I find that geared heads lead the way for precise positional adjustments of my camera when using a tripod. Especially for the likes of landscape and architectural shooting, I can make the finest adjustments to keep my horizon level and ensure that uprights are unerringly upright. The range of adjustment is often far greater than I need for these sorts of scenarios, as well as for shooting extreme close-ups.
The Novoflex Qube Goniometer system aims to take accuracy to the next level but with a more limited overall range. Derived from two Greek words, Wikipedia states that "a goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position". Enough said.
