The rugged Astro DC 40 collar / transmitter is a complete stand alone unit.
The DC 40 is an improved designed based of the popular DC 30 collar.
The DC 40 is a self-contained transmitter. It incorporates the GPS antenna / receiver, battery and electronics into one unit.
Garmin has eliminated the multiple parts of the DC 30 and combined everything into one durable smaller package. It does away with the wires that connected the GPS Antenna to the electronics. This allows the unit to be mounted on a standard plastic coated nylon collar strap.
The DC 40 Astro collar has a Whip Style RF antenna that will take all the abuse a hunting dog can give it.
The DC 40 is built tough to handle the rough terrain where your dog hunts, and it doesn't require the use of any additional counterweight, ecollar, or vest to keep the unit on the dog. Just buckle it on and go!
The new compact design of the DC 40 will also allow you the option of mounting both the DC 40 and most standard remote training collars on the same strap. eliminating the need for two straps if you run both an ecollar and the Garmin Astro on your dog.
New Charging Cradle
The DC 40 now comes with a charging cradle that snaps on to the DC 40. This new design eliminates the grooves that allowed dirt and mud to collect in the earlier versions of these collars and made charging difficult.
The DC 40 also has a system of blue lights that blink while the collar is charging and glow solid after it is finished charging. You snap your collar into the cradle and plug it up, the light will blink blue. Once it is fully charged, the light will glow solid blue.
"Collar Lock" PIN system
A new feature that has been added to the DC 40 is the option of putting a "password" protection feature on your collars.
The new "Collar Lock" feature allows you to block other people from being able to track your dog. You select a 4 digit code that the users hand held will require you to enter before it will allow anyone to track your GPS collar.
"Collar Lock" is a pull down selection that you can set on your collar if you want it. It is not required to use the DC 40, and it is easy to reset if you want to change it or stop using it.
2 Minute Update Rate
The Astro DC 40 also has a new update rate that is designed to extend battery life. The Update Rate is the time between location information being sent from the DC 40 collar to your hand held receiver. The quicker the update rate the more information you have on where your dog is and what he is doing.
Previous generations of the Astro have allowed update rates of 5 seconds, 10 seconds and 30 seconds. The DC 40 has those updates and it also has a 2 minute (120 seconds) option. This longer update rate is designed for the dog owner that wants the longest possible battery life (48 hours) and is willing to sacrifice location detail to get it.

Never go hunting without!! Reviewed: June 5, 2009
By: Crystal I.They truly are the way to go with keeping track of all your dogs at the same time. We hog hunt with them and we can tell if they are on the move and where they have been, or sitting in the same place. GPS is user friendly, I have only had a couple problems with the collars losing signal with the GPS, however Garmin Tech replaced the collar if it wasn't repairable. Overall, I would strongly recommend these to any hunter.

DC 40 Reviewed: December 3, 2011
By: Len Hart
15 dogs: Begales & Walkers. Hunting dog.
The DC 30 has twice the range and is a much better made collar. The DC 40 will not pick up nearly as far as the DC30. I will have as many as 8 dogs running deer at one time. The DC 30 never loses a signal or loses it for a very short time. The DC 40 will lose the signal within the first 1/2 mile and is very hard to catch up to. They should have left the gps unit on the top of the collar so it can always pick up a good signal.
The DC 40 collar is the "dog half" of the Garmin Astro System. It is the transmitter that relays the dog's position to the handler's Astro 320. The Astro collar gives location updates as often as every five seconds.
