Davie you are correct in your observation that ETS is probably the most significant advance in our sport in many years.I recollect ferociously arguments over the efficiency of antique timing clocks,I have seen exhausted pigeons picked up and carried towards lofts to be timed in, I have heard of guys going about with T3 clocks strapped to their body chasing tired doos to time them in,I haves seen pigeons so traumatised by rough handling that they refuse to trap.Ifa bird is home it's home it is as simple as that no matter where the ETS pad is.And by the way if you have not used your Unikon system for 8 years it's gonnae need batteries.
