+1 on the sit means sit. It’s also sold under SportDog. Great simple and economical collar with everything you need (short of GPS), and nothing you don’t.
Not to hijack the thread but has anyone used the Dogtra Pathfinder 2 with it's E-fence options? Got an acre lot and it would be nice to get notified when she's beginning to wander off the property as I'm distracted doing whatever else outdoors?
