Its bombs were reported to be extremely loud, but very inaccurate and otherwise of little value beyond terrifying opponents; they proved particularly useful in scaring away both Arab soldiers and civilians.
This contributed to the weapon's notorious inaccuracy, as the shell lacked adequate guidance during the launch phase to acquire aerodynamic stability in the intended direction.
Small pieces of metal and tubes were welded onto the outside of the casing, reducing the weapon's accuracy even further than its already non-aerodynamic design, but contributing greatly to the whistles and shrieks which it made when in flight.
The noise was its most important effect, so that anyone attacked by a Davidka mortar would hear the shell seeming to fall very near to them before bursting very loudly, increasing the fear factor.
According to Palestinian historian Walid Khalidi, the Davidka carried a bomb that weighed 60 lb (27 kg) and caused fear and panic when used in built-up areas.
