Fi Series 2 to 3/3+ Conversion

If you own an Oliver & Ash Designs Series 2 Fi collar, and want to convert it to fit the new Series 3/3+, we can do that! (We are not offering modifications for collars by other Makers).

Your Series 2 collar will need to be mailed back to us, then we will remove the Fi Keepers and replace them with Keepers that fit the Series 3/3+.

You can choose 3/4” or 1” links for your Series 3/3+. You can design with the same Fi Keeper color, or change it since we need to make new ones (we are only offering to change the keeper color since they need to be remade, not other components of your collar).
We will be able to use the same holes in the collar for your new keepers, HOWEVER, we recommend that the rivet closest to the Fi unit does not go all the way through the collar (as in the Series 2 design) so that you will be able to charge your Series 3/3+ without removing it from the collar. This means there will be an unfilled hole in your collar - but it will not be visable. Please watch the video below.
