I use the Bushnell Fusion 1600 10X binoculars. In fact Because they cost $800.00ish, I have two pairs.
Friends I hunt and shoot long range with have Ziess, Swaro and Leupold.
I have great things to say about all of them except the Leupolds. He leaves them at home now because he went out and got a set of the Fusions.
The Bushnells range very, very well, are very clear to look through and have some very nice options.
One I find that sets them apart from the Swarovski 8X30 and the Ziess binos is that those guys have to let go of the button to get the reading, with the Fusions you keep it held and steady and the numbers come up automatically.
The Bushnells have a focus adjustment for each eye and have Elite optics, so I have glassed along side the Ziesses and others for long periods of time without getting tired eyes.
The Bow drop calculator is very good. The rifle balistic program is a good general guide line that will get you close to what you need for the kill zone of a large animal, which is all it is meant to do.
Get your ballistics, hand held weather station, shoot to prove your load at 50 yard ranges out to the max of your capabilities and range your target with a good rangefinder and the rest is up to you.
But If you get a chance to try these Bushnell Fusions you can decide if they work for you or not.
All of my pals who have more and less costly models very much like them and have borrowed my scond set from time to time with confidence.
Good luck, have fun and be safe.
