Extra Dog Tracking transmitter for use with Astro System - to track multiple dogs
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® 220 to safeguard against your dog getting lost.
The all-new DC-40 sports a durable one-inch orange polyurethane collar strap that fits most e-collar receivers — eliminating the need to put two separate collars on a dog.
Plus, Collar Lock uses a four-digit PIN number that helps prevent others from seeing your dog’s whereabouts.
Attach Collar and Go
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 handheld 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 D-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 a single charge.
You will know if your dog is pointing, sitting, moving or treeing. Where your dog is. Where it’s been. How fast he's moving and how far he’s gone.
