I have the blue chrony, beta I think. It's annoying to use. I need to buy that thing that allows me to hook it up to my labtop.
I have only so long between shots on the string, annoying when I'm chronying airguns and I have to #### and reload.
when I want to look at my results, it gives a code, then a number, then a code, then a number, etc...etc.. too fast to write them all down. So I have to wait, then run the sequence all over again, looking for the numbers that are important to me.
The display blows goats, in other words, and the two button interface also blows, and the instruction are obfusticate.
Now, I'm in a wheelchair, so running back and forth to check the numbers irritates me alot more than it might irritate you, so your mileage may vary.
