T5 Dog Tracking Collar


Available on backorder


The T-5 relays the dog’s position to the handler’s Astro 430 with location updates as often as every 2.5 seconds. You can track up to 10 dogs on a single system. Add additional T5s as needed.

The T5 is a GPS TRACKING collar only — no remote dog training collar features. The T5 can be used alongside DC-20, DC-30, DC-40, and DC-50 tracking collars. The T5 is also compatible with the Alpha 100 and PRO 550+ (tracking only). The T5 is NOT compatible with the Astro 220 handheld.

The Astro/T5 Combo comes standard with an orange collar strap. Additional collars come from the factory with a blue strap. We give you the option of 10 different strap colors: Orange, Black, Blue, Green, Red, Yellow, White, Silver, Pink, or Violet so you can easily keep up with different dogs!

AKC Competition Approved

The AKC Performance Events Department has approved the Garmin T5 collar for use in pointing breed field trials and hunting tests.

Astro T5 Collar Hardware Features:

Beacon Lights

Integrated Beacon Lights give your dog added visibility in low-light conditions.

Orange Top Mounted High-Sensitivity GPS/GLONASS Receiver

The T5 features an orange GPS/GLONASS receiver to make it easy to differentiate T5 collars from other models. The GPS/GLONASS receiver antenna is on top of the dog’s neck like on the old DC-30 but without the horrible nylon collar strap. Get better, faster GPS tracking with increased sensitivity.

Quick-Charge Li-ion Batteries

The T5 collar features a rechargeable lithium-ion battery that gives a 24-48 hour run time depending on selected update rate. Charge time is 4 hours. The built-in battery life indicator lets you know when you need to recharge your collar.


The T5 Astro GPS Collar is waterproof to 1 ATM (10 meters)

Collar Battery Run Time Chart

  • ~24 hours with 2.5 second update rate
  • ~34 hours with 5 second update rate
  • ~38.5 hours with 10 second update rate
  • ~42.5 hours with 30 second update rate
  • ~48 hours with 120 second update rate

It’s really tricky to give exact run times on the Garmin Astro T5 because there are so many variables. Collar battery run time is most affected by update rate and whether or not you use the Beacon Lights.

One Piece Charging Cradle

The T5 has a charging clip just like the DC 40 and the TT 10, but unlike these two other collars, the clip is part of the cord and not a separate piece. One less thing to lose!

Collar VHF Antenna: Tough Braided-Steel

These whip antennas take all the abuse a hunting dog can give it in the rough terrain where you hunt. The T5 comes with a VHF antenna made from BRAIDED STEEL. This antenna is the same design used on the Alpha TT 10 and 15. We have really been pleased with these antennas, and they are very tough — especially compared to the old designs on the DC 30 and DC 40.

Additional Long Range Collar Antenna

Also included in the T5 package is a 22 1/2″ Long Range Collar antenna. This longer antenna provides additional range compared to the standard 18 1/2″ antenna. The Long Range Collar Antenna is perfect for big running hounds.

Feed-through Collar Strap Design

The T5 collar strap is a feed through / collar belt loop style unit just like most e-collars on the market today. It does not require screws or a plate to attach the collar to the unit.

Coated Nylon “Glo” Collar Strap

Just like the DC 50, the T5 uses a 1-inch wide plastic coated “Glo” collar strap that is popular with most hunters and Field Trial dog owners. These straps hold up better than regular nylon or leather collars and come in 10 different colors so you can keep up with your different dogs. Choose an Orange, Black, Blue, Green, Red, Yellow, White, Silver, Pink, or Violet collar strap. Fits neck sizes between 13-inches and 22-inches and features a solid K-9 metal collar buckle with metal keeper.

USB Port on Collar

Built-in USB Port allows easy software updates — just plug your collar into your computer. Also can be used to export additional GPS dog data directly from your collar to your computer.

Astro T5 Collar Software Features:

Astro / Alpha / PRO 550+ Cross-Compatibility

The T5 is compatible with both the Astro 430 and 320, Alpha 100, and PRO 550+ handhelds (tracking function only with Alpha and PRO 550+). This now lets Alpha and PRO 550+ users who need a system they can use in competitions legally run T5 tracking collars. Also, folks that buy the Astro 430 with T5 collars can continue to use the T5 collars in the future if they ever switch over to the Alpha or PRO 550+ handheld.

Rescue Mode

When the battery on a tracking collar dies, finding a missing a dog gets a lot more difficult. When the collar battery drops to 25% life, RESCUE MODE changes the update rate to a 2-minute ping to extend battery life which gives you the maximum amount of hours to find a lost dog. Rescue mode is not the default setting. You have to turn it on under SETTINGS. I can’t think of a good reason NOT to run your collar in rescue mode because there’s no downside to using it.

Live Laptop Tracking with BaseStation: Track Your Dogs on a Bigger Screen

Using BaseStation, you can take your handheld while you’re tracking dogs and plug it into your computer, letting you view your dogs on your laptop’s screen. HOW TO: First download Garmin’s Base Station Software. Then plug your handheld into your computer’s USB port to see the Tracking screen on your computer. We’ve got guys that are working out of vehicles and they are tired of looking at a small screen all the time. They want to set up a computer in their vehicle and be able to view the tracking. You still use a handheld to track, but view your dogs on your laptop screen instead of a small handheld. Garmin says it’ll track on the computer “real-time,” but it’s the same update rate that you have on your system — 2.5, 5, 10, 30, or 120 seconds between updates.
