Getting a tracking collar was a requirement for my old E Setter. Way to much drive and not enough bidability. I've picked him up as far out as a bit over two miles. My other could go without it but I found out hunting grouse with them not only do I know where to look for them but I can follow my own track back out. My little Red Setter doesn't run near that big and I could do him with out it but in heavy cover I get a lot of security from it. Dog's are being bred for more and more independence and range, tracking collar is a good idea.
