What if I already have a Garmin Astro?
Garmin has made the DC-40 collar so it works with the original handheld. If you have a system with the DC20 or DC30 collar you can run the DC 40 collar without purchasing a completely new system or handheld 220 receiver.Can I get a DC40 collar and run it with my old collars?
You sure can. The Garmin Astro Handheld will track up to 10 dogs. If you want to run your system with an original DC 20 or a DC 30 on one dog and add a DC 40 for the next dog you can. The handheld does not "know" the difference between them and will add the DC40 one just like the old one.
Garmin has added a few new features to the DC 40 that are exclusive to the 40. If you get a DC 40, you can update your handheld software and use these new features in an older unit.QUESTION: If we do lose a dog, how easy will we be able to locate him once we get back in range?
ANSWER: Easy! The Astro tells you once it has lost a signal. It marks the last known location of your dog and then searches for a new signal without you having to do anything. The times that I lost a signal all I had to do was move in the last known direction of the dog and the Astro would pick up the new signal long before I got close to the dog. This feature worked better than I ever expected.
When Your Dog Runs Out of Range, What Then?
-- The biggest difference with an Astro is that we will be able to see the exact point that the signal drops off. We will also have the advantage of knowing the last spot that we were able to get a signal. This allows you to immediately go to the last known location and pick up a current location.
