The Tembo Tusk LoadSpotter is one very unique piece of equipment. A true feat of engineering genius. It uses the concepts of a fulcrum based, strut assisted, expanding and contracting parallelograms to elegantly manage a very heavy object in a three dimensional space. That is a mouthful. And it is so well made that you don't realize the complexity or the robustness of its construction. All you know is that it does its job very, very well.
