I have one with an angled eye piece that i use at the range and it is okay as I can sit it on the table and look through it standing,but the one issue I have is that I think it is harder to line it up where I want it.
Not sure, but think a straight one would be easier to line up wiht the target.
Why do prone shooters use them? I would think if you're in a prone position a straight one would be easier to use?
I have both, I spend alot of time scouting and range work and have taken to perfering the angled peice when scouting(sitting glassing across a Mountain) and the straight one for at the bench but the angled peice works fine there to.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
