I am going to install either a cosine or angle degree indicator from Sniper Tools on my long range setup having never used either before. My question - is there any advantage to installing one versus the other (i.e., angle degree indicator vs cosine indicator)? I understand the cosine math, but I have no idea if one is more accurate than the other. I use a ballistics program that allows me to input one or the other so I'm not worried about that per se. Also, are there any other considerations I should take into account before making this decision? Thanks for the help!

They do the same thing, and same construction. The cosine scale, the numbers are 5 degrees apart, you put that in your memory. Use what you prefer in calc.
