Over-the-Band Design
Our Fi-compatible buckle, quick-release, and slip collars use an over-the-band design. The Fi Series 3/3+ device sits on top of the band, attaching securely via Fi-provided links. This relieves stress on the tracker and means the collar stays intact even if the device detaches. Clean, low-profile, and built for every trail, swim, and muddy romp.
Inline Buckle Design
Built specifically for Fi Series 3/3+, the inline buckle collar keeps the device flush with the band via Fi links - clean, streamlined, and fully integrated.
