These are some of the features of the TT15 and TT15 Mini. For a full breakdown of the similarities and differences between the TT15 and the TT15 Mini, see the buyer’s guide below this review.


  • The Garmin TT15 is a collar receiver device and collar strap that attaches around your dog’s neck, and connects remotely to some of the Garmin handheld models which control the function of the collar device or provide tracking for it 
  • The TT15 is a 2 in 1 tracking and training collar (compared to the T5 for example which is a tracking only collar)
  • It has a top-mounted, high-sensitivity GPS/GLONASS receiver
  • It is compatible with the Alpha 100, Astro 320 and Astro 430 handheld models
  • It uses 18 different levels of static stimulation
  • There is the option for either continuous or momentary (nick) stimulation
  • The TT15 collar receiver allows you to make quick changes (low, medium or high) within a predetermined stimulation level (1-6), whereas linear stimulation allows progressively more stimulation from levels 1 to 18. 
  • Because you have low through to high power output options, it’s suitable for soft through to harder temperament dogs
  • With the Alpha 100, there are also audible tone and vibration training options
  • The Astro 320 and 430 models allow tracking ONLY (and not the above training options)
  • The TT15 is water resistant to 10 meters
  • There’s the ability to remotely operate the LED beacon lights, built in to the dog device, to help locate your dog in low-light conditions.


  • The major drawback for some people will be the cost. But, apart from that, it really is a high functioning and high performing collar

What Might Be The Best Way To Use An E Collar On A Dog?

For professional advice on using a shock or e collar, see a vet or a professional dog trainer, or animals expert.

But, in general, good e collars come with instruction manuals and guides that tell you how to safely and effectively use their product.

Look to buy from a reputable company that cares about the safety and well being of the dogs.

The best way to use an e collar might be as a temporary device for associating negative or undesirable behavior with a cue (such as a vibration or noise), or a stimulus (such as a nick/static stimulus).

They can be used to teach or retrain a certain behavior, and then put away. They may only be brought out again if your dog/s forget that behavior, or need retraining.

So, really, they could be used ideally as a temporary training and teaching tool (not permanent) for happy and healthy dogs. 

If you notice any negative side effects to your dog’s physical or mental health from using an e collar, discontinue use immediately.

The benefits of an e collar might be:

  • You don’t have to set the collar to shock if it has alternative options like tone or vibration
  • The lowest shock settings on good e collars will provide a small amount of discomfort, not pain
  • The feedback to your dog is instantaneous and not delayed
  • It works at range
  • It saves you shouting and getting frustrated
  • + many other benefits
