Well, one of the chief benefits of a baseplate compass is that it eliminates the need to tote a separate protractor. But that function (essentially) requires a clear capsule with meridian lines to align with the map's north lines (of whichever flavor you prefer). So I just don't see the point of this new Cammenga unit.

Here's something else I noticed on the Cammenga site. If you look at the ordering options for the USGI lensatic compass, you have to select Northern or Southern hemisphere. I thought the USGI compass was specifically designed to be usable globally without concern with local magnetic inclination.
