Fi Bands are interchangeable but limited to their series. Our bands are designed so you can easily swap the band for a new color or style.
Below, you'll find videos with steps to replace the bands for each Fi Collar Series Band.
Please note, the Fi Band is designed with the pattern on the inside of the band.

How to Change a Fi Series 2 Collar Band
Collar Strength
Series 3+ or Series 3
The Fi Series 3+ and Series 3 Collars sport a full stainless steel body frame that can sustain 500 lbs of static force.
Series 2
Constructed from fiber-reinforced nylon, Fi Series 2 is reinforced with an internal end-to-end metal frame and tested for 300 lbs static pull force limit.
*For dogs with specific behavioral issues or pullers, we recommend using a harness in addition to the Fi Collar for tracking. Depending on the impact speed of a shock load (like a squirrel sighting), the energy delivered to the hinge can exceed a 300 lbs static pull.
Ensuring a Secure Fit
For maximum security, ensure the band connectors on your dog's Fi Collar always remain as flat as possible. Proper fit helps prevent excessive movement or rotation of the Fi Device, reducing the risk of strain on the hinge. See Sizing and Fit for further instructions to ensure appropriate size and fit.
