Fi 3/3+ Compatible Martingale Collar Without Buckle | 40+ Designs

Best Fi Compatible collars on the market!

This was our second or third time back to the SeaFlower store, and the products continue to impress. The patterns offered are amazing, and the collars hold up well against our destructive Huskies. We prefer the no-buckle Martingale collars and stick with these when upgrading from Fi2 to Fi3 GPS units. We also picked up some matching leashes this time.

It fits better than the original

Beautiful fabric, love the martingale collar and its so comfy she sleeps in it. The original fi was too big for her, thank god I found this great company!!! Thank you

Beautiful & Sturdy

I love this martingale! It's well constructed and striking! The ring you attach the leash to is a little too heavy. My pup seems to shy from it when I go to put it on. I don't think he likes how heavy it feels between the heavy-duty hardware and the weight of the Fi unit itself. I really hope he gets used to it. I use a thick martingale when we go to obedience training and it wasn't working to ALSO be wearing his Fi collar. I bought this Fi compatible martingale so he would only need to wear one collar to training. When we get home, I switch back to the regular collar, so the Fi unit needs to be removed from his SeaFlower collar and put back on his Fi collar. It only takes a minute or two. I gets tons of complements on the pattern (blue smoke) too!
