I shoot a 5 pin sight & a slider sight.
My 5 pin first pin (top) is 20yds, 2nd is 30, 3rd is 40, 4th is 50, and 5th is 60. I shoot 3D with it so I use all the pins. Now in a hunting situation I rarely shoot over 25yds, maybe my longest kill is 30yds. Majority is under 12yds for me.
Now my single pin when I hunt, I run 2 ways. If I want it fixed and never move it, I have it set at 27yds. So I know I am so many inches high under 27yds to 0 and at 40 yds I know how low I am holding dead on that I have 3 inch drop so within the kill zone. Now if I want to make my slider sight mobile, then I use the tapes and slide the sight accordingly to the animal I range him at.
As far as go to places, that is tough. I won't shop at a Cabela's ever. I have a few within 90 minutes to 2 hours from me. I have a Field & Stream and Gander Mountain minutes from my home. Majority of what I buy if from my local archery shop & support him. Service is better than a box store plus so much turnover at the box stores. You will have a guy here and there know what he's doing but rare and if so it's only 1. But then most the time he is working the day shift and gone when everyone comes in after work and you have the younger people working who are there to make some money & get a store discount.
You have to google looking for the best price, nobody has everything at the best price, some do some don't. I will tell you if you buy something off the internet and then take the item someplace to be installed, that is like a slap in the dealers face and you'll be charged accordingly for the work and in the end it would been probably cheaper to have bought the item from the archery or gun shop cause they then wouldn't charge for installing, most do not.
