This seems to be the only wireless fence that can cover an area larger than an acre. That is a downfall of many wireless fences.
This Border Patrol kit covers enough space for my fence, but also has a dog trainer and tracking feature. I don't really need that part, and had a little trouble with the manual being so full of info on everything.
Another thing to mention is that the collar is really bulky. Luckily, my dog is a German Shepherd, and it's not too bad on his neck. This definitely wouldn't work on a smaller dog.
It cost 600 bucks, but as long as the fence holds, it's money well spent. I wasn't about to go burying a lot of wire.
I would more recommend this to someone who could take advantage of all the included features of this kit. However, I'm happy. : ) (Posted on 2/5/2016)

I like that I can take my pets hunting, then when I am home I can contain and train my dogs. Nice system and easy to navigate on the remote. (Posted on 12/21/2015)

This system gives my dogs a lot of space to run their little hearts out through my property. 800 yards is 6.5 football fields, go figure! Also the trainer is a plus and not an extra collar on top of the collar for the containment. I will recommend this to all my friends, (Posted on 10/26/2015)

Finally a system that has all three things I was looking for, I do wish the had a smaller collar for my little runt terrier. (Posted on 8/5/2015)
