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 Garmin T5 Dog collar is the top-mounted GPS receiver and antenna, which assure quicker satellite acquisition and more consistent satellite connections when your dogs are in heavy cover or deep canyons. In addition, Garmin has enabled the GLONASS system of satellites for your new GPS tracking collar. With an updated Astro 320 you’ll have 21 more satellites available to help pinpoint your location as well as your dogs.

This is one of the most user friendly dog tracking collars on the market.

The receiver I obtained is the 16 channel module that is used to track Alzheimer patients and is comparable in price to the ten channel model. The collar is very lightweight and even my smallest dog, Casey, who weighs 18.5 lbs., has no trouble handling the weight. The range of the 3850 is claimed to be three miles.

Tracking collars give very limited information on distance. With a tracking collar it's more about direction than distance. You can estimate the distance based on the amount of gain (signal strength) that is required to get the signal from the tracking collar, but this can change based on the terrain that is between you and the dog.
