My propointer dosen't sound to good any more cause the two tiny holes keep getting filled with mud and dirt. Iclean it out with a small stick pin all the time but its not as good as new.My question is can you somehow take it apart to clean it ? Has anybody else had problems and how do you clean yours.I want to rinse it with water but don't want to wreck it.Whats the best way to clean it out. The beeping noise is hard to hear.
