A used Leica 1200 or Bushnell 1500 . My Leica 1200 Scan was good to about 900 yards , but I have seen Reports from others that worked a bit further . Some Bushnell 1500s will top that Range . I have found a LOT of variability within the same Model and Brand of LRFs , and some duds too ! Try to Test one out before you buy ....if possible .
