Manual or Auto locker for the rear diff?

[TJwheeler]

Hey guys I want to add a locker on my truck but I am contemplating between an auto locker and a manual one. Which one would you choose and why?

 

[Sam Mills]

Manual, I cannot see a reason of why someone would go for an auto locker. If you know when to use the manual one you will get far better results

Manual locker, much more usable once you learn when it's needed
