This is an awesome product. When the dog is wearing the gps collar, I will know where it is and what it is doing all the time. I don't have to worry about losing a dog or it running too long and getting over heated.

My son really loves this unit and was surprised that he could operate it so easily. We need some chip to put in it? Some kind of map...Please let us know what we need...Thanks

I really like my Garmin Astro 320, and it goes great with the T5 collar and helps me find my dog better.

This is an excellent system. I highly recommend.

Used for Mountain Lion hunting, and they been working great!

Great customer service. Best price for a multi dog set. Very pleased with the product and support.

Even better than we thought and better than all my friends' gps!

Works great and easy to use.

The T-5 COLLAR is same as DC- 50. No improved performance or range

Best product on the market!

I use the T5 collar and Astro 320 handset combo just to keep track of my very active dog, so that I can let her run free in remote areas and be able to find her when I need to. The system works great, even in deep woods, and is built very solidly. The lights on the collar are extremely effective for visually tracking the dog in the dark.

Much better performance than my 220 system.

I bought this for my boyfriend for Christmas. It works great, and he loves it! Definitely worth it.

Great product.
