Fi tracker is sold separately. If you don’t already have your own, purchase your tracker HERE. 

This listing is only an ADD ON/UPGRADE option to make our collars compatible with the Fi tracker, this is not for the actual collar or Fi tracker. Please purchase one of our Rugged Series Collars, in addition to this Fi Compatible upgrade if you'd like the collar to be compatible with your Fi Tracker. 

1" & 1.5" collar widths: the end links are sewn on top of the collar to give your Fi device extra protection, & allows the collar to still be functional without the Fi tracker attached.

3/4" collar width:

  • For Series 1 & 2 Fi collars will be the in-line Fi compatible style. The 3/4" width option uses a 1" piece of BioThane to connect to the Fi end links so the Fi can be safely attached to the collar at the width it's designed to attach to.
  • For the new Series 3 Fi end links will be sewn on top of the collar.

Due to length of the Fi Smart GPS Tracker, the collar will adjust about 2-3” less than our standard sizing. Therefore, this collar will be custom sized to fit your dog depending on the neck size you select from the dropdown menu.
