The GPS Dog Tracking System.

This is the dog tracking system that employs a small GPS receiver attached to your dog's collar that alerts you when he goes missing or leaves a defined area and notifies you via text message or e-mail. You can then instantly pinpoint your dog's whereabouts through the manufacturer's tracking service (12 month subscription required) that provides unlimited on-demand reports of your pet's current location 24 hours a day via toll-free phone, web maps, e-mail, or cell phone text alerts. The Assisted GPS technology (the same used by emergency services) uses GPS signals and cellular networks to track your dog's location to within 30'. You can also create up to 10 safety zones (5 active simultaneously); once your dog crosses the boundary, you are promptly notified of his current location via text message to your cell phone or by e-mail--you can even track his escape route on the Internet. The lightweight, water-resistant locator is powered by a Lithium-ion battery that provides up to five days of operation on a 4-hour charge from the AC adapter. Recommended for dogs over 15 lbs. The required 12-month tracking subscription is $14.99 per month, or $9.99 per month for the first six months with pre-payment. 2 3/4" L x 1 3/4" W x 3/4" D. (2 1/2 oz.)
