I have this chrono on test for Shaun and the BFTA. So if it`s ok it will be the one used at the GP`s this year.
I`ve tested my cannon on it a few times and what I`ve found is that it is very good. The readings are consistent and accurate. I`ve found that you need to shoot the pellet over it around 100mm over the sensors any higher and it wont read or gives odd readings. Plus it dont like being in a wooded area so I suppose it is light sensitive. Overall on Sunday the chrono performed well and nobody failed!
