Never hiccupped once
I just experienced a three-dog jailbreak. And they had at least fifteen-minute head start on me. Escaped through three open doors. Massive failure on my part. I grabbed my phone and opened Fi, and initiated Lost Dog Mode. Immediately I knew which direction to head. I was amazed at how far they'd gotten. Only our Husky had a tracker, but the other two were right behind her. Within minutes I had them in sight. I got a hold of the Beagles right away. The Husky decided to play games. Fortunately, she was distracted by another dog down in the campground they were traipsing around in (and oh yea, they went for a lake swim, too). With Husky in hand, we haded home for treats. Fi never hiccupped once. I had immediate location updates, even with very hilly terrain and trees. Fi proved itself today!
