The article is devoted to the theory and practice of market research of the B2C high-tech products. The authors carried out analytical internal research on the Russian market of household laser rangefinders using alternative aggregated economic and mathematical methods. The rangefinders can be used in many areas including machine-building and construction fields. The article confirms the hypothesis that the number of queries on the Internet about laser rangefinders of firms is proportional to their market share, based on which, according to Yandex statistics, a map of competitors was built. Both a separate analysis of the leading products of the companies and a joint analysis were performed. © Published under licence by IOP Publishing Ltd.
