I love my crony, it's an irreplacable tool for guns - Shooting Chrony F-1 9 Volt Chronograph

My one and only complaint is I get a lot of errors which can be a real drag sometimes. For example if I'm working up a load and have five loads to test it has sometimes given 4-5 failures in a row so I have to go home, load more and back to the range. Very frustrating! I found a solution by using two Crony's, chances of both giving an error are rare. Other than that I love them, they're an invaluable tool.
Pros: It does what it says and thank god Crony's exist
Cons: I get a lot of errors
