Sorry, I didn't mean the drive track helps, we use both, alot of times when the drive track give you a notification of picking up a dog and immediately loses it the unit with the short antenna will have the dog on it. It seems to work for us.

ive notice that people go to trails they have 15 or so collars program in box ,but only take 5or6 dogs.remove the ones u not using so u want be receive others collars.this take care of 1 problem.i use a 17in lap top to track my dogs.at outside hunts i keep screen on a 5mile scale and keep note pad where i can keep up with what direction dogs travel off to.u can get back on your own quicker.hope this helps.
