The LVE is the top-of-the-range Luo Pan. Supplied with an optical device for surveying the site, it is the world's first "see through the lens" Luo Pan, and the most accurate Luo Pan for positioning water courses, entrances, and all other cures and enhancements. Comparing the LVE with other positioning systems such as GPS, publicly available GPS is accurate only to within 2 meters (the military version can pinpoint a position to within 1m). However, the LVE is accurate to within 15cm and is an essential tool in professional Feng Shui practice.
