Welcome to the forum.
Are your dogs rough, loose, short or long range? If they are rough and you want to start them, I would suggest getting a decent cut kit and some collars/vest first before the tracking system. If they are loose and long range id go with the tracking system first. A lot of us started with no tracking systems and managed to get by. lol
Oh and the first thing I would do, is look at your bank account, and maybe take a picture so you remember what it was like to have money in there.

They are fairly rough and would consider them short range.. Maybe some collars would be a good start. All great info and advice everyone.. Please keep it coming..
