They say great things come in small packages — a lot of the time, that’s true. This is definitely one of those times. The Northwest Instrument Mini Prism Package with Plastic Yoke makes it easy to assemble a mini prism for various surveying tasks.
This package comes with five different items: a plastic yoke, a prism mount, a plumb bob point, a prism with target, and a soft pack bag that keeps all these parts together and makes them easy to safely transport.
Mini prisms have a particular place in surveying. They’re smaller in size than other prisms, hence the name. This smaller size means that mini prisms have better positional accuracy. Because of this, there’s less room for error. Mini prisms like this one are therefore preferable for certain kinds of surveying jobs that require a higher level of accuracy, or jobs that require measurements down to the millimeter. Additionally, a mini prism can also be easier to position because of its size.
