loud battery powered horn wanted

Why not use your voice? You can take it anywhere with you, perfect volume control, no extra weight, can be tuned to say either "Coming through!" or (my preference) "Excuse me, please?".

AirZound etc is for spineless bullies when used against pedestrians.

I use an electric muddy horn(the one with separate button) it`s loud and I`ve never had any problems getting anyones attention with it. Can get them for £11 if you shop.
