tape will also quiet it down for those public areas(i did the same with my garrett propointer plus it keep dirt and grime out) on the centec i don't use the speaker so i just cut the wires so mine only vibrates. for a 16 dollar pinpointer and less than 10 bucks in mods. ya really can't beat these.....plus it was something to tinker with since i can't seem to leave anything alone
