  • T5 Mini Collar perfect for Smaller Dogs

Garmin Astro® 320 Combo with T5 Mini Collar


 Product Description

Includes specialized MINI T5 Collar for smaller dogs.

The premier high-sensitivity GPS-enabled dog tracking system for sporting dogs....with T5Mini collar.

Pinpoint your dog's position and know exactly where he is, even when you can't see or hear him. Includes the newest, Astro 320 handheld and latest T5Mini transmitter collar (perfect for smaller beagles, terriers, feist, etc.).

Tired of searching for your hunting dog in tall grass or dense cover? Now you can leave the hunting entirely to him.

See Your Dogs' Every Move

The Astro system includes a bright color-screen handheld GPS device and the rugged, orange polyurethane T5Mini collar.

The 3/4" collar strap accommodates many e-collar receivers — eliminating the need to put two separate collars on a dog. Just slip your compatible e-collar receiver right over the T5Mini 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.

Attach Collar and Go

To get started, just take Astro outdoors and turn on the handheld and transmitter to acquire GPS satellite signals. Then attach the T5Mini to your dog. Now you're ready to turn him loose — no other setup required!

The T5Mini collar/transmitter features a top-mounted high-sensitivity GPS GLONASS receiver for increased signal reception. 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.

The T5Mini's reliably sends the dog's position data straight to your Astro handheld.

This T5Mini is waterproof (up to 10m), rugged and reliable and includes a SLEEP MODE feature to help save battery life (activated from the handheld).

Track Dogs in Dense Cover

As often as every five seconds, your dog's T5Mini transmits his position to your Astro 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. The 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.

Astro boasts a high-sensitivity GPS receiver that can track your dog's position even in the densest cover.

You can track up to ten dogs at one time with Astro, at a distance of up to four miles away (depending on terrain). The Astro can track DC-40, DC-50, T5, T5Mini, TT15, or TT15Mini dog devices (each sold separately).

The system transmits information by line-of-sight, so it reaches farthest in flat, open territory.

Count Your Coveys

After you've captured your quarry, mark the exact spot with Astro's Covey Counter, a special waypoint that tells you the exact location, time of day and elevation where you found your prey, as well as the number of birds you flushed and took from that location.

Astro lets you save other special waypoints, such as "Truck" and "Lodge," so you can save the location of these places quickly and easily for each hunt. Astro also offers special waypoint icons to represent food plots, tree stands and other hunting-related points.

Experience Full-featured GPS

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.

Astro 320 

The 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.

Now offering two new included antenna options, the extended range antenna can increase the tracking range by up to 30%. Thanks to the redesigned antenna, the maximum range between the Astro 320 and a Garmin tracking collar can achieve up to nine miles in flat, unobstructed terrain.

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

LED beacon lights on the dog device are perfect for low-light conditions or night use - visible up to 100 yards away.
