Cool. Thanks for bringing that to my attention. Personally I would prefer an actual bubble level since it would work with no batteries and would likely not add as much to the cost of the scope. An electronic version is a great solution and would probably be easier to use than having to look down at a bubble inside the field of view, allowing you to keep your eye on the target.

I never noticed that option in the Sig scopes before since I haven't looked at any Sig optics other than their Romeo 1 MRDS which I own and I like quite a bit. They are offering some cutting edge stuff for sure. I wish more scope makers would offer an internal level either electronic or bubble style. My number one want would be to have an actual bubble level in the Sightron S3 scopes. My guess is the bubble level would cost less than an electronic system.
