If you want to learn everything there is about this improved model and determine whether it is truly worth your money, you can find all the answers you seek in this honest Garmin Astro 430 review.
How Garmin Astro 430 Works
The Garmin Astro 430 dog tracking system consists of a handheld locator and 1 or more dog tracking units that come with specially designed collars. The system employs the GLONASS navigation system and GPS technology to triangulate dog and dog owner locations and it uses radio frequency signals for communication.
During live tracking, the dog units and the handheld locator use their high-sensitivity GPS receiver-transmitters to determine their exact positions via communication with GPS and GLONASS satellites. Then, they employ their radio antennas to communicate among one another and transmit information within line of sight.
The result of the use of these technologies is location information shown on the display of the handheld locator. The information is refreshed within seconds, allowing for near-real-time tracking. The dogs’ locations are displayed relative to the dog guardian’s location, with both distance and direction data provided.
Apart from GLONASS, GPS, and radio frequency technology, Garmin Astro 430 does not use any additional services. It is independent of cellular networks and the Internet, so it can work in urban areas as well as the wilderness. A single locator can be used in combination with up to 20 tracking units.
Garmin Astro 430 Design
The design of Garmin Astro 430 is not highly attractive, but it is rugged and gives the impression that all the components are built to last. Both the handheld locator and the tracking units with collars feature a black-and-bright-orange color scheme and they are made of durable, high-quality materials, including heavy-duty plastic and stainless steel.
The handheld locator measures 6.3 inches in height, 2.4 inches in width, and 1.4 inches in depth. It weighs 9.2 oz. with batteries included. It features a top-mounted GPS antenna, a braided stainless steel radio antenna, and a large 65-K color TFT display measuring 2.15 inches in height and 1.43 inches in width.
The tracking units come in 2 variations known as T5 and T5 mini. The T5 unit is designed for larger dogs with a neck circumference of 9.5+ inches while the T5 mini unit fits dogs with a neck circumference under 9.5 inches, although it is not suitable for smaller dog breeds.
The T5 tracking unit measures 1.74 inches in height, 3.5 inches in width, and 1.85 inches in depth. It comes with a 1-inch orange collar strap and weighs 6.6 oz. (9.3 oz. with the collar). The T5 mini tracking unit is somewhat smaller, measuring 1.8 inches in height, 3.1 inches in width, and 1.4 inches in depth. It comes with a 0.75-inch collar strap and weighs 5.1 oz. (7 oz. with the collar).
Both the T5 and T5 mini tracking units come with top-mounted GPS antennas. T5 comes with both standard and extended range radio antennas while T5 mini only comes with a standard stainless steel radio antenna. Due to their great weight and size, the tracking units are not suitable for cats and they can only be comfortably worn by larger dog breeds.
Garmin Astro 430 Technical Specifications
When it comes to tech specs, Garmin Astro 430 sure does not disappoint, as it offers everything from great accuracy and communication range to night light, vibration, resistance to water, dust, and dirt, and more. Here is a full overview of the tracker’s technical specifications.
Garmin Astro 320 is not shockproof, but it does feature a nice rubberized coating that allows it to withstand bumps, blows, and rough play. Furthermore, it is impervious to dust and dirt and it is not prone to malfunctions.
With an IPX7 rating, the handheld locator can withstand harsh weather and it is resistant to splashes, rain, and snow. The tracking units boast 1 ATM rating, so they can withstand submersion in water of up to 33 feet. However, letting your dog swim with the tracker on is not a good idea.
The handheld locator can use either a NiMH pack or 2 standard AA batteries (not included). Its maximum battery life is 20 hours. The T5 and T5 mini tracking units come with rechargeable lithium-ion batteries. T5 has a battery life of 20-40 hours. With T5 mini, battery life ranges from 16 to 30 hours.
If you opt for the T5 tracking unit, you get to enjoy a communication range of up to 9 miles. T5 mini’s maximum range is 4 miles.
Combining the benefits of GPS and GLONASS, Garmin Astro 430 provides highly accurate location information with a mean accuracy of 12 feet.
The tracking units come with LED light beacons that can be remotely activated. Even with fog or insufficient lighting, these beacons allow you to identify the location of your dog from a distance of up to 100 yards.
The tracking units do not come with stimulation, tone or vibration, but the handheld locator is equipped with a vibration motor.
