Have to add a P.S. here about a few principles that apply to all optical aids. In a good shakedown at a state park and a sporting clays range,
the Bushnell Yardage Pro 450 reminded me once again of the following:
1. Use the smallest telephoto length you need to avoid excess weight and view shake. The Leupold laser rangefinder had a 6x view. Hard to hold it steady enough for a vibrationless view. The Bushnell has a 4x view. Quick and easy to find the target and comparatively little view shake.
2. Start with the most simple setup you might need instead of buying a bunch of bells and whistles you might never use. The Leupold menu was aggravating enough to take hours to set up. It had more options than many users would ever need after satisfying their curiosity, e.g., measuring angles with an inclinometer. Needed to set it differently for views <150 yards and >150 yards. The Bushnell has ONE button. It provides a 4x and measurement view a long way, e.g., at the range the other day it easily went 287 yards, which is farther than anything I have in mind, including a golf drive.
3. Smallest size is not necessarily the most ergonomically comfortable. The Bushnell is small enough and light enough to carry and use as needed without worry about setup and reliability.
4. Cheapest price does not mean something might not be more useful for particular needs than items costing twice as much, e.g., this particular Bushnell model is 60% of the cost of the Leupold RX-II.
The Bushnell Yardage Pro 450 has now joined my kit for all shooting and golfing excursions. For example, it allowed me to precisely determine various launch machine ranges in sporting clays. As I suspected, many were farther than many shooters think they are.
A particularly difficult rising teal is launched from 55 yards away! Many shooters flail away with Improved Cylinder chokes ineffective at that distance.
The Bushnell showed that most sporting clays at this particular range are shot between 25 and 40 yards, but a good number are shot 45 to 55 yards and sometimes ever farther, which is getting extreme for reliable shotgun work.
Convinced me to change my basic choke from IC to Modified, a fundamental improvement. Just one example of the value of laser rangefinders in many activities.
