Free: Contests & Raffles.
My Zeiss RF will do it every time and quickly. My Swarovski would definitely do it, but has to "think". My Geovid HDs will do it, but not as consistently as the Zeiss or Swarovski. The Zeiss is the most consistent/responsive.
Ordered up a Bushnell Elite 1 Mile ARC. Will have a quickie review in a week or so.
