Keep the gear your dog loves. Add a compatible Fi tracker.
PRODUCT DETAILS
What to know before ordering
GPS tracking on your current collar or harness.
Fits Fi Series 2, 3 & 3+. Keep the gear your dog already wears and add a compact mount for your Fi tracker. The adapter wraps around a compatible strap and holds the module close to the gear.
Choose your Fi series, strap width, and hardware finish. You don’t need to choose between collar and harness—the Compact works with either when the strap fits.
Choose your tracker and strap width
Select Fi Series 2 or Fi Series 3 / 3+. Series 3 and 3+ share the same Compact Adapter fit.
Measure the strap where the adapter will attach. Sizes: Universal Fit (works on most ¾–1 inch collars), 1¼ inch, 1½ inch, 1¾ inch, and 2 inch.
Fi Mini needs the separate Fi Mini Compact Adapter. Fi Ultra accessories are coming soon; this adapter does not fit Ultra.
Compact or Behavior Adapter?
Choose Compact for a low-profile GPS mount on compatible gear. If you use Fi 3+ on a collar and want placement designed for behavior tracking, choose the Fi 3+ Behavior Adapter.
The adapter positions your tracker; the Fi device and app provide the tracking features.
Handcrafted in Alaska with durable webbing and marine-grade hardware.

WHY A MARTINGALE?
Secure when needed. Relaxed when it isn’t.
A martingale is a limited-slip collar. It sits relaxed during normal wear and reduces its opening when leash tension is applied, helping prevent a dog from backing out of the collar.
The standard EDG martingale is built without a buckle, so it must pass over the widest part of the head and then adjust at the neck. If you add the Tactical Buckle, the collar opens instead and neck measurement drives the size.
The goal is secure, properly fitted movement—not continuous pressure.
