Fi Series 3+ Compatible Collar
As Fi users ourselves, we're so excited to finally offer Fi-compatible collars at Archie & Fitz Co!
We took our time developing and testing them to make sure they met the same standards for quality, comfort, and durability that we expect for our own dogs, and we couldn't be happier to share them with you.
We absolutely love our Fi collar and the peace of mind it provides. Being able to check in on your dog's location, activity, and adventures is something we've come to rely on every day with our own pups, which is why bringing Fi-compatible collars to our shop has been such an exciting project for us.
Our Fi Compatible Collection combines the technology you trust with the handcrafted quality and adventure-ready durability you expect from Archie & Fitz Co. Each collar is handmade using premium BioThane® and solid brass hardware, creating a collar that's ready for muddy trails, lake days, road trips, and everyday adventures while keeping your Fi Series 3 tracker securely in place.
Whether you're exploring somewhere new or heading out for your daily walk, we're thrilled to offer a collar that helps keep your best friend safe, comfortable, and connected every step of the way.

1. Choose your hardware
Solid Brass
Naturally rust-resistant and holds up well around water—no chipping, flaking, or peeling!Matte Black
Our matte black hardware is finished using PVD plating — an extremely durable process designed to prevent scratching, chipping, and wear. Unlike most black hardware found on the market (which is typically spray-painted or coated and can scratch or chip within days), PVD plating is the only proven way to create a black finish that will not wear off with regular use. -

2. Choose your style:
✨Solid
A single color throughout the entire collar for a clean, classic look.
✨ Two-Tone
Features a primary collar color with a coordinating accent color around the Fi module, creating a subtle pop of contrast.
✨ Split Tone
Half one color, half another. This style creates a bold, balanced look and lets you showcase two favorite colors in one collar. -
