  3. Updating software


NEW for 2016 Garmin will introduce a DC 50 Collar update allowing the ability to track DC 50’s with the new Astro 430 and also with Alpha 100 Handhelds.

    Garmin will release a New Update for the Astro DC50 collar that makes the DC50 compatible with the 430.  This software update will also make the DC50 collar track on Alpha 100 devices as a Track only collar.   To update your DC50 collars so they will track with the Astro 430 or with Alpha 100 simply connect the DC50 collar to your computer and run the Garmin WebUpdater program.   After the Update, the DC50 will be able to pair to an alpha and Astro 430’s. The one limitation the DC50 will have is in order to change the settings for the DC50 (ie. Update rates, and Communication ID numbers)  you will need to be in close proximity (10-20 feet) from the DC50.  (In comparison the T5’s and TT15 collars can be controlled at greater distances (up to several miles) when changing settings such as Update Rate, and ID numbers.


Key features of the Garmin Astro 430/T5 Tracking & Training Combo

  • Track 20 Dogs: On your Astro 430, you are able to track a total of 20 collars.  Due to hardware limitations, you cannot track other Astro 430s

  • DriveTrack 70: The New Astro 430 is compatible with the New bigger screen DriveTrack 70.  When you purchase the DriveTrack 70 you can enable the Astro 430 to wirelessly transmit and share your dog list to the DriveTrack.  This makes it much easier to track your dogs in your cab while hunting out of your truck.

  • Other Wearable devices:  The Astro 430 is also compatible with wearable watch devices. When paired with a Fēnix 3 watch for example you can see distance and direction of your dogs by simply looking down at your watch.

  • Change Collar Settings : The Astro 430 makes it easy to change your collar setting while out hunting. This change enables you to change update rates and rescue mode while at any distance that you are tracking the device.  (NOTE: The only collar that will not be able to do this is the DC50 which will need to be in Close range to the handheld to change settings.)

  • Alpha Compatibility: With the New Astro 430 you can now track the same collars as Alpha users.  This is great for People who don’t want or need the Training features of the Alpha Track and Train but still hunt and share dogs

  • Track and Control Codes: When linked to an Astro 430 users can Share their dogs with other Astro 430 user’s or Alpha 100 user's ; allowing Track only, or full control of their collar.  User’s can give Track only permission to their buddies or they can provide control information. When tracking only permission is given they will not be able to change the collar settings such as update rates, ID number or turning the lights on or off.  When Control permissions are given the second user has full access to Change all settings of the collar.

  • State of the Art GPS Tracking: It is now less likely for your collar to lose satellite reception while hunting in heavy cover or deep canyons due to the highly sensitive top mounted GPS module that now tracks with GLONASS. With GLONASS,both your Handheld and collar is able to receive signals from a total of 49 earth orbiting satellites. That’s 21 more satellites than the 320 and Early versions of the Astro..

  • Rescue Mode: This feature, if enabled by your Astro 430, increases the amount of time you have before a  T5 collar battery dies. This allows more time for you to find and recover your treasured dog. As soon as the collar detects its battery has decreased to 25% of its full charge, it automatically begins to conserve its battery life by changing the update rate from its preset setting to a 2 minute update. Remember, this feature must be enabled manually by the user with the Astro 320 handheld.

  • Pre Installed Topo Map: The Garmin Astro 430 comes preloaded with 100K topo mapping for the entire U.S. This will provide topographic detail, roads, creeks, streams, rivers and lakes, etc.

  • Faster Update Rate: Capable of turning the collars down to 2.5 sec update rate to keep a closer eye on your dogs.

  • Hunt Metrics: With the Astro 430, you now have the ability to collect performance data from your dogs such as distance traveled, and time in the field.

  • Customize Your New Hunt: New on the Garmin Astro 430 is the ability to customise your New Hunt. Choose which dogs you would like to reset the tracking data on and which dog’s tracks you would like to keep on screen.

  • Durable VHF Antenna: There are two antenna choices to choose from for the Garmin T5. They are the 22.5” or 18.5”. The length and flexibility of this VHF antenna with braided steel core increases range and durability. Both are included in the purchase of an Astro 430 and T5 bundle from Double U Hunting Supply.

  • Quick Collar-Strap Changes: The Garmin T5 uses the same collar strap design as the Garmin Alpha TT10, and Astro DC50 collars. It is quick and easy to switch out collar straps with no tools needed.  Just slide your favorite colored collar straps through the integral channels on the Garmin T5. All universal 1 inch D-ring collar straps or even the Tri Tronics EXP straps can be put on your GPS dog tracking collar in seconds. We have also put a training unit like the Tri Tronics EXP on the same strap as the T5 with ease. This eliminates excessive collars on your dog.

  • Improved Charging Port: The T5 charging port comes standard with a USB interface. This presents 3 different ways to charge the collar: an AC outlet, a vehicle charge port, or the USB port on a computer. The ability to plug it right into a computer is convenient when you're T5 tracking collar needs a software update. All that’s required for an update is to attach the charging clip, plug the T5 dog tracking collar into a computer and run Garmin Webupdater.

