Chronograph

I have these two items. I use them for archery and air guns. I've been using it for archery for 7-8 years with ZERO issues. It is lots of fun to tinker.

The Bluetooth attachment is AMAZING! It is a wireless connection for my iPhone. You need the light kit for the Pro Chronograph.

I would also check out the brand new chronograph by Caldwell.

I have had a Shooting Chrony Gamma model with printer for over 10 years and it has been great. I got it mainly for powder burners but it works well for air guns and arrows as well. I occasionally think about getting an Oehler 35P but cannot justify since the Chrony is so reliable. I originally had the basic Chrony F1 low end model which worked fine but I upgraded to the Gamma with printer since the company has a pretty fair trade in policy. Other chronographs may be good as well but my experience with the Shooting Chrony has been really good. I'd buy another if mine broke.
 
"ajshoots" I prefer the Competition Electronics Pro Chrono with IR screens. Has been by far the most reliable and with the IR screens, I have had absolutely zero errors!! I have used other products made by CE and they are a great company in all regards and make a great product.



Okay I can't find any reference on the CE Pro Chrono site that speaks of "IR Screens" . Could you put up a link. I have the Pro Chono and it is quite light picky. The diffusers are useless unless the light is directly above. It does work though under the right conditions. I shot mine all apart one day, (who hasn't?) they sent me another for 70 something bucks.
 
I have the ProChrono and like it a lot. At first I had issue with it not reading all the time. The problem was the light reading. Since I upgrade to their light system it never misses a shot now. This is the 2nd ProChrono I've had. The first one died a sudden death when a .308 PB round went through it. I made a carrying case that keeps all the parts together. This way it not only protects your chrono, but when you get to the range, you know you have all the parts needed. I like the software that comes with it. Easy to use and good displays.
