I sure like the "SCRUNCH-SCRUNCH"sound that thing makes when it moves a LOT more than the infernal "BEEPING" that pretty much all heavy equipment makes here in the USA. Makes MUCH more sense to have a sound that can pretty much only be heard as far as the machine could possibly move ins say, 3 minutes, rather than that danged BEEPING that can be heard for miles farther than the machine could possibly move in 10 or 15 minutes and drives everyone crazy. Not to mention that the workers right there at the work site get very quickly immune to the racket and don't even hear the very sound that is MANDATED and is SUPPOSED TO keep them safe!!!
