Sunshade or Off?

Hello everyone!
I just acquired a Burris FFII from a TW member. I got a great deal and the scope came with a sunshade and scope covers. I've never used a sunshade before so I'm not shure what the benefits/disadvantages are so I render you the question,
sunshade on or off?

Additional Details:
-Scope is 4.5-14x42
-Going on my Vanguard 30-06
-It's my "go to" hunting rifle

Thanks for your input

 

The sunshade helps when shooting in bright conditions, or when you're set up in the morning to hunt toward the east, where you might experience glare with the morning sun. It also helps some when you're hunting/shooting in the heat and experience barrel mirage after a few rounds.

You can leave it on the whole time if you want - the only time it might hurt is shooting in last-light, because it will reduce the light coming into the scope some.

And one more thing - if you use the sunshade, it will sort of lock the objective in place if you snug it down all the way, so you might want to set your objective then snug up the sunshade. Enjoy the scope!

 

Thanks for the info bro.
