I was going to get the 320 &dc50 collars but due to the collars back ordering when they first released got an Alpha instead. By far the best money I have ever spent! Every time I go hunting I like it a little more- I have little kids & they go with me a lot. Whenever the hunts over they are ready to catch up & find a McDonalds and some toys. They used to get pretty irritable before I had an alpha when we spent hours beeping, looking for & catching stubborn dogs! I just need to hit the lottery & get a few more collars- really hoping Garmin releases a track only collar for the Alpha! Just my thoughts!
