I think it's got to be the future there is so much information we could find out for training it would be great, play about with places you go see where the birds are heading bop hot spots, I'm really surprised no one has tried I get the price is expensive but there are cheaper alternatives I've heard of others that work but u strap on to a pigeon not round leg that weigh about 6 grams, skyleader seems the way forward all there videos are really impressive and u can get a set up for 300 dollars,I've got on at them bout not Europe vendors and in till they have some I'm not going to buy, the guys in Norway seem to have a good set up that's coming up for 100 pound but not available till next year,all it takes is one club to try it I hope in the future we do
