Alpha vs Astro 320

Alpha hands down... I've had mine over two years now and love it. I've had the 220 and 320 also... they don't hold a candle to the Alpha. Range, battery life, built in Tri-Tronics, ability to track your buddy's hand held are just a few things I can think of. I usually get three good hunts before charging the collars. The hand held is chargeable also... no more batteries! With factory antennas 1 to 2 miles is no problem... I get 2 to 3 in a lot of places. Like Oconee said... do the updates. Even when you get it in brand new... hook it up to the computer and update everything.
