Here is the special informastion about PICUS. In Japan it is not popular but all over the world about more than 70 have sold. However, there are difference between Japan and foreign market and types of trees so in the world they usually measure bigger trees. Moreover, this will be the reference for the user who want to measure as professional or user of other sound wave equipment.
