I often wondered why so many were against ETS, myself included, but now I have seen it in use and now my club has them I would'nt be without it, its a lot easier for marking and taking off also doing the birds good not getting caught everytime they drop in from a race, you know when all your birds arrive and what ones are still to com, you get a printout of your birds after basketting, and a printout of our birds timed and now with the velocities on each bird, yes its great,
