Life would be a LOT worse if i didnt get the 550+. We use it multiple times a day letting the pup out on our acreage. While hunting, you can check at a glance where and how far away they are. No toggling through screens. Probably one of the best things about it is the tone, which i use for recall. At home, if it says shes a little far away she gets a beep or 2
. If thats ignored she gets a few more. Usually it doesnt come to it, but if she ignores it again, she gets remind via stimulation to get to the house. In the field, it allows me to hunt with her in range without saying a word.
