' Tested loads from Federal, Blazer, LAX Ammo, Freedom Munitions, Perfects, Remington & Winchester. The AE45A (Federal American Eagle .45 Auto 230 RN has a published velocity of 870 fps_ As an example, the Caldwell had it between 119 and 1206 fps in a 15-shot string from a 5: Kimber Super Carry Custom. This was the only string (average of 8 rounds per sting), that recorded all of the shots in the string. I tested this with 15 total strings. Some were with 9mm anon as low as 200 fps with this same ammo. In order to get any results on a majority of the shots fired, I had to use the built-in LED's.
I really wanted to love this Chrono ... the hardware is solid, the tripod is even first ate ... the app is great ... the bluetooth works well ... but these were basically ideal conditions, and it provided me absolutely no useful data. Kinda like the car with all of the perfect features, except it isn't actually drivable.
Maybe I got a lemon - these are BRAND new ... but I'm not sold.
