When teamed up with the Astro 220, this system will have you hunting in no time. The DC 40, in combination with the Astro 220 pinpoints your dog's position every 5 seconds. An innovative charging connection with a flashing LED-charging indicator lets you know when the battery is ready to go. You can extend the battery life of the DC 40 by changing the position transmit rate from 5 to 10, 30, or 120 seconds, enabling the DC 40 to work up to 17-48 hours in the field on one charge. You will know if your dog is pointing, sitting, moving or treeing. Where your dog is. Where it's been. How fast it's moving and how far it's gone.
