RX1000 vs CRF 1200 for long distance

The more powerful the maximum range of a rangefinder, the further it will range smaller objects. The [link=http://www.opticsplanet.com/leica-brand.html]Leica[/link] is my favorite overall [link=http://www.opticsplanet.com/rangefinders1.html]rangefinder[/link] because of its superb optical quality and simplicity. For maximum range in a unit I would look at the [url=http://www.opticsplanet.com/bushnell-pinseeker-1500-slope-laser-rangefinder.html]Bushnell Pinseeker 1500 with slope[/url]. This is in lieu of the Elite 1500 that was discontinued last year. Great unit, although it is set in a first priority mode. You can use the scan feature if you need it. This is a larger unit compared to others, but the optical quality is great, and it is very powerful.

I tried the [link=http://www.opticsplanet.com/leupold-brand.html]Leupold[/link] RX1000 and it is a very nice unit that will range large trees, large boulders and other large structure out to around 750 yards in the early morning or evening, but on a bright day only to about 550 yards, sometimes less. How does the [link=http://www.opticsplanet.com/leica-brand.html]Leica[/link] CRF 1200 compare with this? I'm looking for the best distance ranging for hunting antelope and western deer and Elk at long ranges. I know that I can't range the animals themselves at these long distances but I would range trees, hills etc that were at the same distance.
Thanks for your help,
