FIELD: weaponry.

SUBSTANCE: device for synchronizing the unwinding of blocks of tension cables of elastic elements of a compound bow (DSU BTC EE CB) during firing contains two synchronizing rollers cross-connected with each other by a synchronization cable. One of the rollers is rigidly fixed on the rotation shaft of the cable tension unit (CTU) of the upper elastic element (EE), and the other is fixed on the rotation shaft of the CTU of the lower EE. The rotation shafts of the corresponding CTU are installed in the bearings of the upper and lower supports. The supports are fixed on the corresponding upper and lower ends of the rigid body of the bow from its rear side. The free ends of the tension cables of the upper and lower CTU are equipped with hooks for connecting these cables with the elastic ends of the lower and upper EE, respectively, and with the possibility of tensioning the latter from the front side of the bow.