  • Helpful Tone Indicator: An appreciated difference from previous collars is that a tone will sound when adding a collar to your handheld. This confirms you’ve added the correct collar when there are other collars close by. For most of the settings on your T5 the handheld will tone when the setting has successfully been changed. For example: when you change dog type to “treeing dog” your T5 will beep to let you know you have successfully completed the task.

  • Adjustable Dog Status:  Using the updated Astro 430, you can change the status for each of your dogs wearing a T5 to reflect what they’re doing. Your options are 1) Pointing, 2) Treeing, 3) Auto, and 4) None. This lets your Astro know that when your dog is sitting idle he or she could be on point or have game treed.

  • Protective Antenna Sleeve: The T5’s antenna sleeve protects your antenna from wear and tear but also keeps it erect while still receiving satellite signals. This thick rubber sleeve will have you saying good-bye to zip-ties and electrical tape and hello to an easy to clean and durable antenna that stays upright without all the trouble.

  • Basecamp: The Garmin Astro’s USB port makes it easy to plug it right into your laptop. Using Basecamp, you can track your dogs on your laptop screen instead of the handheld screen. This can be especially convenient when hunting out of your truck, allowing the use a larger screen.

  • Covey Counter: Record the specific location of coveys. You can also record the birds in a covey and the number of birds taken from the covey using waypoints.

Astro 430 T5 Bundle Batteries and Battery LifeBattery Pack

Garmin Astro 430 Handheld Battery Life:

NEW!:  The Astro 430 Handheld can be ran using one of three different battery types (batteries not included) Note: Garmin estimates run time up to 20 hours, however in our Real life experience we have had a difficult time getting 20 hours.  In extreme usage we have seen as little as 4.5-5 hours of battery when using it consistently with a full 20 dog list full.

  1. Rechargeable NiMH battery pack

    1. Garmin makes this rechargeable battery pack, which allows you to recharge your Astro 430 at home and in the vehicle just like an alpha 100

  2. AA- Alkaline batteries

  3. AA Lithium ion rechargeable batteries

T5 Tracking Collar:

With rescue mode on, the T5 tracking collar has approximately 40 hour battery life. Here’s how:

10 second update rate means around 27 hours (before battery reaches 25%)

When the battery reaches 25%, rescue mode changes the update rate to 2 minutes

2 minute update rate means about 16 additional hours

Total: approximately 43 hours


Buddy’s Summary and comments about compatibility of the 430

“This device could be one of the more confusing products that we have seen Garmin Launch to date regarding the Astro product line. Essentially the Astro 430 is not compatible with any previous handheld version of the Astro product, however it’s fully compatible with all the Alpha Products. So it’s easy to question why it’s called an Astro and not a “Alpha track only”. It even took me a while to understand the thought process for naming this product an Astro 430. To really understand this I think this is a Long term decision vs. a Short time decision. If we fast forward 2 years from now this will likely make sense and will be easier to comprehend, All (Active) collars that Garmin will be selling in the future will be compatible with all handhelds that Garmin offers from here on out.The Astro users will be able to hunt and track with Alpha users. Looking back to when the Astro was first designed, there were some things that Garmin did early that were clearly a mistake. One of the most important was designing the first Astro units with the 10 Dog Limitation, If Garmin could go back in history and Re-design the Astro 220 to communicate more like the Alpha we would have seen them do that. Having their Astro and Alpha products track using the same style of communication will help them focus their efforts and harden the platform. They will also be able to use their resources for other projects like the DriveTrack 70, AND Fenix watch. I know this step will be frustrating for users that have the Early 10 Dog systems, (Astro 220, and 320)  but sometimes difficult decisions are made for long term objectives. DC30’s DC40’s and 220’s have already been discontinued and are no longer supported. We anticipate that 320’s will be discontinued as well over the next year or two.    At Double U we are servicing those products and will continue to do so with the resources we have. Our recommendation is for users to consider moving to the Alpha 100 or the Astro 430 when it is convenient for you, In the short term it might not make perfect sense,  however In the long run you will be in a good position and save yourself some headaches by having products that are using the current 20 Dog communication platform. We do not see any reason Garmin will be leaving this 20 Dog Platform in the near future.



Frequently Asked Questions for Astro 430 T5 Bundle

Q: Can I track the same collars with a Astro 430 and an Alpha 100?


A:  Yes, the Astro 430 and Alpha 100 can simultaneously track DC50s, T5, TT10, and TT15s (*DC50s  and Alpha 100 will need a software update)

Q:  Why isn’t my Astro 220 or 320 compatible with the Astro 430?


A:  Garmin has moved the Astro system to the 20 dog communication style like the Alpha 100. This makes them unable to communicate with the 10 dog systems such as the Astro 220 and 320. Basically the Astro 430 will act like an Alpha 100 without the training portion.


Q: What are the similarities and differences between the Astro 430 and Alpha 100?


A:  As stated above, the Garmin Astro 430 can run on a 20 dog communication style just like the Alpha 100, it can also track the same collars at the same time as the Alpha, and communication settings can also be changed at range. There are a few areas where they also differ, one obviously being that the Astro 430 is operated via buttons vs touchscreen. The 430 also does not have any training features at all and cannot track other handhelds like the Alpha system.
