This rugged, all-weather collar combines a high-sensitivity GPS receiver and VHF antenna into an all-in-one transmitter that works with the Astro 320 and Astro 220 to safeguard against your dog getting lost. Astro DC 40 sports a durable 1 in. orange polyurethane collar that fits most e-collar receivers — eliminating the need to put two separate collars on a dog. Plus, Collar Lock uses a 4-digit PIN number that helps prevent others from seeing your dog’s whereabouts.
