The BFTA has in the past 10 years tried 3 types of chronograph. All with variable results.
It must be considered that we require a chronograph that is easy to use and that it is in constant transit around the country.
After one outing the new chronograph performed very well. On Sunday its batteries failed and if this did lead to erratic reading then it is something learned. I will advise all regions to start the GP with new batteries.
As to the accuracy of the chrono?
Did anyone fail on Saturday or Sunday? There was no one reported as doing so.
As some have said "they do not trust the chrono" - perhaps that's good advice.
It's unfortunate that criticism is easy but decision making is not. The decision to try this chrono was built upon advice and testing from a respected source. However, I and he would know that as soon as purchase is made they'll be a queue of people to say why another model would be better.
