I'll start off by saying this comparison is not apples to apples. The Leica CRF 1200 is discontinued and the Leupold RX-1000i is a brand-spanking-new product (at time of writing). This means that technology has changed, and probably gotten cheaper to produce between the product lifetime of the Leica and the introduction of the Leupold. That being said, the reason I am comparing these two is because the Leica is available used for around the same price point as the Leupold is new. What this means is folks looking to spend about $400-$500 on a rangefinder (as I was) may consider these two options.
For those individuals, I offer the following comparison of ranging capabilities from both models so that an informed purchase can be made.
Rangefinders:
Leupold RX-1000i
Product information
Leica CRF 1200 (discontinued)
Product information
Location:
37.775765° N 122.435249° W
Weather:
Temperature: 61°F
Pressure: 29.88 in
Visibility: 6.0 mi
Humidity: 67%
Wind: From W at 20mph
Targets:
Alpha: (Bus stop)
Bravo: (Yellow building)
Charlie: (Restaurant at intersection)
Delta: (AC unit on retirement center)
Echo: (Parked car)
Notes:
Every reading taken 2-3 times to verify.
Readings taken while seated, using arms/legs for support. No tripod or solid rest.
Settings:
Leupold: TBR (true ballistic range) , BAS/AC (Ballistic setting for .308win and similar), Output in meters.
Leica: N/A
Results:
Leupold RX-1000i:
A: 138m
B: 371m
C: 431m
D: 596m
E: 907m
Leica CRF 1200:
A: 154m
B: 407m
C: 475m
D: 652m
E: 991m
Additional feedback:
The Leica screen is not as bright as Leupold, making it difficult to read results in bright daylight.
The Leupold is much more intuitive than the Leica when it comes to changing the settings, but it has the advantage of having an additional button. Still, it doesn't make me read and remember the number of times the screen blinks (even harder when you consider the previous point). To make it even easier, the Leupold comes with a handy little plastic instruction card that fits into a tiny back pocket of the carry case.
Both rangefinders were able to range targets with an equal level of difficulty/ease, depending on the distance. That is to say, one did not range targets easier than the other. As noted earlier, I believe I would have improved my ability to range targets with the use of a tripod or rest.
I sincerely hope this report helps some folks make an informed decision with their purchase. Thanks for reading!
