If you’re shopping for a Fi compatible dog collar, chances are you’ve already invested in the Fi GPS tracker — or you’re considering it to keep your dog safe and accounted for. With many options available, it’s important to remember that not every collar that fits a Fi device works properly.
Modern Icon is proud to be a Fi® Maker; our handcrafted 1.5″ Summit Collar gives dog owners peace of mind to let their pets explore with seamless Fi® integration. Easily charge the tracker without removing it from the collar.

So, how do you avoid a collar that causes more frustration than freedom? Let’s break it down.

What Does “Fi-Compatible” Actually Mean?
According to Fi®, a truly Fi compatible collar must allow the Fi Series 3 or Series 2 module to charge without being removed from the collar.
If you need to unclip or remove the tracker just to recharge it, it’s not truly compatible — even if the product page claims otherwise. That simple detail makes a big difference in daily life.
When “Fi Compatible” Isn’t Really Compatible
The problem? Some collars only “fit” Fi — they weren’t actually built for it. Many collars on the market fit the tracker, but manufacturers do not actually design them to integrate with it. These DIY setups rely on zip ties, hook-and-loop straps, or retrofit brackets.
They might work for a while, but over time they can:
- Loosen or wear down the Fi module
- Break alignment with the charging base
- Require constant adjustment or reattachment
- Lead to lost or damaged gear (and lost dogs)
This is especially true for Fi Series 3 collars. The charger’s alignment matters more than ever because of its sleek, elevated design.
What to Look for in a True Fi Compatible Collar
Here’s what separates a truly Fi compatible collar from a workaround:
- Uses Fi-approved endlink brackets (not DIY mounts)
- Allows charging without removing the Fi module
- Secures the tracker without twisting or shifting
- Keeps the module protected during everyday wear, water, and play
- Lists Fi Series 2 and Series 3 compatibility clearly
