Note: if the tuning fork does not initiate vibrating immediately upon switch on, a small' pinch/pluck' of one of the tuning fork ends triggers the continuous oscillations heard within a radius of 10-20 feet. This should remind the old timers the days of cranking to start their automobiles! A range of 4 to 8 V DC is safe. Print out of documentation from the web is included for technical details. But be aware that someone else might grab it in the meantime and you are left with procrastinator's remorse!
Approximate Dimensions: 5 x 6 1/2 x 5 inches or 8.5 x 12.5 x 8.5 cm. Weight 5 lbs (2.25 Kg).
