Garmin introduces the Garmin Astro 320 with T5 Tracking Collar, the latest in dog tracking technology. It was created with the serious hunter in mind and is equipped with numerous advancements over previous GPS dog collars. You can now have more accurate and constant tracking than ever before.

Key Features of the Astro 320/T5 Tracking & Training Combo

Improved Tracking

It is now less likely for your GPS dog 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 technology your tracking and training collar can receive signals from a total of 49 earth orbiting satellites. That’s 21 more satellites than the TT10.

Rescue Mode

This feature, if enabled by your Astro 320, 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 GPS dog collar detects its battery has decreased to 25% of its full charge, it automatically begins to conserve its battery 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.

Upgraded 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 320 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 separate ways to charge the training 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 your T5 tracking collar needs a software update. All that’s required for an update is to attach the charging clip, plug the T5 Garmin tracking collar into a computer and run Garmin Web Updater.

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 dog tracker 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 successful completed the task.

Private PIN Lock

While linked to an Astro 320 dog tracker, users can choose a 4-digit code for each T5 tracking collar. This code must be entered before someone else can track that T5 collar. It may not seem crucial during a normal day to day hunt but could prove priceless while competition hunting, or in large hunting groups.

Adjustable Dog Tracker Status

Using the updated Astro 320, you can change the status for each of your dog’s 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.

Smarter Power Button Placement

The location of the power button is very important; we often see both the DC30 and DC40 with wear on the rubber cover that seals the power button. This makes it very easy for moisture to cause corrosion in the track and train collar, eventually causing damage that sometimes cannot be repaired.

The power button on the T5 Garmin Tracking collar is located on the bottom of the collar box which protects from this every day wear and tear. This also prevents the collar from being accidentally turned off when struck by something on a hunt.

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.

Track 10 Dogs

The Astro 320 allows you to track a total of 10 dog collars simultaneously.

Wireless Collar Updates

The Astro 320 makes it easy to update collar software on the go. This enables you to execute some trouble shooting even when you are in the field.


The Garmin Astro’s USB port makes it easy to plug 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.

Covey Counter

Record the specific location of coveys, the birds in a covey, and the number of birds taken from the covey using waypoints.

Product Review Summary:

Astro 320 with T5 Combo Click Here for our Pro Staff Review Article for Garmin T5 and TT15 Collars.

Garmin has recently released the Garmin T5 and TT15 collar, the most notable difference and improvement for the T5 is the ability for it to be tracked as a “track only” collar for the Alpha 100. It also should be noted that the features and configuration for the T5 Tracking collar were selected for the competition hunter in mind. You will notice that some of the features for example Bark Detection were eliminated on the T5 to comply with competition rules.


· During our time in the field this collar proved to be dependable and reliable.

· Peace of mind knowing the T5 collar is tracking with GLONASS.

· Having a collar that can be tracked on my Alpha 100 without stimulation prongs that can, and have, created irritation to at least one of our smaller sized dog’s neck while hunting in heavy brush.

· Rescue battery life with rescue mode allows me to focus on what matters, my dog not how much battery life I have left on my collar.


· At $249.99 The T5 collar price is higher than its predecessor.

· The T5 was designed for Competition Hunters needs in mind, which means there are some features that are disabled that a Pleasure Hunter would appreciate. For example, the T5 does not have Bark detection.

· The battery life on the T5 is slightly lower than the DC50.

Garmin T5 vs. Garmin DC40

There are a couple major reasons why you would want to upgrade to the Garmin T5. First is the greatly improved satellite reception you’ll enjoy: one of the most significant improvements in the T5 is its top-mounted GPS receiver and antenna, which assures quicker satellite acquisition and more consistent satellite connections when your dogs are in heavy cover out in the field. In addition, Garmin has enabled the GLONASS system of satellites for your T5 and updated Astro 320. This enables you to receive signals from 21 more satellites helping to pinpoint your dog’s location.

Thanks to Rescue Mode, a great new feature with the T5, you’ll also enjoy the “peace of mind” knowing you have longer battery life than with the DC30 or DC40 dog tracking collars. Rescue Mode was first introduced in 2012 on Garmin’s top-line Alpha TT10 collars. Basically, it slows the collar update rate from once every 5, 10, or 30 seconds to once every 2 minutes to conserve battery life after your T5 battery has diminished to 25% of its full capacity. Having extra time could be critical when attempting to recover a wayward hound.

Another critical improvement in the T5 dog tracking collar over the DC40 is the longer braided steel antenna. The design and construction of this VHF long-range antenna provides up to 30% more tracking range than you get with the DC40. The T5 antenna is also much more durable and less prone to damage than the copper-wound stubby antennas on the DC40 and DC30 GPS tracking collars.

Lastly, some of the finer performance details that separate the T5 from its predecessors include its versatile, user-friendly charging system and beep-tones that confirm when you add collars or change settings on the T5 dog tracking collar.

Battery Life

Garmin Astro 320 GPS Handheld: Using two AA batteries (not included), the battery life of the Astro 320 can last up to 20 hours. This can be prolonged by using the vehicle charge port so that your handheld will rely on your car’s battery instead. In any case we recommend using rechargeable AA batteries for the Astro.

Garmin T5 GPS Tracking Collar: With rescue mode on, the T5 has around a 30-hour battery life. Here’s how: 5 second update rate means around 13 hours (before battery reaches 25%). When battery reaches 25%, rescue mode changes the update rate to 2 minutes. A 2-minute update rate means about 16 additional hours, totaling out to approximately 30 hours.

Update Rates/PIN Lock

This combo allows you to control your battery life with features that change the update rate. With the Astro 320/T5 combo, you can choose whether the collar is updated every 5, 10, 30, or 120 seconds.

For the times you might not want other people in the field to track your dogs, PIN Lock is very helpful. With it, you keep others from seeing your dog on their handheld. How it works is you assign a 4-digit code to each dog’s collar and then for anyone to view your dog, they must first enter that dog’s code. If your hunting partner wants to track one of your dogs, you can simply give them the code. This function is not required and can be turned off at any time you feel it is unnecessary.

The Astro 320 is not only proficient for tracking and managing dogs, but also is an exceptional tool in other recreational activities. The Astro can function like any other Garmin GPS when it is not being used to track dogs. It can also be convenient for hiking, camping, geocaching, and deer or elk hunting. Simply take off the VHF antenna and cap the SMA connector to create a portable and fully operative GPS complete with many of the high-end functions of other Outdoor GPS devices.
