Garmin Astro - Dog Tracker, Dog GPS

Tired of searching for your hunting dog in tall grass or dense cover? Pinpoint your dog’s position and know exactly where he is, even when you can’t see or hear him, and leave the hunting entirely to him. Includes the Astro 320 handheld unit and DC-50 transmitter collar!

A Dog GPS that tracks their every move.

The Astro GPS dog tracking system includes a bright color-screen handheld GPS device and the rugged, orange polyurethane DC-50 GPS dog collar.

The collar strap accommodates most e-collar receivers — eliminating the need to put two separate collars on a dog. Just slip your compatible e-collar receiver right over the DC-50 strap.

Plus, Collar Lock creates a four-digit PIN number that helps prevent others from seeing your dog’s whereabouts — a useful feature in field trials to ensure that an Astro is used only as a recovery tool when a dog in competition becomes lost.

Track Dogs in Dense Cover

The Astro 320 Handheld GPS system

As often as every five seconds, your dog’s DC-50 transmits his position to your Astro 320 handheld. You can see his current location and a trail of where he’s been on the Map page of your handheld.

Switch over to the Dog Tracker page to view a compass pointing to your dog’s location as well as his current status: whether he’s running, sitting, on point or treeing quarry. The new three-axis electronic compass lets hunters accurately view their dog’s position when holding the handheld at any angle.

Astro can also sound an alarm to let you know instantly when your dog goes on point. In addition to audible alerts, Garmin has also incorporated a vibration feature on the Astro 320.

You can track up to ten dogs at one time with Astro, at a distance of up to nine miles away (depending on terrain). The system transmits information by line-of-sight, so it reaches farthest in flat, open territory.

Rugged and Durable Collar Design

The new DC-50 collar/transmitter is an upgrade to the previous DC-40 collar. The DC-50 features a top-mounted high-sensitivity GPS antenna to improve position performance. The receiver's ability to track additional satellites using the GLONASS system helps locate the dog's position more quickly and maintain GPS location even in heavy tree cover or deep canyons.

A braided steel VHF antenna, with additional length, reliably sends the dog's position data straight to your Astro handheld. As an added bonus, the DC-50 will now incorporate innovative bark identification technology so that dog owners will know if the dog is barking even if they are out of audible range.

This new DV-50 is waterproof (up to 10m), rugged and reliable!

The charging connection has been completely redesigned, with the charger clamping around a housing that has no recessed areas for mud to accumulate. Even the LED charging light on the collar has been reconfigured to flash while charging, and glow solid when fully charged.

Astro shines when you’re out on the hunt, but it also excels in getting you back to your truck at the end of the day, or even back home again. In fact, the Astro handheld has all the features of Garmin’s top-line handheld outdoor devices, including a barometric altimeter, electronic compass, microSD™ card slot, celestial information, area calculator and rugged, IPX7 waterproof exterior.

With optional detailed city street maps, you can search for over 6 million points of interest and create a route on roads with exact turn-by-turn directions.

Unleash the Full Potential by Adding Detailed Maps to the Device

Garmin's unprecedented ability to upload detailed maps to the handheld unit is what makes this device so amazing. Never get confused where you or your dogs are by over-laying Satellite imagery, Topo, USGS, and NRC raster maps directly on the main display. Each mapping addition allows you to use overlays, giving these maps the ability to work with one another at the same time by using layers.

Astro 320 Enhancements

The Garmin Astro 320 GPS Dog Tracking Handheld DeviceThe Astro 320 improves user interface with a simpler menu structure and sophisticated graphics thanks to its vibrant, sunlight-readable 2.6”color display.

Both durable and waterproof, Astro 320 is built to withstand the elements. It features the legendary toughness built for the rigors of the outdoors – be it dust, dirt, humidity or water, none of which are a match for this essential hunting companion.

The 320 features a built-in worldwide basemap with shaded relief, plus support for enhanced mapping such as BirdsEye™ satellite imagery, Topo maps, and Garmin custom maps.

With an optional BirdsEye Satellite Imagery subscription, hunters can pinpoint buildings, powerlines, and even individual trees – directly on their Astro 320. Hunters know, for example, if their dog has crossed a creek or is nearing a dangerous road.

Garmin’s free BaseCamp software allows hunters and trainers to download, view and save their dog’s tracks to a computer for viewing later – a great tool for evaluating performance.

A refined user interface streamlines what is displayed on screen by allowing dogs that are outside the current zoom level to have their location notated in the display's margin. The user can also choose the amount of each dog's tracklog displayed, or toggle it off completely to avoid cluttering the map.

This rugged handheld also has a built-in vibration motor to support silent alerts in addition to audible tones, a 3-axis digital compass (allowing the hunter to hold the handheld at any angle), improved reception range, a fully rubberized outer coating with an over molding for a better grip, a new keyboard design, and onboard memory for storing additional mapping (1.7 Gigs).

The handheld also features a handy keypad lock so buttons aren’t accidentally pushed while being carried in a pocket or through thick brush. The orange trim color is great for hunters and especially helpful for visibility if the handheld is dropped or misplaced.

Dog handlers can wirelessly transfer waypoints, tracks, and even their dog’s tracking settings to other Astro 320 users.

See all your dogs at once

Track up to 10 dogs at once by adding additional DC-50 GPS tracking collars to the Astro system. It's a breeze to setup, and you'll quickly be able to see what all of your dogs are doing and collect data for each of them. From a couple of dogs to a lot, we have you covered.

The GPS tracking system is a real benefit.

The Astro 320 can track up to ten dogs per receiver at once, and the collar gives location updates every five, 10, 30 or 120 seconds (user selectable). Battery life is 17-48 hours (based on update rate) on the rechargeable DC 50 collar and 24 hours on the Astro 320 receiver, which is powered by two AA batteries. The DC-50 collar takes 4 hours to fully charge. Both the DC 50 collar and the Astro 320 receiver are waterproof.

The Astro GPS Dog Tracking System requires very little configuration straight out of the box, and is extremely simple to use. Once the transmitter and receiver acquire a GPS signal, the receiver automatically lets users know the location of their dog. There are no subscriptions or setup fees required to use the device.
