Trailer...have you not used it past 100 yds. because you haven't tried yet or you feel it wouldn't do you any good? My Zeiss Conquest is 3.5-10X and thats easy for me to see my holes at 100, but impossible at 200. thats where I want the spotting scope to come in. I agree with side by side comparison but the problem with looking at them at a store is, nothing is 200 yds away. The clowns in town won't let you take them outside to compare, so I have already reserved that I'll be buying it on line, either e-bay or Cabelas. JDinAB
