All these things do is move a dish and save the positions. I tell mine where to go, and it goes-every time, hitting all the birds out there in the arc that I can see, without requiring a dish mover that's "more accurate". How much more accurate does a mover really need to be?
That is true! What unit do you have???
There have been issues brought up not too long ago about different positioners.
A couple of things mentioned were motor load handling, number of positions
and just the overall quality of the units.
If there is no difference then why do newer models come out and replace
the previous one so quickly???
Another thing is why do they make these units so ugly???!!!...
