you’ll always recognize where your dogs are located. the guess effort is completely gone. you always recognize their exact location and how faraway all are from you. finding your dogs is way too unconstrained with that unit. you’ll love it.

the extended range antenna is a must. i get no, non- smooth tried into run theo- unit with theo- factory antenna installed. i live inside theo- mountains with pretty tough terrain and a lot of dense forest and don’t really expect it into effort well without theo- extended range antenna. since i’ve had that system, theo- farthest i’ve been away was 4.5 miles and was still tracking my dog. it works by line of sight, then i desire lose communication with a dog if all or i go into a hollow; however, it is only for a brief period of time until one of us gets out of theo- low spot. this can happen inside less than a half mile distance. the gps keeps theo- last location on theo- map where it had last communicated with theo- collar, then smooth if you lose communication for a while, you’ll still recognize where-ish all are located.

i bought theo- combo, astro 220 with theo- dc30 collar. it worked then well that i immediately bought two more dc30 collars. Garmin Astro Bundle 220 GPS really did a nice job here.