As stated in the previous section of this Garmin Astro 430 review, the handheld locator comes with a big transflective 65-K color TFT display with a resolution of 160 x 240 pixels.
Thanks to a mini-USB port on the handheld locator, you can transfer tracking data onto your computer using a USB cable included in the box.
Garmin Astro 430 has a storage capacity of 4 GB. You can use a microSD card for storage, but one is not included in the box.
Garmin Astro 430 Features
If you think that Garmin Astro 430’s tech specs are impressive, wait until you discover its unbelievable range of features. Although the tracker does not monitor dog activity, it comes with more special tools and options than virtually any other device of its kind. These are some of the most prominent features of Garmin Astro 430.
Garmin Astro 430 provides fresh location updates every 2.5 seconds and tracks an astounding 10,000 points of information per dog. Not only that, but it comes with a barometric altimeter and a tilt-compensated 3-axis compass for faster and easier tracking.
Unlike most pet trackers that exclusively rely on Google Maps, Garmin Astro 430 lets you load a variety of additional mapping options, from BirdsEye Satellite Imagery, HuntView, and TOPO U.S. 24K to City Navigator NT for turn-by-turn driving directions. Depending on the kind of adventure you are planning, you can opt for On The Road, On The Water, On The Trail, In The City or On The Green maps and update your map base with anything that can be of use while in the great outdoors.
It is also worth noting that Garmin Astro 430 is geocaching-friendly and compatible with Garmin Custom Maps, Garmin’s free software that lets you turn paper and electronic maps into downloadable maps for your device.
Hunters are sure to love the handy Hunt Metrics, which provide valuable insight into dogs’ hunting patterns and behavior. The information provided includes times, distances traveled, overall scores, and the number of times “on point” or “treed” events were indicated during a hunt.
Another hunter-friendly feature is the Convey Counter that lets you create up to 2,000 waypoints with location, time, and elevation data. To help you easily locate food plots, tree stands, lodge or any other important location, Garmin Astro 430 offers useful waypoint icons that let you quickly find your way around the hunting site. Waypoints can be saved so you do not have to create them again when revisiting the same site.
BaseCamp is free software that lets you plan your trips with extreme ease by efficiently organizing your maps, routes, tracks, and waypoints. It allows you to view 2D and 3D topographic map data on your computer and transfer as many satellite images as you wish.
BaseStation is another useful piece of free software designed to turn your computer into a field control center. Particularly useful to canine search and rescue teams, this software lets you view location information for up to 20 dogs on a large computer screen, with locations freshly updated every few seconds, without cell phone reception or an Internet connection.
Whether you are hunting or just having fun in the outdoors, Garmin Astro 430 has plenty of preloaded search profiles that you can choose from, including hunting, automotive, marine, geocaching, fitness, recreational, and more.
Customizable Dog Display
The customizable dog display lets you view all the key information about your dogs straight from the map, including name, direction, distance, and status data.
With Garmin Astro 430, you can access multiple dashboards from any given page and view coordinates, elevation plot, compass arrow, and everything else at once, at any point during your adventure.
Garmin has decided to compensate for the not-so-great battery life by introducing the Rescue Mode, which automatically reduces location update rate when the battery reaches 25%. That way, you get an extra 4-8 hours to locate your dogs when actively searching on a low battery.
Whether you want to share data with your hunting buddies and coordinate hunt logistics on the go or get location updates on your fēnix® 3 GPS watch, you can wirelessly connect your Garmin Astro 430 with any of the numerous compatible Garmin devices.
Apart from the features listed so far, Garmin Astro 430 comes with a multitude of extra tools and data, including area calculation, hunt and fish calendar, and sun and moon information. It is also compatible with Garmin Connect, providing you access to an online community of Garmin users where you can analyze and categorize your tracking data and share it with others.
Garmin Astro 430 Coverage
As mentioned previously in this Garmin Astro 430 review, this pet tracker does not rely on cellular networks. Thus, it can work anywhere in the world over a distance of up to 9 miles, depending on the collar you choose. However, legal regulations related to devices that use radio frequency signals vary across countries. Due to these regulations, the use of Garmin Astro 430 is currently limited to the United States.
In the future, the device may become available in Canada and other countries that are deliberating the introduction of MURS (i.e. Muli-Use Radio Service) devices.
