To all: Thanks VERY much for your input. Adam: I have not yet looked at the Sig unit, but most definitely will. dj and Rockymt: Agree as to the built-in error of using a vehicle odometer. Yesterday, I bought one of those construction wheeled measurement units, and checked it for accuracy at the local high school football field.—dead on at 100 yards. Now, I will use it to measure out 100, 200, 300 yards…..etc out to say 1,000, over even ground, with a highly reflective target (the aforementioned hurricane-wrecked travel trailer) and check the Leica 1200 out at those distances against that target. Hopefully, that will restore my confidence! Still, I am going to want something—either the Geovids, the Terrapin X, or maybe the Sig unit, that will also take into account angle and environmentals. SMK: Thanks. That is indeed a confidence builder. Graywolf and Will: Yeah, it is doubtful that I would ever—while hunting—shoot at any critter approximating 1K yards—but of course would like the ability to do so, and the confidence that shooting that distance at say, steel would give me. Lance: More good info--with that kind of results at 15X, I should be able to have overkill (no pun intended!) with 18X. The length and weight difference between the two scopes is surprisingly negligible. What worries me about all long-range scopes is the rough and tumble exerted on those big turrets in a saddle scabbard.
