Product Specifications

When teamed up with the Astro 220, this system willhave you hunting in no time. The DC 20, in combination with the Astro 220, pinpoints your dog's position every 5 seconds and runs for 17 hours. You can extend the battery life of the DC20 by changing the position transmit rate from 5 to 10 or 30 seconds, enabling the DC20 to work up to 36 hours in the field on one charge. You will know if your dog is pointing, sitting, moving or treeing. Where it's at. Where it's been. How fast it's moving and how far it's gone.
