If your dog or cat is prone to getting lost, or you frequently go on adventures together, you can save 30 percent on Fi pet trackers through October 25th when you enter coupon code SCARY at checkout. The sale includes several satellite-connected trackers, including the Fi Ultra GPS we previously tested, which is down to $209.30 after the discount. That effectively brings it down to its original launch price.

The IP68-rated Fi Ultra is fully waterproof, even in saltwater, and lasts up to five days, depending on how active your dog is. The accessory — which conveniently attaches to your dog’s collar or harness — uses a combination of LTE, GPS, and Starlink satellite coverage to track your dog’s current location and recent history, even in cellular dead zones; it can also send noise and vibration alerts to catch your canine’s attention.

We spent time with the Fi Ultra earlier this year, testing it in a remote location in South Carolina. While the tracking was precise, the two- or three-minute update interval could be problematic for fast dogs, and it drained the battery quickly in Lost Mode (we barely got two days on a full charge). It’s also fairly sizable, making it a better fit for larger pups.

Unsurprisingly, you’ll need an active subscription to use the Fi Ultra’s tracking features, though you’ll get a discount on your first term, with six-month, one-year, and two-year plans available that offer lower overall monthly rates. For example, a one-year plan is $99 for the first year, and $189 each year after. However, the plans only work in the United States and offer no satellite coverage in Alaska.
