The work is devoted to the investigation of the accuracy characteristics of reflectorless laser rangefinders. The method of evaluation of accuracy of measured distances for different reflecting surfaces, based on the analysis of differences of measured distances at two reflector positions, fixed independently with increased accuracy, is presented. The measurement technique involved the use of reflective surfaces of two colors set at different angles to the laser beam. The proposed approach was applied to the laser tape measure "DISTO Pro" model of the Swiss company "Leica". For the conditions of real measurements simulated in the experiments, the numerical values of the errors of the examined tape measure were obtained. Based on the results of processing the data obtained, conclusions were made about the possibility of improving the accuracy of such linear measurements.
