Many will say that the Alpha is not a particularly good training collar because changing the intensity of stim requires more time and attention than a dedicated training collar. I run an alpha 100 and it is true that changing intensity level or switching between tone and vibrate takes multiple screen touches. However, it is a simple matter to program each training button with a different intensity level for a specific collar, which will give you three choices right at your fingertips. That helps. I suppose where it would really fall short is for a pro trainer working multiple dogs in a day, each with possibly a different tolerance for stim. Or needing multiple stim levels for multiple dogs on the ground at once.
I run two dogs. I set up my alpha with one button for tone on the older dog, one button for tone on the younger dog, and one button for appropriate stim on the younger dog, all on the same compass screen. In addition, each dog has it's own compass screen set up with all three buttons programmed with tone or varying stim levels for that dog.
In many years of using an Alpha 100, I've only used the map page a few times. Once was to retrieve a dropped bird (dropped by a person, not a dog). And maybe a couple times for boundaries or geographical "context" as someone else described. The compass screen is it for me. Without my Alpha I'm not sure I would run two dogs at once and I would definitely spend a lot more mental energy and attention tracking my dog(s).
