does anyone have a similar problem? When I dive with my instructor's friends, who are all either instructors, or AI.. almost everyone's got a quacker.. problem? Everyone sounds just about the same! So, is there a quacker that has an adjustable pitch? So I can tell who's quacking by pitch?
Maracas don't work either because they all sound alike too.. Or better yet.. how about an electronic beeping device that does combinations of pitches. Kinda like a personal ringtone.
