Due to the high kinetic energy of the 90 lbs PRO crossbow, it is recommended that it not be used for everyday training, but rather for specific applications such as hunting or self-defense. Only suitable, heavy arrows (at least 155 grains) such as hunting or bodkin arrows should be used to avoid damage and safety hazards. Regular maintenance of the string and butt caps is also necessary, as these are subject to increased wear at this strength. A suitable target for high-powered crossbows is also required.
