It's interesting how you went from not familiar with the Segway leveler to the Reticle-Tru being much better in the space of a couple of posts.
This is not a comment on Jerry's product since I haven't tried it. It may well be the greatest ever.
You're quick on the uptake, mathman...
I was familiar with the Segway Leveler and had handled one before. I just didn't remember the name, as I don't own one. When I saw it on Ebay, I reestablished the association.
If you ever try a Reticle-Tru, you'll like it. It's a lot more robust than the Segway Leveler, nothing to break.
