The article characterizes modern information-analytical systems (using Scatt, Noptel, «Mantis X8» as examples) in the training system of athletes. Emphasis is placed on a detailed description and the features of using the shooting analytical system «Mantis X8», which provides feedback on the quality of the shot execution. The purpose of the study was to examine and scientifically describe the mechanism of operation and application of the shooting analytical system "«Mantis X8»" in the training system of athletes. To achieve this purpose, the following research methods were used: theoretical analysis and generalization, analysis of documentary materials; comparison. Results and Conclusions. Based on the analysis of documentary materials and generalization, we considered the existing characteristics and application of optoelectronic devices (such as Scatt or Noptel) in shooting sports. The advantages and disadvantages of using these devices were highlighted. Given the existing research, it was important to update the information about modern information-analytical systems (using «Mantis X8» as an example) in the training system of athletes. «Mantis X8» is a high-tech device for analyzing archery shooting that provides archers with important information about each shot or series of shots. This device attaches directly to the bow and connects to a mobile application via Bluetooth. When the archer releases the string, the sensor collects data about the movements of the bow and transmits them for processing to specialized software, allowing archers to receive objective feedback on their shooting technique. Thus, we have described the principle of operation and application of the device, from which it can be concluded that there is a need to improve the technical preparedness of archers to objectify the control of shot characteristics using the shooting analytical system "Mantis X8" in technical training.
