Getting what you need for the hunt is now a little easier. You can purchase the entire Astro bundle or as many DC 50 collars as you need. And your 320 is compatible with every DC series dog collar. The DC 50 is our only dog device with remote bark detection and improved battery life (including battery preserving rescue mode). The improved battery life means when you set your update rate to every 5 seconds the battery lasts 26 hours. In rescue mode, the battery lasts 54 hours, giving you more time to find your lost dog.
