The DC 40 brings together a higher-sensitivity GPS receiver and a VHF antenna, all in one modest transmitter. A vibrant, orange polyurethane collar tends to make for fantastic visibility, extreme toughness and simple preservation so you can focus on the hunt. The redesigned charging contacts are flush with the device, so they do not get clogged with dust and mud. A new flashing LED-charging indicator allows you know when the battery is charged and ready to go. You can mount an e-collar receiver up coming to the DC40, eliminating the need to have for two collars on the dog. A Collar Lock choice makes use of a four-digit PIN amount that helps avoid others with Astro receivers from tracking your dog's whereabouts. Get into the hunt with the DC 40!
